With technology scaling to nanometer dimensions, leakage (static) power is gaining a bigger share in total power consumption, and furthermore, variation is increasing in transistor parameters (such as gate length, width, and threshold voltage, V<sub>th<\/sub> ) such that leakage as well as delay varies even among SRAM cells located within the same die.<\/p>\n<p>We present our recent research activities and results on reducing cache leakage energy under real-time constraints in processor-based embedded systems. This includes \/(i)\/ reducing leakage energy in instruction cache by taking advantage of value-dependence of SRAM leakage due to within-die V<sub>th<\/sub> variation, \/(ii)\/ using asymmetric SRAM designs that leak less when storing a 0, and then renaming register-operands of instructions so as to increase number of zeros in instruction-cache, and hence, to reduce leakage,\/ (iii)\/ shifting the delay-distribution curve of SRAM cells toward higher delays without impacting delay, capacity, or timing-yield of the entire cache by adding extra cache-ways or by adding spare rows\/columns of SRAM.<\/p>\n<p>We also briefly review our other works in Kyushu University on estimating and reducing static and dynamic power consumption of real-time embedded systems and also overview our methodology developed in Sharif University of Technology for efficient hardware-software implementation of object-oriented embedded applications<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Energy consumption is a fundamental barrier in taking full advantage of integration capability of today and future semiconductor manufacturing technology.
