SI-AM572xDSP
SI-DM816xDSP-EPIC board
A powerful Sitara Multicore ARM + Digital Signal Processor (DSP) carrier card with PCI Express expansion.

Description

The SI-AM572xDSP from Sheldon Instruments is an ARM plus Digital Signal Processor (DSP) carrier card with PCIe-104 expansion that may run Linux and be a C programmable platform intended for low power environments that require intensive computing in a cost sensitive solution.

Sitara devices supported on the SI-AM572xDSP card:
AM5728DSP
AM5726DSP

The SI-AM572xDSP is a Small Form Factor (SFF) family of Commercial Off the Shelf (COTS) carrier cards featuring the powerful Sitara AM572x ARM plus DSP video processor from Texas Instruments. The TI AM572x devices are multicore ARM + DSP System on Chip (SoC) able to run Linux or Android OSes, making for an ideal host carrier platform with PCIe-104 expansion.

There are separate ARM and DSP subsections, with the ARM subsection consisting of a pair of Cortex A15 cores clocked at 1.5GHz, and with the DSP subsection consisting of a pair of C66x VLIW cores clocked at 750MHz. All of this is attained at less than 8 watts of power consumption while most processors of this caliber are in the 60W range.

Applications

  • Video Encode, Decode, Transcode, and Transrate
  • Video Security and Infrastructure
  • Real Time Image Processing
  • Machine Vision
  • Unmanned Aerial Vehicle Control Systems
  • Industrial Control and Automation
  • Medical Imaging
  • Military and Aerospace
  • Test and Measurement


Block Diagram


The SI-AM572xDSP is available with extensive development tools from Sheldon Instruments and TI’s Code Composer Studio Integrated Development Environment (CCS) that include the Reference Design Kit (RDK) for both the ARM side as well as the DSP side.

Host and ARM Side Tools
For the ARM or host side, Sheldon Instruments provides:

  • Linux 2.6, U-Boot, Root File System, Tool Chain, and NAND flash programming utility.
  • Sheldon Instruments projects and related source code available for application development and system integration.

DSP Side Tools
For the DSP side, Sheldon Instruments provides various TI CCS projects, both compiled versions for quick loading with the ARM side sample program, along with complete projects and related source code. These DSP projects include:

  • A bare low-level runtime initializer to demonstrate how to setup DSP entry points.
  • A project to demonstrate TI SYS/Bios usage and initialization.
  • Various projects to demonstrate initialization and usage of the ARM and DSP system components. In particular, configuration of the DDR3 modules, Ethernet, and EDMA3 transfers.
