Subject: [libre-riscv-dev] [Bug 359] New: cut down on wires between decode and function units
Date: Sun, 31 May 2020 17:46:17 +0000
Message-ID: <bug-359-13@https.bugs.libre-soc.org/> (raw)
https://bugs.libre-soc.org/show_bug.cgi?id=359
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@lkcl.net
Reporter: lkcl@lkcl.net
CC: libre-riscv-dev@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.
