Energy efficient DSP systems - architecture and algorithms issues

This paper presents some insights into the architecture of one of Texas Instrument´s (TI) most energy efficient digital signal processors (DSP), the TMS320C55x. It discusses key low-power architecture issues including the rationale used in making trade-offs that did not adversely affect performance while minimizing chip level power requirements. The paper also discusses some algorithm development centric issues to illustrate how algorithm level researchers can also contribute to the bottom line when it comes to decreasing power consumption of a DSP system.
