Subject: what is the "VPU" (in igen/cgen/sim) ?
Date: Tue, 23 Jun 2015 19:55:00 -0000 [thread overview]
Message-ID: <20150623195531.GJ17734@vapier> (raw)
[-- Attachment #1: Type: text/plain, Size: 735 bytes --]
the simulator had VPU tracing support proposed here:
https://sourceware.org/ml/gdb/2001-02/msg00267.html
and committed here:
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=01816cd804ec526927f53f0e408dae8c6ea269f2
but nowhere can i seem to find a description of what the "VPU" actually is.
the references to cgen doesn't lead anywhere as a grep of the cgen tree doesn't
match anything. the only user in the sim tree is msp430, and it uses it for
generic cpu register tracing. i would guess that it means "video processing
unit" as Google would lead me to believe, but that doesn't make sense in the
cgen/sim context. same for "virtual processing unit".
can anyone shed some light on this ?
