Forum: FPGA, VHDL & Verilog PacoBlaze: execution time for one instruction

Hello @all,

Does somebody know if the PacoBlaze needs exactly two clock cycles per
instruction? Just as PicoBlaze does.

Wiki http://en.wikipedia.org/wiki/PacoBlaze doesn't mention it.

Hello Daniel,
here ( http://bleyer.org/pacoblaze/ ) - referenced by the wiki - the
author of pacoblace writes: "... PacoBlaze tries to be as configurable
as possible, maintaining source code compatibility and code cycle
accuracy with the original PicoBlaze."

I guess "source code compatibility" in this context means that the
instantiation of the uC core "looks" the same as with PicoBlaze.

"code cycle accuracy" this is important :)
