Working Principle

The working principle of the LM3S800-EGZ50-C2T is based on the ARM Cortex-M3 processor core. The ARM Cortex-M3 is a low-power and high-performance 32-bit processor core. It has a flexible architecture, allowing for easy and efficient design of embedded systems. The processor utilizes the Harvard architecture, meaning it has separate instruction and data buses, allowing it to fetch instructions and data at the same time and process them independently.The Cortex-M3 core includes several features such as a Nested Vectored Interrupt Controller (NVIC), a Memory Protection Unit (MPU), and an instruction and data fetch unit. The NVIC is a flexible interrupt controller that is used to handle interrupts and exceptions generated within the processor. The MPU can be used to protect memory regions from access by unauthorized software and also provides hardware assisted context switching. The instruction and data fetch unit is responsible for fetching instructions and data from the memory, caching them, and then sending it to the processor core for execution.In addition to the ARM Cortex-M3 core, the LM3S800-EGZ50-C2T also includes several peripheral modules such as I2C and SPI communication controllers, 16-bit analog-to-digital and 12-bit digital-to-analog converters, JTAG/SWD debug interface, and many more. These peripheral modules can be used to interface with various devices and sensors, providing a comprehensive system solutions.
