Abstract :
Due to the rapid expansion of the application areas of digital signal processing (DSP), various fast multiplication-and-accumulation (MAC) modules are required by system developers. In this paper, a high speed and random logic structure MAC design methodology is presented with Wallace trees and borrow-select subtracters (BSSs) as the architecture of the MAC. EDA tools can be utilized to perform automatic placement and routing. A 16*12 MAC and a complex 16*12 MAC with both real and imagine parts are designed by applying this methodology for a 1-million-transistor DSP chip. Simulation results of the modules in 0.6 μm CMOS technology are encouraging
