内核微架构可将两条指令融合为一条内部指令,这样其执行就不需要 10 个时钟周期。RISC-V 微架构自动对一些代码序列进行融合,例如 indexed loads、load-pair 和 store-pair 指令,从而显著加快执行速度。更大的好处是,由于 FE310 支持“C”扩展,可以融合两条兼容的 16 位压缩指令,因而在代码和执行速度方面都具备优...
Wire<1> eset:开机时的重置信号 Wire<6> load_store_queue_emptyspace_receiver:从LSB获取空位信息(TODO!!!)。由LSB在上一个clock写入,在本clock即可获取当前空位信息。该信息为空位数量,CSU结合自己上一时刻是否issue了指令,可以判断出如果当前时刻如果issue指令,LoadStoreBuffer在下一时刻收到后能否正确部署。 Wi...

add what looks like a negative number. Recognizing that this is likely to lead to all sorts of human errors, a handy pseudo instruction is available: load immediate orli. This is translated by the assembler into the correct pair of lui and addi instructions. So, our load now goes like ...
register in the pair is even-numbered), or on the stack by value if none is available. After a variadic argument has been passed on the stack, all future arguments will also be passed on the stack (i.e. the last argument register may be left unused due to the aligned register pair ...
Thus, when an instruction pair is effectively atomic, no other processor can change the value between the pair of instructions.In RISC-V this pair of instructions includes a special load called a load-reserved doubleword (1 r. d) and a special store called a store-conditional doubleword (...
Load/Store Pair for RV32 Fast-Track Extension (Zilsd & Zclsd) This extension adds support for loads and stores using aligned register pairs. It is an RV32-only extension, reusing existing RV64 encodings. License This work is licensed under a Creative Commons Attribution 4.0 International Licens...

SelectionDAG will not reassociate adds to the end of a chain if there are multiple users of later additions. This prevents isel from folding the immediate into a load/store address. One easy way to...
The__riscv_v_min_vlenmacro expands to the minimal VLEN, in bits, mandated by the available vector extension, if any. The value of__riscv_v_min_vlenis defined by the following rules: 128, if theVextension is present; 32, if one of theZve32{x,f}extensions is present; ...
