            Bug ID: 310
           Summary: Function Units to cover multiple tasks
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net
          Reporter: lkcl at lkcl.net
                CC: libre-riscv-dev at lists.libre-riscv.org
   NLnet milestone: ---

* power_enum Function converts to unary values (1/2/4/8...)
* CSV files "Function" column sets multiple bits
* ALU / Logical / etc. (as appropriate) covers *MULTIPLE* operations
  (switch statements), with duplicated logic.

this gives parallel operations and more opportunities for operations
to wait in line.
