Texas Instrument's family of ARM-based OMAP processors are increasingly popular with embedded systems designers for use in high growth markets such as embedded consumer and mobile devices, wireless sensors, automotive, industrial control and networking.

At the same time the main markets for Intel's x86 architecture – desktops, laptops and servers – have either stagnated or declined. For Intel to move into the new growth markets will be a difficult proposition since it is facing determined competition by more than three dozen electronics companies that have standardized on the ARM architecture. Through either internal development or acquisition, Intel is now trying to do everything it can to make itself a viable player in these markets: developing processes that achieve lower power operation, build up a digital signal processing capability, and establish a common framework for the development of software, among other strategies.

But such things are a case of “been there, done that” for ARM licensees such as Texas Instruments, which has worked hard to establish the ARM CPU as the processor of choice for embedded developers. A good example of how the architecture is being used is “Porting Embedded Windows CE 6.0 R2 to the OMAP-L138,” a three part series by Artisom Staliarou and Denis Mihaevich on the design of a matrix RGB LED display controller based on the L138 SoC and the Xilinx Spartan6 FPGA. Several other articles on the OMAP-L138 you should find useful are:

Managing intelligent I/O processing on DSP +GPP SoCs
Managing power in applications using dual OSes
Bare metal embedded software development with/without an RTOS

Also included here are design resources on developing applications across the entire range of TI's OMAP ARM CPUs and other related ARM derivatives. Among these, my Editor's Top Picks are:
