Overview

SHARC-FX Core Infrastructure

  • 800 MHz (max) Core clock frequency
  • 64/512 KB on-chip Level 1 (L1) Instruction/Data SRAM memory and (with ECC) increases low latency performance
  • 32/256 KB on-chip Level 1 (L1) Instruction/Data cache memory (with ECC)
  • 256-bit SIMD, 4-way VLIW with large register set
  • Fast on all datatypes: 32-way parallel int8 to 4-way float64
  • >4x per-cycle performance increase vs SHARC+® predecessor

Arm Core Infrastructure

  • 2x 1.2 GHz Arm Cortex-A55 (with Neon/FPU)
  • 32 kByte/32 kByte L1 Instruction/Data Cache per core
  • 256 kByte L2 Cache per core

Memory

  • 2048 KB on-chip Level 2 (L2) SRAM with ECC protection - eliminates need for external memory in many use cases
  • Level 3 (L3) interface optimized for low system power, providing 16-/32-bit interface to LPDDR4 devices

Product Details

The EV-SC846-SOM enables evaluation and rapid prototyping of designs featuring the ADSP-SC84x/2184x Family (ADSP-SC844/ADSP-SC846) of SHARC-FX audio processors. It provides an easy-to-use plug-n-play reference design with expansion capabilities to interface to custom hardware ahead of the release of the processor itself. When the EV-SC846-SOM board is plugged into the EV-SOMCRR2-EZKIT carrier board, the resulting EZ-KIT® evaluation system can be used for fast and easy evaluation of the processor core and system peripherals/interfaces.

The EV-SC846-SOM enables rapid prototyping for a wide range of applications, including immersive 3D sound and personal audio zones (PAZ), automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (ICC), engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). Additional applications include professional audio and soundbars / home AVRs (with 3D Object and Multi-Channel Audio) and enhanced conferencing systems. ADI offers several software modules (e.g., AEC/NR, microphone beamforming, pitch shifting, harmonic generators, wave players, etc.), as well as complete software solutions that can be licensed, where users can develop/evaluate their audio and voice processing applications. ADI also offers 3rd party surround sound solutions that can be licensed on ADI’s SHARC processor families. Please visit ADI’s Software Solutions page for more information.

The EV-SC846-SOM module utilizes the CrossCore® Embedded Studio (CCES) development tools to enable developers to achieve faster time to market. The development environment aids advanced application code development and debug, such as:

  • Create, compile, assemble, and link application programs written in C++, C, and assembly
  • Load, run, step, halt, and set breakpoints in application programs
  • Read and write data and program memory
  • Read and write core and peripheral registers
