It is used in many embedded applications such as industrial control, aerospace and defense, communication, and instrumentation among others. The processor is designed to provide optimal performance in a broad range of applications while maintaining reliability and power efficiency.

The LS2044AXE7TTB processor is compliant with the ARMv9-A architecture and implements a Quad-Core Cortex-A35 processor running on 64-bit technology. It is provided with a cache-coherent system, dedicated memory expansion and an adjustable voltage. It has up to 8GB of RAM and 128GB of storage.

The LS2044AXE7TTB processor also features an extensive variety of interfaces, such as dual Gigabit Ethernet ports with network port supporting up to 1000Mbps; dual PCIe Gen3 x8 interfaces with up to 8GB/s throughput; NAND flash interface; SATA interface (for storage expansion) and other crypto/security features.

The processor is highly power-efficient and supports a wide range of hardware with integrated instruction and data caches, providing the ability to access data quickly in the most taxing applications. It offers various power saving modes that make it ideal for embedded applications.

The processor includes a CoreSight Embedded Trace Module (ETM) with a dedicated trace port, allowing for debug tracing of the processor core and system peripherals. This helps in enabling developers to perform in-depth system and application analysis and debugging.

Working principle:

The LS2044AXE7TTB processor follows the Von Neumann architecture, where the same bus is used for both instruction fetch and data access/store operations. The processor also utilizes the Harvard architecture to some level, where data and instruction memory and paths are separated, allowing simultaneous execution of multiple instructions and faster access of data.

The processor uses a Decode and Execute (DE) format to process instructions. When an instruction is fetched, the processor decodes it, assigns the required processing elements, and executes the instruction. The processing elements used might include Arithmetic Logic Unit (ALU) for processing data and executing instructions, control registers to store the control instructions, and memory which may be main memory or cache memory depending on the instruction being executed.

The processor is optimized for low power usage and supports various power-saving modes. It is equipped with various peripheral interfaces for enhanced data communication, system integration, and security.

Additionally, the LS2044AXE7TTB processor features a CoreSight Embedded Trace Module (ETM), which helps providing debug tracing of the processor core and system peripherals, allowing developers to perform in-depth system and application analysis and debugging.
