Latest Vision DSP targeted at always-on and smart sensor applications

The Cadence® Tensilica® Vision P1 DSP is the latest addition to the Vision DSP family. The smallest Vision DSP is targeted for lower power, always-on application offering one-third the power and area compared to the highly successful Vision P6 DSP while offering an easy software transition from Vision P6 DSP via the N way programming model. The Vision P1 DSP also offers flexibility to configure without various features to reduce area and even reduce the data RAM to provide the best area for sensor integration.
