Overview

The OMAPL138EZWT3 (OMAP-L138) is a heterogeneous SoC that pairs a TI C6000-class DSP with an ARM-based host processor on a single chip. It is intended for embedded real-time signal processing combined with a general-purpose application processor for control, user interfaces, or running an OS. The architecture makes it suitable where computationally intensive DSP tasks must run alongside higher-level software.

Why Choose This Part

Choose this part when you need a proven split of real-time DSP throughput and general-purpose processing in one device. The dedicated DSP core lets you implement deterministic, optimized signal algorithms while the ARM handles Linux or RTOS-based system tasks and connectivity. TI provides development tools and example code to support partitioning workloads between the two cores.

Applications

Multichannel audio processing
Perform real-time filtering, mixing, and codec processing on the DSP while the ARM handles control and I/O.
Industrial motor control and drives
Run deterministic control algorithms and sensor signal processing on the DSP with the ARM managing communications and HMI.
Communications baseband and protocol processing
Offload compute-heavy modem and signal-processing routines to the DSP while the ARM runs protocol stacks and system management.
Embedded image/video preprocessing
Use the DSP for filtering, compression, or feature extraction and the ARM for system orchestration and networking.

Getting Started

TI supplies evaluation modules (OMAPL138 EVM / LCDK) and software packages to accelerate development. Use TI Code Composer Studio for DSP development and the TI SDKs; use a standard ARM toolchain (or CCS) for the ARM side. Development kits typically include a JTAG/debug interface and example projects demonstrating DSP/ARM partitioning and Linux on the ARM core.
