A new high performance digital signal processor (DSP) that lowers power consumption, reduces chip count, and enables system cost savings for wireless communications applications was developed. The new device contains high performance, hard-wired functionality with a specialized instruction set to effectively implement the worldwide digital cellular standard algorithms, including GSM, PDC and NADC, and also features both full rate and future half rate processing by software modules. The device provides a wider operating voltage ranging from 1.5 V to 5.5 V using 5 V process based on the market requirement of 5 V supply voltage, even though a power supply voltage in most applications will be shifted to 3 V. Several circuits was newly developed to achieve low power consumption and high speed operation at both 5 V and 3 V process using the same data base. The device also features over 50 MIPS of processing power with low power consumption and 100 nA stand-by current at either 3 V or 5 V. One remarkable advantage is a flexible CPU core approach for the future spin-off devices with different ROM/RAM configurations and peripheral modules without requiring any CPU design changes. This paper describes the architecture of a lower power and high speed design with effective hardware and software modules implementations.
