Overview
The OMAP-L138 C6000 DSP+ARM processor, specifically the OMAPL138EZCE3 model from Texas Instruments, is a low-power applications processor. It integrates an ARM926EJ-S core and a C674x DSP core, providing a dual-core architecture that leverages the benefits of both DSP and reduced instruction set computer (RISC) technologies. This processor is designed to offer high performance while consuming significantly lower power compared to other members of the TMS320C6000™ platform of DSPs. It is ideal for original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to develop devices with robust operating systems, rich user interfaces, and high processor performance.
