This page contains statistics of the the various implementations of the core.
It is split up into a section for each pipeline.
Feel free to add your own implementation results, but note the following, where possible:
- the commit for the core last synced to
- the commit of the SoC last synced to
- the version of the EDA tools
- the frequency the core was synthesised at
- the parameters on the core instantiation
- the FPGA "logic" (LUT) count and flop count (this differs between vendors, but give us an idea)
At commit 3e1de595ea8adcdd75edfb7cc748eadddafee168 of mor1kx and 4a14b6b581372926230ffa3733c301edb0a0b94c of mor1kx-dev-env.
Synthesised at 50MHz on Altera Cyclone IV with Quartus 12.1sp1
The the following parameters on the mor1kx-dev-env:
mor1kx
#(
.OPTION_CPU0 (MOR1KX_CPU0_OPTION_CPU),
.FEATURE_INSTRUCTIONCACHE ("NONE"),
.FEATURE_DEBUGUNIT ("ENABLED"),
.FEATURE_CMOV ("ENABLED"),

.OPTION_SHIFTER ("SERIAL"),
.FEATURE_MULTIPLIER ("THREE_STAGE"),
.FEATURE_DIVIDER ("SERIAL"),
.OPTION_PIC_TRIGGER ("LATCHED_LEVEL"),
.OPTION_RESET_PC (32'hf0000100)
