The audio processing algorithms support a seamless combination of stream processing (sample by sample), multirate processing, and block processing paradigms. The restructured hardware architecture is optimized for efficient audio processing. They are pin and register compatible with each other, as well as with the ADAU1450/ADAU1451/ADAU1452 SigmaDSP processors. The ADAU1462/ADAU1466 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP ® devices. Other peripherals such as SPI,UART and Two-Wire Interface are routed through a Digital Peripheral Interface (DPI).
#Active sound control serial#
The fourth generation SHARC allows data from the serial ports to be directly transferred to external memory by the DMA controller.

Peripherals connected through the SRU include but are not limited to serial ports, IDP, S/PDIF Tx/Rx, and an 8-Channel asynchronous sample rate converter block. The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Grouped together, and broadly named the Digital Applications Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The fourth generation DSP allows the ability to connect to external memory by providing a glueless interface to 16-bit wide SDR SDRAMs.įourth-generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market.
#Active sound control code#
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 high core performance, the ADSP-21489 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-21489 particularly well suited to address the automotive audio and industrial control segments.

The ADSP-21489 offers the highest performance–450 MHz/2700 MFLOPs–in an LQFP package within the fourth generation SHARC Processor family. These newest members of the fourth generation 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 SHARC ADSP-21489 is one of two new members of the fourth generation of SHARC ® Processors that now includes the ADSP-21483, ADSP-21486, ADSP-21487, ADSP-21488, ADSP-21489 and 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.
