Exploiting Fixed Programs in Embedded Systems: A Loop Cache Example

Instruction caches have traditionally been used to improve software performance. Recently, several tiny instruction cache designs, including filter caches and dynamic loop caches, have been proposed to instead reduce software power. We propose several ...

Adding a small loop cache to a microprocessor has been shown to reduce average instruction fetch energy for various sets of embedded system applications. With the advent of core-based design, embedded system designers can now tune a loop cache ...

Energy consumption is a major concern in many embedded computing systems. Several studies have shown that cache memories account for about 50% of the total energy consumed in these systems. The performance of a given cache architecture is largely ...
