The OMAP-L138 EZDSP Cortex A8 microcontroller is an advanced embedded processor designed to offer performance, high system integration and flexibility. This processor was developed by Texas Instruments (TI) in collaboration with Convergent Semiconductor Illumination, LLC. It is the first processor in the OMAP family to use a low-power, high-performance ARM Cortex A8 core.

The OMAP-L138 EZDSP Cortex A8 microcontroller is a single-chip system-on-chip (SoC) solution with an integrated ARM Cortex-A8 processor core. It includes high-speed bus architecture, dedicated DMA ports, and multiple peripheral blocks. It is based on TIs OMAP-L138 System Architecture, a highly optimized set of hardware and software components that provide scalability and flexibility for making high performance embedded devices. The device is ideal for signal processing applications such as medical imaging, audio/voice recognition, video signal recording and playback, machine vision, avionics, telecommunication, industrial automation, automotive and consumer entertainment.

The OMAP-L138 EZDSP Cortex A8 microcontroller features an embedded 32-bit ARM Cortex A8 processor core with two ARM Thumb-2 instruction set architectures (ISA) and advanced on-chip SIMD co-processor support. An integrated 32-bit DDR2 memory controller, an embedded Performance Monitor Unit (PMU) and Power Management Unit (PMU) are features of the OMAP-L138 SoC. It also provides a comprehensive analog-to-digital converter (ADC) block, a 12-bit parallel data port (PDP) and a 10/100 Mbps Ethernet MAC with DMA support.

The key application areas for the OMAP-L138 EZDSP Cortex A8 microcontroller are medical, industrial, image processing, machine vision and avionics. It is used in medical applications such as medical imaging and EEG analysis. In the industrial field it is used for motion control, industrial automation and SCADA systems. The device is also suitable for image processing applications and provides high performance, low power and low cost digital signal processing for industrial, security, automotive and consumer video applications. In machine vision applications, the device is used for real-time processing of video images. In avionics, it is used in flight control computers, onboard communications systems and airborne navigation systems.

The integrated ARM Cortex A8 processor core provides a highly efficient and flexible platform to drive the processing power needed for these applications. The processor core implements the ARMv7-A architecture and supports the ARM Thumb-2 ISA including ThumbEE instruction set extensions. The core offers both symmetric and asymmetric configurations. The symmetric configuration allows one instruction to be simultaneously executed on all the four processor cores. The asymmetric configuration provides four independent processor cores, each with its own local memory, instruction queues and instruction prefetchers.

The OMAP-L138 EZDSP Cortex A8 microcontroller is also equipped with a highly integrated programmable DMA controller that is optimized for throughput and deterministic latency. It provides an Efficient DMA port that prevents data stalls during data transfers. The DMA controller supports symmetric, asynchronous and burst operations for data transfers. The device\'s high performance and low power operation makes it suitable for use in medical, industrial, motion control, security, automotive and consumer video markets.

The OMAP-L138 EZDSP Cortex A8 microcontroller features high-speed I/O channels, communication peripherals, and advanced interrupt control. The on-chip peripheral blocks include two Serial Serial Interface (SSI) modules, two multi-channel SSI ports, two USB 2.0 slave transceivers, two Ethernet MACs, one Fast Ethernet port, two external bus controller (EBC) ports, an on-chip interrupt controller, and a system reset controller.

The device also includes an on-chip power management unit (PMU) that enables the system to optimize system power consumption. The PMU can monitor the power supply of each of the system\'s power domains and manage power states to minimize power consumption. The PMU also allows the system to enter a lower operational power state when it is not used. This feature helps the system to minimize wake-up time, thereby reducing system power consumption.

In conclusion, the OMAP-L138 EZDSP Cortex A8 microcontroller is a high-performance, low-power, low-cost processor designed for embedded applications. It is ideal for signal processing applications such as medical imaging, audio/voice recognition, video signal recording and playback, machine vision, avionics, telecommunication, industrial automation, automotive and consumer entertainment. The device includes an integrated Cortex A8 processor core, DMA controller, an Efficient DMA port, peripheral blocks and powerful power management functions for optimized system power consumption.
