Overview
The MityDSP-L138 System on Module (SoM) features a Texas Instruments OMAP-L138, a rich peripheral SoC, integrated into a convenient MityDSP SoM. The MityDSP-L138 ARM9 system supports embedded Linux, QNX, Windows CE6 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. With this module system designers have available two 456MHz CPUs.
