[Show abstract][Hide abstract] ABSTRACT: 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.
[Show abstract][Hide abstract] ABSTRACT: Many emerging and future applications require significant levels of complex digital signal processing and operate within limited power budgets. Moreover, dramatically rising VLSI fabrication and design costs make programmable and reconfigurable solutions increasingly attractive. the ASAP project addresses these challenges with a chip multiprocessor composed of simple processors with small memories, achieving high energy efficiency and throughput in a small chip area.
