Merge pull request #145 from zeldin/bigendian2
Update big endian instruction encoding

Marcus Comstedt 6c8e97f825 Update big endian instruction encoding
Between draft-20181101-ebe1ca4 and draft-20190622-6993896 of the
RISC-V Instruction Set Manual, the wording was changed from requiring
"natural endianness" of instruction parcels to require them to be
little endian.

Update the big endian instruction pipe to reflect the newer requirement.

Merge pull request #136 from zeldin/rv32e
Add support for RV32E in RegFilePlugin
2020-09-06 22:23:24 +02:00
Marcus Comstedt 8e466dd13c Add support for RV32E in RegFilePlugin
The RV32E extension removes registers x16-x31 from the ISA.  This
is useful when compiling with -mem2reg to save on BRAMs.  On iCE40
HX8K this option saves 1285 LC:s, which also improves the routing
situation, when using -mem2reg.

Note that the illegal instruction exception required by the RV32E
specification for accesses to registers x16-x31 is not implemented.
