Abstract :
A 26 mW 6.4 GFLOPS multi-core stream processor for mobile applications is implemented in 90 nm CMOS technology. A unified stream processing architecture with power-aware frequency scaling and adaptive task scheduling techniques are proposed to reduce the power consumption and increase the performance to achieve the performance of 200 Mvertices/s and 400 Mpixels/s in 3D graphic applications.
