Abstract(in English) | This article presents a method of synthesizing hardware from RISC-V binary codes. RISC-V is an open source instruction set architecture, where several CPU designs are provided under BSD licenses. Binary synthesis, a variant of high-level synthesis, can auto-generate hardware from assembly programs or inline assembly codes, and can be used to synthesize interrupt handler written in assebmly language into hardware. This article presents the first binary synthesizer which takes an executable binary codes for RV32IM and synthesizes a hardware module which is functionally equivalent with a CPU that runs the code. A CDFG is generated from a linked executable binary code, from which an RTL description is generated by the conventional high-level synthesis flow. This method can incorporate custum instructions into the synthesis flow, provided they are executed in fixed cycles and the execution units for them are separately designed from the CPU's datapath. From small scale codes consisting of less than 160 instructions, a prototype synthesizer has generated smaller and faster hardware modules than a Rocket Chip. A code containing SIMD add-saturate instruction has been also synthesized to accelerate the resulting hardware. |
