Overview
The OMAP-L138 C6000 DSP+ARM processor, produced by Texas Instruments, is a low-power applications processor that integrates an ARM926EJ-S RISC MPU and a C674x fixed and floating-point VLIW DSP core. This dual-core architecture combines the benefits of both DSP and 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 processor operates at a clock speed of up to 456 MHz and is designed to provide significantly lower power consumption compared to other members of the TMS320C6000™ platform of DSPs.
