Abstract :
We describe a 16×16+32 bit Multiplication ACcumulator (MAC) design, PKU_MAC16_001, which has a design flow adaptable to technology portability. A router, R-RS001, is also developed to finish the layout routing. The booth2 algorithm in decoding and the 4-2-compressor as the compress tree structure are used in the MAC design. A top down custom digital design flow is adopted to realize the MAC. Finally, the layout is routed through R-RS001, which can do the most time consuming and tedious layout works in MAC design, making it much easier to move a design to new technology.
