Flow Computing in Finland has started alpha testing of a RISC-V compiler for its Parallel Processing Unit (PPU) AI block.
The PPU is capable of increasing any CPU architecture by up to 100X by using the compiler enables source code to take advantage of the architecture. The first target compilations have shown that the loops common in RISC-V CPU models can be significantly reduced by recompiling the existing code, reaching the 100X expected performance.
This compares to a 2x improvement without recompilation by simply replacing some CPU cores with PPUs with no change to the source code.
