摘要
A VLSI implementation of a low-power DSP is described, which is dedicated to the G.723.1 low bitrate speech codec. A number of sophisticated DSP microarchitectures are devised mainly on dual multiply accumulators, rounding and saturation mechanisms, anti two-banked on-chip memory. The proposed DSP architecture has been integrated in the total area of 7.75 mm(2) by using a 0.35 mu m CMOS technology, which can operate at 10MHz with the dissipation of 45mW from a single 3V supply.
