The fourth generation DSP allows the ability to connect to faster external memory by providing a glueless interface to 16-bit wide DDR2 SDRAMs.įourth-generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. There is a new feature called Variable Instruction Set Architecture (VISA) that allows the code size to be decreased by 20% to 30% and increase the memory size availability. In addition to its higher core performance, the ADSP-21469 includes additional processing blocks such as FIR, IIR, and FFT accelerators to increase the total performance of the system. This level of performance makes the ADSP-21469 particularly well suited to address the increasing requirements of the professional and automotive audio market segments. The ADSP-21469 offers the highest performance – 450 MHz/2700 MFLOPs - within the fourth generation SHARC Processor family.

These newest members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications. All devices are pin-compatible with each other and completely code-compatible with all prior SHARC Processors.

The fourth generation of SHARC ® Processors, which includes the ADSP-21469, offers increased performance, hardware-based filter accelerators, audio and application-focused peripherals, and new memory configurations capable of supporting the latest surround-sound decoder algorithms.
