Description

Reaching speeds of up to 1 GHz, the ADSP-2156x processors are members of the SHARC®family of products. The ADSP-2156x processor is based on the SHARC+®single core. The ADSP-2156x SHARC processors are members of the SIMD SHARC family of digital signal processors (DSPs) that feature Analog Devices, Inc., Super Harvard Architecture. These 32-bit/40-bit/64-bit floating-point processors are optimized for high performance audio/floating-point applications with large on-chip static random-access memory (SRAM), multiple internal buses that eliminate input/output (I/O) bottlenecks, and innovative digital audio interfaces (DAI). New additions to the SHARC+ core include cache enhancements and branch prediction, while maintaining instruction set compatibility to previous SHARC products.By integrating a rich set of industry-leading system peripherals and memory (see Table 1 in the data sheet), the SHARC+ processor is the platform of choice for applications that require programmability similar to reduced instruction set computing (RISC), multimedia support, and leading edge signal processing in one integrated package. These applications span a wide array of markets, including automotive, professional audio, and industrial-based applications that require high floating-point performance.APPLICATIONSAutomotive:audio amplifier, head unit, ANC/RNC, rear seat entertainment, digital cockpit, ADASConsumer & Professional Audio:speakers, sound bars, AVRs, conferencing systems, mixing consoles, microphone arrays, headphones
