Abstract :
A 0.4mm2 SoC resource manager controls operating frequency and allocates data bandwidth using various monitored information such as temperature, frequency of IP blocks and number of operations executed. Results show an increase of allowable temperature range by 30degC for real-time operations of two processor cores and two media processing cores. The design is fabricated in an 8M 90nm CMOS process
