Working Principle

TMS320F2812GHHS is a 32-bit RISC-based microcontroller based on the ARM926EJ-S RISC processor core. The TMS320F2812GHHS includes an ARM926EJ-S processor core and 32K bytes of on-chip SRAM for instruction, data and system functional requirements. The ARM926EJ-S processor core is developed to provide high performance and low power consumption, and it is highly compatible with other ARM processor-based IP cores. The TMS320F2812GHHS can execute program instructions from ROM, RAM or EEPROM memories, depending on the application’s requirements.

The TMS320F2812GHHS has two primary application interfaces: peripheral bus, memory interface and digital I/O. The peripheral bus interface provides access to the processor\'s high-speed peripherals and external memory devices, while the memory interface contains the interface to the external memory management unit. The digital I/O can be used to connect digital peripheral devices. The processor core can access and control digital I/O devices via the serial communication interface.

TMS320F2812GHHS supports three kinds of bus types: RMII, SMI and IR. The RMII bus is used for external peripheral and memory devices that require high-speed access. The SMI bus is used for on-chip peripherals and memory devices, while the IR bus is used for low-speed external devices, such as keyboards and mice. The core also contains an embedded Ethernet MAC which provides data access over the bus.

The processor core contains several control systems, including the DMA controller, interrupt controller, power management unit and a watchdog timer. The DMA controller is used for transferring data between the on-chip peripherals and external memory devices, while the interrupt controller enables the processor to respond to external and on-chip interrupts. The power management unit monitors the on-chip power consumption. The watchdog timer is used to reset the processor in the event of an error.
