# openLA500
## 前言
openLA500是一款实现了龙芯架构32位精简版指令集（loongarch32r）的处理器核。其结构为单发射五级流水，分为取指、译码、执行、访存、写回五个流水级。并且含有两路组相连结构的指令和数据cache；32项tlb；以及简易的分支预测器。此外，处理器核对外为AXI接口，容易集成。
OpenLA500已经过流片验证，.13工艺下频率为100M，dhrystone，coremark分数分别为0.78 DMIPS/MHz(指令数有点高)，2.75 coremark/Mhz。软件方面，uboot、linux 5.14、ucore、rt-thread等常用工具及内核已完成对openLA500的适配。
详细设计报告见doc目录。

# 运行流程
1. 在解码阶段解析 lacc 指令，并将 op 和 imm 发送给执行阶段
2. 在执行阶段`lacc_req_valid`为1，lacc接口将接受 lacc 指令并暂停，直到`lacc_rsp_valid`为高才会将指令发送给下一级
3. 如果需要访存，可以将 `lacc_data_valid` 置高并设置访存地址及大小等信息。当`lacc_data_valid`和`lacc_data_ready`同时为高则当前请求成功发送至dcache。
4. 当指令执行完成之后将`lacc_rsp_valid`置高，指令将从 exe 级继续执行
lacc读请求时序,读取地址为0x1C0FFF38，读取数据为0x00000000
![](./picture/lacc_read.png)
lacc写请求时序，写入地址为0x1C0FFEE8,写入数据为0x70A3A52B
![](./picture/lacc_write.png)
# 自定义指令
添加自定义指令只需两步：
1. 修改`mycpu.h`中的`LACC_OP_SIZE`为自定义指令数量（若`LACC_OP_SIZE`为1需要修改`LACC_OP_WIDTH`为1），并且取消`HAS_LACC`的注释
2. 在`lacc_core.v`中删除示例`lacc_demo`，写入自定指令代码
# demo
demo实现了从两个地址载入向量，点乘之后再存入缓存中的功能，代码位于`lacc_demo.v`中。
## 指令
| 指令 | op | rj | rk | 描述 |
| -------- | ---- | ----- | ----- | ----------------------------------------------- |
| op_cfg | 1 | size | waddr | 设置写回地址及向量长度 |
| op_lmadd | 0 | addr1 | addr2 | 设置需要计算的两个内存地址，对位相加再存入waddr |
## 状态机
| 状态 | 说明 | 转换条件 | 下一状态 |
| --------- | --------------- | ----------------------------------------- | --------- |
| IDLE | | lacc_req_valid & op_lmadd | REQ_ADDR1 |
| REQ_ADDR1 | 访问addr1的数据 | data_hsk(访问addr1数据) | REQ_ADDR2 |
| REQ_ADDR2 | 访问addr2的数据 | data_hsk(访问addr2数据) | FINAL |
| FINAL | 计算结果并写回 | data_hsk & req_size_nz(写入数据且size!=0) | REQ_ADDR1 |
| FINAL | | data_hsk & ~req_size_nz | IDLE |
data_hsk即`lacc_data_valid & lacc_data_ready`，表明当前访存请求发送成功。
**数据控制**
使用buffer_valid信号表示第一个地址的数据是否被接收。wdata_valid表示写回数据准备完成
当`buffer_valid & lacc_drsp_valid`为高时说明第二个地址的数据已经返回，在该周期计算`buffer_data+lacc_drsp_rdata`并写入wdata
# 修改编译器
我们可以使用".word xxxxxxx"的格式在汇编中添加自定义指令。但是这种方式阅读不够友好，并且不利于操作数读写，例如
```c
asm volatile (
"move $r5, %[addr]\n\t"
"move $r6, %[para]\n\t"
".word 0xc00018a0\n\t"
::[addr]"r"(addr),[para]"r"(para)
:"$r5", "$r6"
);
```
**修改编译器**
我们可以修改binutils使得编译器可以识别自定义指令。
- 下载loongarch toolchain: https://gitee.com/loongson-edu/la32r-toolchains/tree/master
- 进入src/la32r_binutils/opcodes,打开loongarch-opc.c,在`loongarch_fix_opcodes`结构体中添加
```c
{0xc0000000, 0xf0000000, "lacc", "u22:6,r0:5,r5:5,r10:5,u15:7", 0, 0, 0, 0}
```
- 根据toolchina的README编译，并将bin目录添加到path中
自定义指令的格式为:
```
lacc command, rd, rj, rk, imm
```
上例可以修改为：
```c
asm volatile (
"lacc 0x0, $r0, %[addr], %[para], 0x0\n\t"
::[addr]"r"(addr), [para]"r"(para)
);
```

# 分支预测
分支预测即根据分支历史，提前预测指令跳转方向及跳转目标。分支预测器种类繁多，例如BTB（Branch Target Buffer）、BHT（Branch History Table）、RAS（Return Address Stack）等，但适用于五级流水的其实并不多。如设计概述中所介绍的，五级流水中，pfs级发出取指请求，fs级取回指令，ds级开始译码，并明确跳转指令的所有信息。也就表示分支预测只有一拍的空间可以利用，且无预译码，可依据的信息只有pc，跳转方向及跳转目标都只能靠猜。适用的实际上仅有BTB。不过对于较为特殊的jirl指令，即寄存器跳转，若直接采用BTB的机制，会使得命中率极低。因此，在BTB的基础上进行改造，由CAM表记录jirl指令的pc，并由RAS机制预测其跳转目标。
----
接下来介绍分支预测器的具体实现，分为两点：分支预测器的内部实现；分支预测器同流水线的交互。
## 分支预测器设计
分支预测器的逻辑可以分为两个部分，由PC进行预测跳转目标及跳转方向的预测部分；根据指令译码结果与分支预测器预测结果的比较，对分支预测器历史信息进行修正的修正部分。
### 预测部分
首先来看模块的接口。
- fetch_pc：取指pc
- fetch_en：取指使能
- ret_en：预测结果使能
- ret_pc：预测跳转目标
- taken：预测跳转方向
- ret_index：指示当前预测结果的对应项，用于修正
btb表有32项，包含四个内容：
- btb_pc：30位，用于和取指pc匹配
- btb_target：30位，存放跳转目标
- btb_counter：2位，由最高位指示跳转方向
- btb_valid：1位，当前项是否有效
对于jirl指令的预测逻辑由两部分组成，16项的CAM表以及8项的RAS。
CAM表包含两个内容：
- ras_pc：30位，用于和取指pc匹配
- ras_valid：1位，当前项是否有效
RAS简单来说就是一个栈。存储30位的跳转目标，由ras_ptr指示栈顶。
明确表项内容后，来看预测逻辑。fetch_en以及fetch_pc进入分支预测器时，首先缓存一拍。单看分支预测器，缓存插在什么位置其实都可以，只要有一拍的延迟即可，但考虑到赋值nextpc即fetch_pc的路径非常长，因此将缓存插在靠前的位置。缓存后的信号为fetch_en_r及fetch_pc_r，将其与两个CAM的PC部分，btb_pc和ras_pc进行匹配。该项有效且pc匹配则表示命中。命中项记录在btb_match_rd和ras_match_rd中。
两个表中有一项命中，则置起ret_en。若命中在btb CAM表中，ret_pc取对应项的btb_target即可，若命中在ras CAM表中，则取ras栈顶的跳转目标。理论上btb_match_rd和ras_match_rd为one-hot且只会命中在一个表中，因此不必使用优先级逻辑。ret_index同理，而taken在btb_match时，需要看对应项btb_counter最高位，而ras_match时，直接置为1。预测阶段不会对分支预测器的历史信息进行任何修正。
### 修正部分
在ds译码级，汇总分支预测信息以及译码得到的正确分支跳转信息。
预测信息同上：
- ds_btb_target
- ds_btb_index
- ds_btb_taken
- ds_btb_en
正确的分支跳转信息如下：
- br_to_btb：表示当前指令是否为分支预测器所覆盖的跳转指令，当前结构的分支预测器覆盖所有跳转指令。
- br_taken：跳转方向
- br_target：跳转目标
译码级根据以上信息，稍加分析并传递至分支预测器，传递信息包括：
- operate_en：分支预测器修正操作使能。注意该信号需要在ds_ready_go、es_allowin和ds_valid为1时置起且无例外。只有ds当拍允许流动至下一级时才能发出修正操作。对于ds_ready_go，因为流水线中指令寄存器的依赖有可能导致ds阻塞，阻塞时指令所得到的寄存器值是错误的，即译码得到的分支跳转信息也是错误的。而es_allowin的介入使其操作使能仅维持一拍，避免重复操作。
- operate_pc：修正操作针对的分支指令的pc
- operate_index：修正操作针对的CAM表项
- pop_ras：为jirl指令时置起
- push_ras：为bl指令时置起
- add_entry：当前指令为分支指令但预测器未进行预测时置起。这里与上了一个额外条件br_taken，因为当pc在分支预测器中未命中时，顺序指令，也算是预测为untaken。br_taken不为1时，并不需要在预测器中建项
- delete_entry：当前指令不为分支指令但预测器进行预测时置起。这种情况出现的概率极低，只有在自修改代码中，可以不用考虑
- pre_error：当前指令为分支指令且预测器进行预测，但跳转目标不一致时置起
- pre_right：当前指令为分支指令且预测器进行预测，且跳转目标一致时置起
- target_error：当前指令为分支指令且预测器进行预测，且跳转目标一致，但跳转目标不一致时置起
- right_orien：正确的跳转方向
- right_target：正确的跳转目标
分支预测器会根据以上信息进行修正，首先由pop_ras即是否为jirl指令区分当前操作的是BTB部分还是RAS部分，针对BTB部分，操作类型包括：
- 建项：add_entry置起时。使能指定项，并填入operate_pc和right_target，以及初始化btb_counter为2'b10。对于填入项即index的选择，若BTB CAM表中还留有未使能项，则选择其中一项。若所有项都有效则选择btb_counter为2'b00的一项，即大概率不跳转的预测项，因为未在btb中命中的pc即预测为不跳转，两者效果是相同的，只不过该pc若下一次为跳转，则会重新建项，相当于将其btb_counter由2'b00直接转为2'b10，很有可能导致下一次的预测出错。但是这种情况出现的概率肯定比替换掉其他btb_counter的值导致下一次预测错的概率低。若所有项都有效且btb_counter都不为2'b00，则随机选择一项。
- 修正跳转目标：target_error置起时。重新填入right_target，并初始化btb_counter为2'b10。
- 修正跳转方向：pre_error或者pre_right置起时。根据right_orien调整btb_counter，若正确的分支方向为taken则累加，若为untaken则递减。
针对RAS部分，操作类型包括：
- 建项：add_entry置起时。使能指定项，填入operate_pc即可。相当于预测pc的分支类型。index的选择同BTB部分。
- 进栈：当push_ras置起且当前RAS非满时，存入当前pc的下一条指令，并将指针上移。即当前为bl函数跳转指令，其返回地址为bl的下一条指令。RAS指针指向的是空项。
- 出栈：当pop_ras置起且当前RAS非空时，指针直接下移一项即可。
## 分支预测器与流水线交互逻辑
首先简单介绍取指逻辑，该部分内容会在后续逐步展开。来看几个关键信号，inst_valid指示当前取指pc是否有效，该信号直接送往icache等待接收。inst_valid主要看fs_allowin信号，即pfs指令允许向后流动时，其取指pc即为有效，能够避免相同pc取指请求的重复发出。nextpc即为取指pc，当前仅关注其最为常规的pc来源seq_pc，顺序取指pc。当inst_valid为1时，并不代表取指请求即刻便能发出，还需要等待icache空闲，由inst_addr_ok表示（取指请求的其他去向tlb、btb不需要等待）。当inst_valid && inst_addr_ok为1，取指请求发出，pfs_ready_go置起，pfs向fs流动。
fetch_en和fetch_pc发送至分支预测器后，下一拍得到预测结果（btb_en/btb_ret_pc/btb_taken）。当btb_en && btb_taken为1时，fetch_btb_target置起，分支跳转，将nextpc纠正至btb_ret_pc。这段逻辑中有一点需要注意，分支预测器返回的结果仅维持一拍，但pfs并不一定能够向后流动，因此需要缓存分支预测器的返回结果，避免信息丢失。分支预测器的返回结果缓存在btb_lock_buffer中，由btb_lock_en指示缓存是否有效。缓存条件即为分支返回结果且pfs无法向后流动（btb_en && !pfs_ready_go），缓存释放条件为下一次取指重新发起。而nextpc的维护以及fs向ds传递分支预测结果时都将采用btb_ret_pc_t、btb_ret_pc_t、btb_ret_pc_t、btb_ret_pc_t信号，由分支预测器返回信息和缓存的信息相或得到，两者同一时刻仅有一个有效。
译码级，根据译码和分支预测的结果，能够知道下一条指令取指的方向是否正确。取指级有两个方面的工作需要完成：修正分支预测的历史信息；若预测错误则需纠正取指方向。此处主要讲述第二方面的内容。若译码级检测到分支预测错误，则会置起btb_pre_error_flush信号，由该信号修正取指方向，该工作可继续细分为两个内容
- 取消掉下一条进入译码级的指令，及错误预测导致错误取指的指令
两种情况需要考虑：
- 当该分支指令向后流动的那一拍，即（btb_pre_error_flush && es_allowin）为1时，若下一拍下一条指令紧接着进入译码级，则可直接取消。不过可以用更粗犷的方法，即下一拍的ds_valid直接为0，无需识别是否有指令进入。
- 同样的条件，若下一拍无指令进入，即当拍fs_to_ds_valid为0，则置起branch_slot_cancel触发器。该触发器为1时，会等待下一条指令进入，当检测fs_to_ds_valid为1时，将其取消，并恢复branch_slot_cancel至0。
- 纠正nextpc。当译码级发现分支预测错误，会将正确的跳转目标（btb_pre_error_flush_target）和使能信号（btb_pre_error_flush）通过br_bus传递至取指阶段，修正nextpc。
需要考虑两个问题：
- 当nextpc修正信息向前传递时，pfs并不一定处于能够取指的状态，例如inst_addr_ok不为1。此时若译码级不阻塞，且pfs不将修正信息存入buffer，会导致信息丢失。
- 译码级会记录分支预测错误，并取消掉错误预测的分支指令的下一条指令。若pfs在取完预测错误的分支指令后始终处于阻塞状态，之后直接被修正至正确的跳转方向，则会导致正确的指令被取消掉。
针对上述两个问题，可在pfs中构建一个状态机解决。br_target_inst_req_state表示状态。当发现预测错误后，根据流水线状态，进入不同的状态。
- !fs_valid && !inst_addr_ok：预测错误分支指令取出后未进行任何取指，因为fs级为空，inst_addr_ok从未置起。且当前也不处于可取指的状态。进入br_target_inst_req_wait_slot状态。
- !inst_addr_ok && fs_valid：已有一条错误取指的指令在fs中，但pfs并不处于能够取指的状态。进入br_target_inst_req_wait_br_target状态。
- inst_addr_ok && !fs_valid：预测错误分支指令取出后未进行任何取指，当前处于可取指的状态，但当前的指令会在译码级取消。进入br_target_inst_req_wait_br_target状态。
br_target_inst_req_wait_slot状态会待取指请求发出后切换至br_target_inst_req_wait_br_target状态，该状态便会将nextpc修正至存储btb_pre_error_flush_target的pc buffer（br_target_inst_req_buffer）。当取指请求再次发出后，状态切换至空状态br_target_inst_req_empty。
构建状态机后，还需要注意一个问题。也许pfs处于即刻能够发出取指请求的状态。可粗略的判断fs级是否有指令，便改变next_pc同时置起inst_valid，即使当前无法取指(inst_addr_ok为0)也没有关系。

# 设计概述
![系统框图](./picture/框图.svg)
系统框图展示了OpenLA500处理器核的内部结构。指令的执行始终按照取指、译码、执行、访存、写回的顺序进行。各级流水会存储指令执行的中间状态，在完成当前阶段的操作后，将结果存入下一级流水，进行下一个阶段的操作。
## 执行流程
处理器核内维护`nextpc`信号，表示取指地址。待取指开始时，`fetch_pc`会发往`icache`、`tlb`、`btb`进行不同的工作，以及存入触发器。在下一拍即`fs_stage`取指级,`btb`完成分支预测，将结果直接送往`nextpc`，更改其取指方向。以及由`fetch_pc`以及`tlb`虚实地址翻译的结果，在`icache`指令缓存中得到`inst`指令码，并存入触发器。下一级`ds_stage`译码级在拿到指令码后，便交给`decoder`进行译码。译码后可以得到具体的操作码`op`，以及寄存器号，并可借此在`regfile`寄存器堆或者`csr`控制寄存器中索引到寄存器值`rf_data`。`es_stage`执行级在得到操作码及操作数后，便可送至`alu`运算部件进行简单运算，以及送往`div`除法部件、`mul`乘法部件进行多拍较复杂的运算。此外，由`alu`可以得到访存地址，并发至`tlb`及`dcache`数据缓存完成访存请求的处理，基本同`icache`。在`mem_stage`访存级，可得到访存、乘除法的运算结果，并由`op`选择最终的运算结果`final_res`，并存入触发器。`wb_stage`写回级便会将最终运算结果写回到`regfile`及`csr`。对于`i/dcache`，若取指/访存请求缺失，便会发送请求至`axi_bridge`并通过标准的`AXI3`总线协议与外界通信。
---
流水级的各阶段需要与其他不同的模块进行交互，确认其任务是否完成。以下针对流水级及各模块进行介绍：
## 取指阶段
### `pfs`
该级流水的主要功能是维护`nextpc`，也就是流水线取指的虚地址。其实从更为严谨的角度来看`pfs`并不应该单独称为一级流水，因为`nextpc`为`wire`类型，或者说`pfs`在正常的执行流程中不会缓存信号，当拍便可获得取指方向。实际上`pfs`为各级能够影响取指地址的流水级的衍生。`nextpc`的维护逻辑可以说是五级流水中最为复杂的一部分，因为`icache`并不是时刻处于就绪的状态，由`inst_addr_ok`信号指示其是否就绪。因此，对于某些特殊情况下出现的转顺即逝的信息，比如流水线刷新等，需要构建状态机缓存信息。待取指方向确认，且`icache`就绪，`pfs`会置起`fetch_en`，紧接着`btb`、`icache`、`tlb`便会接收`pfs`发出的`fetch_pc`，开始相应的操作。
### `btb`
分支预测器，根据`PC`直接预测其跳转地址。32项`btb`组织为`CAM`表的形式，由`PC`查询。此外，还包括一个`ras`，组织为一个8项的栈，存储函数调用过程中的返回地址。`btb`分支预测的结果会在下一拍返回，若预测正确则可消除下一拍产生于`fs`级流水的空泡，预测错误不会造成任何性能损失。
### `icache`
指令缓存，两路组相连的结构。`fetch_pc`进入`icache`后，首先根据由`fetch_pc`拆解而来的`index`部分，索引出两路的`cache`行。其次再根据`tag`部分与`tlb`翻译得到的物理页号是否相等判断是否有命中项。若命中，下一拍返回`inst_rdata`，若未命中，则进入`icache`处理`miss`请求的状态机，`inst_addr_ok`拉低。等待`miss`请求处理完毕后再接收新的取指请求。替换策略为随机替换。
### `tlb`
组织为32项`CAM`表的形式，指令和数据共用，需要两个查询端口。通过`fetch_pc`的虚页号查询是否存在命中项，命中则返回物理页号。若未命中，则会标记该指令存在`tlb`缺失例外，并进入例外处理程序。待对应`tlb`项在页表中找到并由软件填入`tlb`后，重新执行该指令。
### `fs`
`fs`取值级便是真正意义上的第一级流水。`fs`级接收`icache`返回的指令码`inst_rdata`，由`inst_data_ok`指示指令码是否就绪。若`icache miss`，`fs`级便会阻塞。额外需要注意一点，`tlb`的读取有一拍的延迟，因为32项的CAM表会有较长的逻辑。因此`tlb`的读取结果是在`fs`级得到，也就表示`tlb`相关的例外判断是在`fs`级完成，而取指请求是在`pfs`级发出。所以`fs`级需要具备中止上一拍`pfs`级发往`icache`的取指请求的能力，体现在`tlb_excp_cancel_req`信号中，`dcache`同理。
## 译码阶段
### `ds`
译码级，其功能便是将指令码解析为对应的操作码，并根据寄存器号，从`regfile`中取出寄存器值。不过寄存器的最新值可能还未被写入到`regfile`中，因为后续流水线中的指令正在执行，结果未获得或者未写回，而当前指令可能依赖于这些指令的结果。因此译码级与后续流水线构建了前递路径（`es_to_ds_forward_bus/ms_to_ds_forward_bus`），用于前递未写回的结果，或者通知`ds`级结果未获取，需要阻塞。此外，经过译码，已知晓该指令是否为跳转指令，以及是否跳转。也就可以识别分支预测器的预测结果是否正确，`ds`级便可通过`br_bus`对取指方向进行修正，以及更新分支预测器的历史信息。`btb`的预测包括两个方面，该`PC`是否为跳转指令；识别为跳转指令时是否跳转。`ds`级需要鉴别并对分支预测器执行特定的更新操作。
## 执行阶段
### `es`
执行级，根据译码得到的操作码，送往`alu`、`mul`、`div`进行特定类型的运算。`alu`用于处理较简单的运算，比如加减、移位运算。`mul`为华莱士树实现的乘法部件，拆为两级。`div`为常规的迭代除法部件，需要34个周期得到结果。此外，若为访存指令，执行级便可通过加减运算得到访存地址。同`pfs`等待`dcache`准备就绪，即`data_addr_ok`置起，`es`便可发出`data_fetch`以及`data_addr`，由`tlb`进行虚实地址映射以及`dcache`取回数据。不过需要注意若当前指令或者后续流水线中的指令存在例外，需要及时中止`data_fetch`的置起。
## 访存阶段
### `dcache`
数据缓存，在`icache`的基础上新增了处理写请求的能力。每个`cache`行新增一个`dirty`位，用于标识该`cache`行是否为脏，在被替换时判断是否需要写回。此外，写请求在命中的情况下，相较于读请求，需要额外的一拍将数据写入到`ram`中。这额外一拍的延迟可以通过构建写请求状态机节省。待确认写请求命中后，进入状态机，使得`dcache`可以继续接收新的请求。不过需要注意规避读写请求同时出现在单端口的`ram`上。
### `ms`
访存级，等待`dcache`数据返回，由`data_data_ok`指示`data_rdata`是否有效。`ms`级同`fs`级，需要由`tlb_excp_cancel_req`信号取消掉上一拍`es`发往`dcache`的访存请求。写请求不同于读请求需要等待接收数据，待请求发出后，不管命不命中，可继续向后流动。
## 写回阶段
### `ws`
写回级，此时指令已执行完毕，并得到`result`，需根据执行结果修改处理器状态，包括两个方面：写通用寄存器`regfile`以及状态寄存器`csr`；根据指令触发的例外类型，修改`csr`寄存器，以及清空流水线并调整取指方向至例外入口。
---
## 流水级间交互
最理想的情况下，同一时刻五个阶段都处于工作的状态，也就表示同一时刻在处理五条指令。此时，处理器核在通过流水线切分得到较高频率时，带宽仍然保持为1指令/拍。但在实际情况下，如前文所述，并不会如此，各级流水总是会出现阻塞的情况。因此，流水级之间需要交互，避免一级流水的操作还未完成便被上一级覆盖。
流水级之间的交互逻辑中，需要维护以下关键信号：
- `stage_valid`：由触发器维护，表示当前流水级是否在处理指令。
- `stage_ready_go`：表示流水级是否需要被阻塞。
- `stage_allowin`：表示当前流水级是否允许上一级流水进入，该信号传递至上一级，与上一级流水交互，两种情况下该信号置起，当前流水无正在处理的指令；或者当前流水级中的指令已处理完毕且下一级流水允许进入。该信号会由最后一级流水向前传递，只要某一流水级阻塞，其`stage_allowin`拉低，同一时刻，前面所有流水级的`stage_allowin`都会拉低（假设所有流水级中都有指令在处理）。
- `stage_to_nextstage_valid`：表示当前流水级中是否有处理完毕的指令，该信号传递至下一级，与下一级流水交互。下一级流水在收到高电平信号时，且其下一级流水的`stage_allowin`为高电平，则会在下一拍置起下一级流水的`stage_valid`，实现流水级间指令的流动。`stage_to_nextstage_bus`总线信号中传递缓存信号，会随着`stage_to_nextstage_valid`流动。
