MityDSP-L138F – FPGA+DSP+ARM System on ModuleARM9, Floating Point DSP, and User Programmable FPGA SOM

Product status: End of Life. See latest PCN for details.

Migrate to the MityDSP-L138F-A7 drop-in replacement.



The MityDSP-L138F System on Module (SOM) is the highest performance module in the OMAP-L138 family of MityDSPs. An overview of the module family is available here. The MityDSP-L138F ARM9 system supports QNX, embedded Linux, Windows CE 6 and ThreadX operating systems. It features the dual-core OMAP-L138 CPU from Texas Instruments which provides both an ARM9 applications processor and a C674x Fixed / Floating Point DSP.

When combined on the MityDSP with the optional on-board Xilinx Spartan-6 FPGA, system designers have available two 456MHz CPUs along with the capability to add fixed function co-processing or I/O co-processing in the FPGA. The MityDSP-L138F also conveniently offers applications such as industrial embedded instrumentation.
