Overview
The OMAP-L132 C6000 DSP+ARM processor, produced by Texas Instruments, is a low-power applications processor that integrates an ARM926EJ-S RISC MPU and a C674x DSP core. This dual-core architecture combines the benefits of both DSP and RISC technologies, offering high-performance processing with significant power savings. The device is designed to enable original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly develop devices with robust operating systems, rich user interfaces, and high processor performance.
