Imperas Software Ltd., the leader in RISC-V processor verification technology, announces the latest updates to riscvOVPsimPlus with support for the near ratified P extension and architectural validation test suites. The P (or Packed SIMD/DSP) extension is a significant addition to the flexibility of the modular RISC-V ISA (Instruction Set Architecture); it supports real-time data processing applications as part of the main processor pipeline without the need for the associated inefficiencies of a co-processor. For processor hardware verification, a basic test suite helps ensure implementations have a basic software level compatibility to the new P extension as a reference to the developers’ interpretation of the written specification.
