Low power application specific processor for ISM band transceiver

A low power integrated transceiver incorporating a full Industrial Scientific Medical (ISM) band low IF transmitter and receiver with an application specific RISC processor design is described. The RISC processor contains hardware acceleration blocks, including parallel-to-serial, timers, 8B10B endec and an AES cryptographic accelerator. Application specific microcode allows the device to be tailored for different applications through a single custom mask. The design is fabricated on 0.18um CMOS. Measurements and results from prototype silicon are presented.
