The onboard OMAP-L138 processor provides a dual CPU core topology. The OMAP-

L138 includes an ARM926EJ-S micro-processor unit (MPU) capable of running the rich

software applications programmer interfaces (APIs) expected by modern system

designers. The ARM architecture supports several operating systems, including Linux

and Windows Embedded CE. In addition to the ARM core, the OMAP-L138 also

includes a TMS320C674x floating point digital signal processing (DSP) core. The DSP

core supports the freely provided TI DSP/BIOS real-time kernel. Users can leverage the

DSP to execute real-time compute algorithms (codecs, image/data processing,

compression techniques, filtering, etc.)

Figure 1 MityDSP-L138F Block Diagram

Figure 1 provides a top level block diagram of the MityDSP-L138F processor card. As

shown in the figure, the primary interface to the MityDSP-L138F is through a standard

SO-DIMM-200 card edge interface. The interface provides power, synchronous serial

connectivity, and up to 96 pins of configurable FPGA I/O for application defined

interfacing. Details of the SO-DIMM-200 connector interface are included in the SO-

DIMM-200 Interface Description, as shown below.

FPGA Bank I/O

The MityDSP-L138F provides 96 lines of FPGA I/O directly to the SO-DIMM-200 card

edge interface. The 96 lines of FPGA I/O are distributed across 2 banks of the FPGA.

These I/O lines and their associated logic are completely configurable within the FPGA

at the end user’s discretion.

With the Xilinx Spartan-6 series FPGA, up to the XC6SLX45, each of the user controlled

banks may be configured to operate on a different electrical interface standard based on

input voltage provided at the card edge connector. The banks support 3.3V, 2.5V, and

1.8V standard CMOS switching level technology. In addition, the I/O lines from the

FPGA have been routed as differential pairs and support higher speed LVDS standards as

well as SSTL 2.5 switching standards. Various forms of termination (pull-up/pull-down,

digitally controlled impedance matching) are available within the FPGA switch fabric.

Refer to the Xilinx Spartan 6 user’s guide for more information.

OMAP-L138 mDDR2 Memory Interface

The OMAP-L138 includes a dedicated DDR2 SDRAM memory interface shared between

the onboard ARM and DSP cores. The MityDSP-L138F includes up to 256 MB of

mDDR2 RAM integrated with the OMAP-L138 processor. The bus interface is capable

of burst transfer rates of 600 MB / second. Note that the OSCIN frequency to the OMAP-

L138 processor on the module is 24MHz.

OMAP-L138 SPI NOR FLASH Interface

The MityDSP-L138F includes 8 MB of SPI NOR FLASH. This FLASH memory is

intended to store a factory provided bootloader, and typically a compressed image of a

Linux kernel for the ARM core processor.

EMIFA - FPGA / NAND FLASH Interface

The OMAP-L138 and the Spartan-6 FPGA are connected using the DSP Asynchronous

External Memory Interface (EMIFA). The EMIFA interface includes 3 chip select

spaces. The EMIF interface supports multiple data width transfers and bus wait state

configurations based on chip select space. 8, and 16 bit data word sizes may be used.

Two of the three chip select lines (CE2, CE3) are reserved for the FPGA interface. The

MityDSP-L138F also includes 4 lines between the FPGA and the OMAP for the purposes

of generating interrupt signals.

In addition to the FPGA, up to 512 MB of on-board NAND FLASH memory is

connected to the OMAP-L138 using the EMIFA bus. The FLASH memory is 8 bits wide

and is connected to third chip select line of the EMIFA (CE1). The FLASH memory is

typically used to store the following types of data:

ARM Linux / Windows Embedded CE / QNX embedded root file-system

FPGA application images

runtime DSP or ARM software

runtime application data (non-volatile storage)

OMAP-L138 Camera and Video Interfaces

The OMAP-L138 includes an optional video port I/O interface commonly used to drive

LCD screens as well as a camera input interface. These interfaces have been routed to

the FPGA, which may be routed to the FPGA output pins on the SO-DIMM-200

connector. By routing the video data through the FPGA, additional user customization

and/or processing (e.g., overlays of video output, preprocessing or filtering of camera

input) may be offloaded from the OMAP-L138 to the FPGA for computation intensive

applications.

Debug Interface

Both the JTAG interface signals for the FPGA and the JTAG and emulator signals for the

OMAP-L138 processor have been brought out to a Hirose header that is intended for use

with an available Critical Link breakout adapter. This header can be removed for

production units; please contact your Critical Link representative for details.

This adapter is not included with individual modules but is included with each Critical

Link Development Kit that is ordered. If an adapter, Critical Link (CL) part number

80-000286, is needed please contact your Critical Link representative.

Software and Application Development Support

Users of the MityDSP-L138F are encouraged to develop applications and FPGA

firmware using the MityDSP-L138F hardware and software development kit provided by

Critical Link LLC.

The development kit includes an implementation of an

OpenEmbedded board support package providing an Angstrom based Linux distribution

and compatible gcc compiler tool-chain with debugger. In addition, the development kit

includes support libraries necessary to program the DSP core using the TI Code

Composer Studio DSP compiler tool-chain.

To support rapid FPGA and applications development, netlist components - compatible

with the Xilinx ISE FPGA synthesis tool – for commonly used FPGA designs and a

corresponding set of Linux loadable kernel modules and/or DSP interface APIs are

included.

The libraries provide the necessary functions needed to configure the

MityDSP-L138F, program standalone embedded applications, and interface with the

various hardware components both on the processor board as well as a custom

application carrier card. The libraries include several interface “cores” – FPGA and DSP

software modules designed to interface with various high performance data converter

modules (ADCs, DACs, LCD and touchscreen interfaces, etc) – as well as bootloading

and FLASH programming utilities.

Growth Options

The OMAP-L138 has been designed to support several upgrade options. These options

include various speed grades, memory configurations, and operating temperature

specifications including commercial and industrial temperature ranges. The available

options are listed in the section below containing ordering information. For additional

ordering information and details regarding these options, or to inquire about a particular

configuration not listed below, please contact a Critical Link sales representative.
