System Peripherals
R2026bCreate Simulink® models with the system peripherals such as CLA, GPIO, software interrupt trigger, and watchdog available on TI’s C2000™ microcontrollers. Configure the Simulink model to interface with supported target hardware using model configuration parameters. You can map tasks and peripherals in a model to hardware board configurations using Hardware Mapping tool. The blocks are processor specific and is not available on all TI’s C2000 microcontrollers.

Control Law Accelerator in DC-DC Power Conversion
Manage the voltage mode control (VMC) algorithm for a closed loop DC-DC power conversion system by using the Control Law Accelerator (CLA). An auxiliary software current protection loop is managed by C2000 CPU. In the TMS320F28379D and similar processor families, the CLAs execute the hard-realtime portions of the algorithm can connect with hardware peripherals such as ADC's and PWM's. The C2000 CPU is better suited for hard real-time portions of the algorithm that require multitasking, handling of asynchronous events, and communication with other cores. While this example extends the DC-DC buck converter developed in the DC-DC Buck Converter on MCU example, the strategy presented can be applied to any design where a resource intensive hard real-time process executes on the CLA and real-time multi-tasking processes run on C2000 CPU.
