Analog Devices advances its SHARC Processor Platform to enhance Audio Systems Applications cost-effectively

Analog Devices adds ADSP-SC57x and ADSP-2157x processors Analog Devices adds ADSP-SC57x and ADSP-2157x processors to its series of single-chip multicore SHARC processors to advance audio experience and deliver cost-effective and reliable audio systems.

Combining Analog Devices’ SHARC technology with an ARM Cortex-A5 processor, is touted to provide a high performance, low cost, single-chip solution for complex applications involving the latest three-dimensional audio surround or advanced active noise cancellation algorithms with performance remaining for further audio post-processing.

With the ADSP-SC57x processors, the SHARC+ cores and the DSP accelerators provide real- time performance while the ARM Cortex-A5 processor handles connectivity and system operation. The ARM NEON engine provides additional signal processing capability if needed. These features are coupled with the latest interface technology including Gigabit Ethernet AVB, MLB for MOST150, CAN 2.0B, USB2.0 and mobile storage, which are all managed independently by the ARM processor and provide optimal flexibility in system design from a common product series.

With growing demand for increasingly complex audio algorithms in automotive and consumer applications, such as multi-channel audio decode and active noise cancellation, the ADSP-2157x series is designed for applications for which only a DSP is needed and includes two SHARC+ cores, a DSP-centric peripheral set and computational accelerators providing scalable performance with ARM and single- or dual-SHARC+ DSP variants in two package options.

Reducing the industry concerns around software IP protection, the new processors are said to include ARM TrustZone security, integrated cryptographic hardware accelerators and secure OTP memory.

The ADSP-SC57x and ADSP-2157x processors are supported by Analog Devices’ award-winning CrossCore Embedded Studio suite, providing design engineers with interactive, real-time development tools. Additionally, SigmaStudio support provides an extensive selection of optimized audio libraries with easy-to-use graphical audio development and tuning tools for faster time to market.

An optimized royalty free Ethernet AVB stack developed and supported by Analog Devices, AUTOSAR MCAL drivers, and many third-party algorithms and software components are available specifically for automotive applications.

Linux and Micrium RTOS support is also said to be available for the ADSP-SC57x processors.

Applications

Target applications include automotive premium audio, consumer and pro-audio, and industrial systems that require high floating-point performance.
