Abstract :
A 0.25 /spl mu/m CMOS 0.9 V 100 MHz 4 mW 2 mm/sup 2/ DSP core is composed of a 16 b multiplier, a 32 b adder, an 8 kb SRAM, and a PLL. Voltage-scalable circuits capable of operating at 0.5 V to 2.5 V and level-converting interface circuits applied to the DSP make it suitable for multiple-supply-voltage portable systems.
