The RV12 is a highly configurable single-issue, single-core RV32I, RV64I compliant RISC CPU intended for the embedded market. The RV12 is a member of the Roa Logic’s 32/64bit CPU family based on the industry standard RISC-V instruction set
The RV12 implements a Harvard architecture for simultaneous instruction and data memory accesses. It features an optimizing 6-stage pipeline, which optimizes overlaps between the execution and memory accesses, thereby reducing stalls and improving efficiency.
Optional features include Branch Prediction, Instruction Cache, Data Cache, and Debug Unit. Parameterised and configurable features include the instruction and data interfaces, the branch-prediction-unit configuration, and the cache size, associativity, and replacement algorithms. Providing the user with trade offs between performance, power, and area to optimize the core for their application.
