To take advantage of the growing opportunities in Smart Metering and other energy-control applications, developers need to be able to add communication links to existing systems in a cost-effective manner. TI’s innovative Viterbi Complex Math Unit (VCU), introduced to the real-time control TMS320C2000 microcontroller (MCU) platform, provides an enhanced math engine that accelerates complex communications algorithm processing by a factor of up to 7x. This white paper provides an overview of how the VCU adds system efficiency and performance that complements the TMS320C28x DSP core, including key operation examples, benchmarks and architecture benefits.
