Product details
Overview
ADSP-21565KSWZ8 from Analog Devices is a SHARC+ single-core floating-point DSP engineered for high-performance audio and signal processing in automotive and professional systems. It operates at up to 800 MHz, integrates 5 MB of L1 SRAM with parity, supports 32-/40-/64-bit floating-point arithmetic, and features hardware FIR/IIR accelerators running at core speed. It is used in automotive digital cockpit audio processing and ANC/RNC subsystems.
For engineers reviewing the ADSP-21565KSWZ8 datasheet, ADSP-21565KSWZ8 pinout, ADSP-21565KSWZ8 application, or ADSP-21565KSWZ8 equivalent, key selection criteria include its 800 MHz SHARC+ core speed, 5 MB L1 SRAM configuration, AEC-Q100 qualification, DDR3L interface capability, and dual ASRC/SPORT/DMA architecture for real-time multichannel audio routing.
Technical Context
The ADSP-21565KSWZ8 implements a SIMD SHARC+ core with two parallel processing elements (PEx and PEy), each equipped with ALU, multiplier, shifter, and register file - enabling true single-instruction, multiple-data execution on 32-/40-/64-bit floating-point data. Its memory subsystem includes four configurable L1 SRAM blocks (total 5 MB) with parity, supporting independent PM/DM bus accesses per cycle.
It integrates a dedicated SHARC fabric connecting FIR/IIR accelerators directly to L1 memory at CCLK speed, bypassing system fabric latency. The processor also includes a 32-entry instruction conflict cache, branch target buffer (BTB), and hardware circular buffer support via dual DAGs - all optimized for deterministic looped DSP kernels like filter banks and FFTs.
