Adding Hardware Accelerators to Reduce Power in Embedded Systems

Executive Summary

The rule of thumb in embedded system design has been that adding hardware increases power demands. The careful use of hardware accelerators, however, inverts the rule: adding hardware can reduce power. By analyzing algorithms and implementing appropriate accelerators in programmable logic, developers can increase a design's performance while reducing power consumption in an embedded computing system. Test results show that accelerators extend trade-off options from as much as 200-fold performance improvement for the same power to the same performance with a 90% power reduction.
