5x power efficient SHARC DSP SOCs from ADI

Analog Devices (ADI) has released a new SHARC DSP SOC chips which is five times more power efficient than the present SHARC processor, and also ADI claims it is 2X more power efficient than the nearest competitor mostly a Freescale's one or a Texas Instruments' DSP.

The eight new SHARC processors offer a processing performance of 24 giga-floating-point operations per second using two enhanced SHARC+ cores and advanced DSP accelerators (FFT, FIR, IIR). When it comes to power consumption ADSP-SC58x and ADSP-2158x series consume less than 2 watts at high temperature, making this chip less dependent on cooling fans for thermal dissipation of heat, so that the systems can be more reliable and less noisy.

Applications suggested by ADI covers automotive, consumer and professional audio, multi-axis motor control, and energy distribution systems.

Along with the SHARC+ cores and DSP accelerators, ADSP-SC58x feature ARM Cortex-A5 processor, with FPU and Neo DSP extensions to handle additional real-time processing tasks and manage peripherals used to interface to time-critical data in audio, industrial closed-loop control, and industrial sensing applications. Interfaces include Gigabit Ethernet (with AVB and IEEE-1588 support), USB High-Speed, mobile storage (including SD/SDIO), PCI Express.

The ADSP-2158x family without ARM Cortex-A5 core targeted for applications where a DSP co-processor is typically needed and includes the two SHARC+ cores and DSP accelerators with a peripheral set matched to the cores.

ARM TrustZone security and an onboard crypto hardware accelerators are included for security enhancement. Memory parity and error-correction hardware provide higher data integrity to ensure higher reliability of the chip.

As usual, from sample procurement to reference designs to online support, ADI is offering full-fledged support immediately for this family of DSP SOC chips. Product samples and full set of development tools are immediately available.
