Overview
The OMAP-L138 C6000 DSP+ARM processor, produced by Texas Instruments, is a low-power applications processor that integrates an ARM926EJ-S core and a C674x DSP core. This dual-core architecture combines the benefits of both DSP and reduced instruction set computer (RISC) technologies, enabling original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to develop devices with robust operating systems, rich user interfaces, and high processor performance. The OMAP-L138 is designed to provide significantly lower power consumption compared to other members of the TMS320C6000™ platform of DSPs, making it suitable for a wide range of applications requiring high performance and low power.
