Dsp

Does E300 support DSP instructions? Does the riscv toolchain have optimized DSP libraries (like what ARM is doing with CMSIS)?

Regards

Hi, the current E3 Coreplex used in the E300 platform supports both single and double-precision floating-point, including fused multiply-add, as options. There currently is no standard fixed-point DSP support, but this could be added as custom instructions.
