SHARC 2148x Digital Signal Processors
Formerly reserved for specialized systems with board space to accommodate multiple processors and off-chip memory, floating point processing is now more accessible and affordable for designers looking to bring high-end processing power to mass market applications. SHARC 2148x series processors deliver up to 33% greater performance (400MHz) and up to 250% more on-chip memory (5Mb) than competing 32-bit floating point DSPs, distinguishing the SHARC 2148x series as the processors of choice for high definition (HD) audio and home theater applications, as well as advanced industrial applications requiring single-chip, floating point precision at a low price point.

SHARC 2147x Digital Signal Processors
Designers of portable and/or battery-powered systems are now better equipped than ever to leverage floating point processing precision without compromising system power budgets, board space, or component costs. For portable devices and applications like advanced driver assistance systems (ADAS) that require floating point processing precision with low power consumption and high environmental tolerance, new 12x12mm SHARC 2147x series processors consume only 363 mW power (typical use-case) – up to 20% less power than competing processors – and deliver performance up to 266MHz with up to 5 Mb on-chip memory to provide more performance and memory integration per square millimeter than any other competing floating point DSP.
