Energy per Instruction Trends in Intel® Microprocessors

چکیده
Energy per Instruction (EPI) is a measure of the amount of energy expended by a microprocessor for each instruction that the microprocessor executes. In this paper, we present an overview of EPI, explain the factors that affect a microprocessor’s EPI, and derive a historical comparison of the trends in EPI over multiple generations of Intel microprocessors. We show that the recent Intel® Pentium® M and Intel® CoreTM Duo microprocessors achieve significantly lower EPI than what would be expected from a continuation of historical

متن کاملPower Analysis and Instruction Scheduling for Reduced Di/dt in the Execution Core of High-performance Microprocessors
TOBUREN, MARK CHRISTOPHER. Power Analysis and Instruction Scheduling for Reduced di/dt in the Execution Core of High-Performance Microprocessors. (Under the direction of Dr. Thomas M. Conte.) Power dissipation is becoming a rst-order design issue in high-performance microprocessors as clock speeds and transistor densities continue to increase. As power dissipation levels rise, the cooling and r...
متن کاملEnhancing the Matrix Transpose Operation Using Intel Avx Instruction Set Extension
General-purpose microprocessors are augmented with short-vector instruction extensions in order to simultaneously process more than one data element using the same operation. This type of parallelism is known as data-parallel processing. Many scientific, engineering, and signal processing applications can be formulated as matrix operations. Therefore, accelerating these kernel operations on mic...
