ARM9 with Floating Point DSP SoM
The MityDSP-L138 System-on-Module (SoM) features an OMAPL138, a rich peripheral SoC, integrated into a convenient MityDSP SoM.
An overview of the module family is available here. The MityDSP-L138 ARM9 system supports QNX, and embedded Linux 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. With this module system designers have available two 456 MHz CPUs.
