Overview
The OMAP-L138EZCEA3E is a low-power applications processor from Texas Instruments, integrating a dual-core architecture that combines an ARM926EJ-S core and a C674x DSP core. This processor is part of the TMS320C6000™ platform and is designed to provide significantly lower power consumption compared to other members of this platform. It enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly develop devices with robust operating systems, rich user interfaces, and high processor performance. The mixed processor solution leverages the benefits of both DSP and reduced instruction set computer (RISC) technologies, making it ideal for a wide range of applications requiring high performance and low power consumption.
