The MityDSP-L138 is a highly configurable, very small form-factor system on module that features a Texas Instruments OMAPL138 ARM+DSP SoC. The OMAPL138 features a 456 MHz ARM Applications Processor paired with a 456MHz Floating Point C674x DSP core. The module features FLASH (NAND, and NOR) and mDDR2 RAM memory subsystems, and a rich set of peripherals. The design of the MityDSP-L138 allows end users the capability to develop program images for the ARM processor and the DSP. The MityDSP-L138 provides a complete and flexible digital processing infrastructure necessary for the most demanding embedded applications development.

The OMAPL138 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, QNX and Windows XP embedded. SO-DIMM-200 (DDR2 Connector).

In addition to the ARM MPU, the OMAPL138 also includes the C674x DSP core from Texas Instruments. This DSP core is optimized for both fixed point and floating point calculations. A shared memory interface between the ARM and the DSP facilitate inter processor communications.

The primary interface to the MityDSP-L138 is through a standard SO-DIMM-200 card edge interface. The interface provides power, synchronous serial connectivity, and a rich set of interfaces available for application defined interfacing. Details of the SO-DIMM-200 connector interface are included in the SO-DIMM-200 Interface Description in the datasheet.
