The real-time control

subsystem is based on TI’s 32-bit C28x DSP core, which provides 120 MHz

of signal-processing performance for floating- or fixed-point code running from

either on-chip flash or SRAM. The C28x CPU is further boosted by the Floating-Point Unit (FPU), Trigonometric Math Unit

(TMU), and VCRC (Cyclical Redundancy Check) extended instruction

sets, speeding up common algorithms key to real-time control systems.

The CLA allows significant offloading

of common tasks from the main C28x CPU. The CLA is an independent 32-bit

floating-point math accelerator that executes in parallel with the CPU.

Additionally, the CLA has its own dedicated memory resources and it can directly

access the key peripherals that are required in a typical control system. Support of

a subset of ANSI C is standard, as are key features like hardware breakpoints and

hardware task-switching.

The F28003x supports up to 384KB

(192KW) of flash memory divided into three 128KB (64KW) banks, which enable

programming and execution in parallel. Up to 69KB (34.5KW) of on-chip SRAM is also

available to supplement the flash memory.

The Live Firmware Update hardware

enhancements on F28003x allow fast context switching from the old firmware to the

new firmware to minimize application downtime when updating the device firmware.

High-performance analog blocks are

integrated on the F28003x real-time microcontroller (MCU) and are closely coupled

with the processing and PWM units to provide optimal real-time signal chain

performance. Sixteen PWM channels, all supporting frequency-independent resolution

modes, enable control of various power stages from a 3-phase inverter to power

factor correction and advanced multilevel power topologies.

The inclusion of the Configurable

Logic Block (CLB) allows the user to add custom logic and

potentially integrate FPGA-like functions into the C2000 real-time

MCU.

Interfacing is supported through

various industry-standard communication ports (such as SPI, SCI, I2C, PMBus, LIN,

CAN and CAN FD) and offers multiple pin-muxing options for optimal

signal placement. The Fast Serial Interface (FSI) enables up to 200Mbps of

robust communications across an isolation boundary.

New to the C2000 platform is the Host

Interface Controller (HIC), a high-throughput interface that allows an

external host to access the resources of the TMS320F28003x directly.
