Scalar Fixed-Point Compliancy Subset (SFS)

Goals

  • Add support for the SFS subset of PowerISA v3.1
  • Provide a usable framework for CPU verification

Roadmap

Testbench

  • Define the Power-FV CPU interface (7114ed80)
    • CIA/NIA
    • GPRs (todo: quad-word access)
    • CR
    • SPRs
    • Instruction/data memory
    • Interrupts
  • Add support for alternative arithmetic operations (to serve as substitutes for mul/div ops) (a325393c)

Checks
