AsAP: An Asynchronous Array of Simple Processors

An array of simple programmable processors is implemented in 0.18 mum CMOS and contains 36 asynchronously clocked independent processors. Each processor occupies 0.66 and is fully functional at a clock rate of 520-540 MHz at 1.8 V and over 600 MHz at 2.0 V. Processors dissipate an average of 32 mW under typical conditions at 1.8 V and 475 MHz, and 2.4 mW at 0.9 V and 116 MHz while executing applications such as a JPEG encoder core and a fully compliant IEEE 802.11 a/g wireless LAN baseband transmitter.
