Energy consumption is a critical design issue in real-time systems, especially in batteryoperated systems. Maintaining high performance, while extending the battery life between charges is an interesting challenge for system designers. Dynamic Voltage Scaling and Dynamic Frequency Scaling allow us to adjust supply voltage and processor frequency to adapt to the workload demand for better energy...

data flow VLSI processor ImPPs( Image Pipelined Processor :pPD7281). lmPP capable of performing 5 million instructions per second(5 MIPS), so TIP-4 has maximum processing speed of 2560 million instructions per second(2. 5GIPS) The prototype system TIP-4P that has actually been developed has 64 ImPPs, thus the peak computation rate for TIP-4P is 320 MIPS. To use 512 ImPPs efficiently. TIP-4 has ...
