Analog Devices SHARC® Processors dominate the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. ADI SHARC Processors bring floating-point processing performance to applications where dynamic range is key. SHARC Processors are based on a Super Harvard architecture that balances exceptional core and memory performance with outstanding I/O throughput capabilities. This Super Harvard architecture extends the original concepts of separate program and data memory busses by adding an I/O processor with its associated dedicated busses. In addition to satisfying the demands of the most computationally intensive, real-time signal-processing applications, SHARC processors integrate large memory arrays and application-specific peripherals designed to simplify product development and reduce time to market. SHARC processors provide a common set of features and functionality useable across many signal processing markets and applications. This baseline functionality enables the SHARC user to leverage legacy code and design experience while transitioning to higher-performance, more highly integrated SHARC products.
