-- Project
-- pAVR (pipelined AVR) is an 8 bit RISC controller, compatible with Atmel's
-- AVR core, but about 3x faster in terms of both clock frequency and MIPS.
-- The increase in speed comes from a relatively deep pipeline. The original
-- AVR core has only two pipeline stages (fetch and execute), while pAVR has
-- 6 pipeline stages:
-- 1. PM (read Program Memory)
-- 2. INSTR (load Instruction)
-- 3. RFRD (decode Instruction and read Register File)
-- 4. OPS (load Operands)
-- 5. ALU (execute ALU opcode or access Unified Memory)
-- 6. RFWR (write Register File)
-- Version
-- 0.32
