Overview

The OMAP-L138 is a low-power applications processor based on a dual-core architecture that integrates an ARM926EJ-S RISC MPU and a C674x Fixed/Floating-Point DSP. This combination allows for efficient high-level OS management on the ARM core while offloading complex signal processing tasks to the dedicated DSP core.

Why Choose This Part

The heterogeneous architecture provides the flexibility of a Linux-capable ARM core coupled with a high-performance DSP for intensive math operations. It features a rich set of integrated peripherals including Ethernet MAC, USB 2.0 OTG, and SATA, reducing overall system bill-of-materials and board complexity.

Applications

Industrial Control
Ideal for programmable logic controllers (PLCs) and industrial automation requiring real-time deterministic processing alongside a Linux-based user interface.
Power Protection Systems
Used in smart grid infrastructure and digital protection relays where high-speed mathematical computations are needed for power quality analysis.
Professional Audio
Suitable for digital mixers and effects processors that require floating-point precision for high-fidelity audio algorithms.

Getting Started

Development is typically supported by the TI Processor SDK, which includes Linux for the ARM core and RTOS/SYSBIOS for the DSP. Engineers should evaluate the TMDXLCDK138 development kit and use Code Composer Studio (CCS) with a compatible JTAG emulator for debugging both cores simultaneously.
