            Bug ID: 359
           Summary: cut down on wires between decode and function units
           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: ---

subsets of decoded instructions are passed to function units.  unfortunately
the expansion of wires is vast.

a solution involves passing the instruction to each pipeline and having the
*FU* perform the decode... *at the FU*.

to do this, decode2 should take the subset of fields to be decoded, rather than
assiming that all fields should always be decoded.

this can be done dynamically.
