SI-AM572xDSP
SI-AM572xDSP-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 and optional FMC expansion ports 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, equipped with multiple I/O ports, making for an ideal host carrier platform with PCIe-104 expansion.

There are separate ARM, GPU, and DSP subsections, with the ARM consisting of a pair of Cortex A15 clocked at 1.5GHz, the GPU featuring a pair of SGX544 3D cores, and with the DSP consisting of a pair of C66x VLIW cores clocked at 750MHz.

As an industry first, a novel Programmable Real-Time Unit (PRU) consisting of a pair of Dual Cortex-M4 controllers are available as a powerful C programmable logic engine, similar to an FPGA. The great advantage of the ubiquitous C language significantly reduces the complexities of VHDL or Verilog languages required for programming FPGAs.

All of this is attained at less than 8 watts of power consumption while most processors of this caliber are in the 60W range.

High Speed Serial Interfaces: PCIe, GbE, & SATA
There are multiple standard high speed interfaces ranging from PCI Express Gen2, Gigabit Ethernet and SATA along with industrial interfaces such as UARTs and CANbus.

Hardware Expansion with PCIe-104 and PRU to FMC
There are two hardware expansion sites on the SI-AM572xDSP, with the first consisting of a PCIe-104 expansion site capable of stacking up to four (4) single lane PCIe-104 modules.

The second expansion site takes advantage of the Sitara’s novel Programmable Real-Time Unit that can be used as an FPGA substitute, complete with a myriad of multi-function customizable digital I/Os, with access to all internal device resources. The PRU lines are routed to an FPGA Mezzanine Card (FMC) expansion connector.

Flexible PCIe-104 and FMC expansion sites make it ideal for those who prefer to leverage a wide array of 3rd party industry standard modules, use their own custom hardware or simply update legacy designs with minimal effort.

Upgrades & Options
Upgrade options for the SI-AM572xDSP include various core and memory configurations, nonvolatile storage, and either commercial or expanded temperature ranges. A full line of software development tools are available from Sheldon Instruments and TI for Windows and Linux platforms.
