Analog Devices, Inc. (ADI), Analog Devices today announced four fixed-point digital signal processors (DSPs) certified for automotive applications. Designed to meet the emerging market needs of new optimized audio algorithms, the ADAU1466 and DAU1467 SigmaDSP ® processors feature market-leading fixed-point DSP processor performance with three times the internal program memory of the previous generation and the internal data memory. Double the product of the first generation. Let's take a look at the related content with the car electronics editor.

The ADAU1463 and ADAU1467 are available in an 88-lead LFCSP package with eight pins that can be configured for serial data input or output. These additional pins provide greater flexibility in amplifier or audio host designs to support applications such as hands-free, active noise cancellation, and acoustic noise reduction. Like all SigmaDSP ® processors, the ADAU1463 and ADAU1467 also feature a unique hardware architecture optimized for efficient audio processing. Its Quadruple Multiply Accumulate Plus (MAC) architecture includes audio-specific hardware accelerators that optimize MIPS performance for latency-sensitive applications. The ADAU146x family uses ADI's award-winning SigmaStudio TM graphical programming tool to quickly develop and tune signal streams and applications with minimal learning time.
Compared to other DSP devices, the ADAU146x family offers unparalleled parallel processing performance, flexibility and system scalability. The cost-effective 150 MHz and 300 MHz DSP cores give system designers an alternative to traditional applications and demanding applications. The 300 MHz DSP core delivers up to 1.2 GMAC performance with 6,144 instructions at 48 KHz audio sample rate. It offers a built-in stereo asynchronous sample rate converter (ASRC) and an audio signal routing matrix. The on-chip RAM is twice as large as the previous generation DSP, allowing flexible and simple execution of demanding algorithms. The integrated PLL and flexible clock generator hardware can simultaneously generate up to 15 audio sample rates.
The energy-efficient ADAU146x family of cores performs a complete signal flow with power consumption of only a few hundred mW and consumes less than one watt (25°C) at the highest program load. The ADAU146x DSP is an ideal replacement for larger, more costly, general-purpose DSPs that consume more power when performing similar processing. With a highly configurable serial port, S/PDIF interface, multi-purpose input/output pins, and 10-bit auxiliary ADC, the ADAU146x DSP interfaces with a wide variety of audio devices such as ADCs, DACs, digital audio devices, amplifiers, and other controls. The circuit also significantly reduces system complexity.
