DSP performance in microcontroller

The C2000 real-time control MCU uses a central 32-bit CPU core, called C28x, coupled with a highly-optimized peripheral and interrupt management bus. As a cross between a general microcontroller and a digital signal processor, the C28x core brings the code density and execution speed of a DSP with the ease of use and accessibility of a microcontroller.

Enhancing the performance and capability of C2000 devices

There are four available integrated on-chip hardware accelerators that dramatically increase the performance of the C2000 MCU; Control Law Accelerator (CLA), Floating Point Unit (FPU), Trigonometric Math Unit (TMU), and the Viterbi, Complex Math, and CRC Unit (VCU).

When combining a high performance CPU core with these advanced hardware accelerators, the fast and efficient processing power required for complex real-time control systems can be realized. You can find information on each of the accelerators below as well as documentation included in C2000Ware. 

The C28x plus floating-point (C28x+FPU) processor extends the capabilities of the C28x fixed-point CPU by adding registers and instructions to support IEEE single-precision floating point operations. No changes have been made to the C28x base set of instructions, pipeline, or memory bus architecture. Therefore, programs written for the C28x CPU are completely compatible with the C28x+FPU and all of the features of the C28x documented in TMS320C28x DSP CPU and Instruction Set Reference Guide apply to the C28x+FPU.Additional instruction provided to support floating point operations are listed in the TMS320C28x Extended Instruction Sets Technical Reference Manual.

The C28x with VCU (C28x+VCU) processor extends the capabilities of the C28x by adding registers and instructions to support Viterbi decoding, Cyclic redundancy check (CRC) and Complex math.  The VCU extends the capabilities of the C28x CPU and C28x+FPU processors by adding additional instructions. No changes have been made to existing instructions, pipeline, or memory bus architecture. Therefore, programs written for the C28x are completely compatible with the C28x+VCU. Additional instructions provided by VCU are listed in the TMS320C28x Extended Instruction Sets Technical Reference Manual.

The Trigonometric Math Unit (TMU) is a fully programmable block that enhances the instruction set of the C28-FPU to more efficiently execute common trigonometric and arithmetic operations.  The instructions such as floating point division, sine computation, cosine computation, square root computation are some of the additional support provided by TMU. Additional instructions provided by TMU are listed in the TMS320C28x Extended Instruction Sets Technical Reference Manual.

A new approach to system modularity, safety, and performance.

The CLA is a C-programmable, independent, 32-bit floating-point math accelerator based on the C28x core. It has independent access to control peripherals, which enables execution of completely parallel control loops, independent of the main C28x core. The CLA gives you the benefits of parallel processing without the cost and complexity of an additional processor.

System benefits of integrated analog in a microcontroller.

Integrated analog greatly benefits many applications requiring power efficiency and the need for tightly coupled high-performance analog peripherals within a single MCU. This helps play a significant differentiating role in simplifying the analog front end design. By selecting a C2000 MCU with integrated analog, many system level costs are reduced along with the bill of materials and the board footprint. The C2000 MCU family offers a variety of analog peripherals, such as ADC, DAC, sigma-delta filters, over-voltage and PWM protection, with the purpose of increasing performance while reducing system costs.

The information below highlights the key features of each analog integrated peripheral and recommended device to begin evaluation.

The analog integration and performance you need to reduce cost and decrease board area.

Blazing fast ADCs give you accurate feedback in the time windows you need it. High speed comparators allow you to accurately test your feedback signals and quickly shutdown or alter system behavior. Integrated opamps reduce external component cost. Internal oscillators, watchdogs, VREGs, and power on reset/brown-out reset protection give you the system support you need without the extra cost and hassle of implementation.

Optimized for processing, sensing and actuation to improve closed loop performance for functional safety compliant systems

C2000 SafeTI MCUs are designed using a rigorous hardware development process and are equipped with built-in safety mechanisms to help detect and prevent or at a minimum detect and reduce the impact of dangerous failures resulting from systematic faults or random hardware faults.

Intellectual property housed in a product’s firmware can provide key competitive advantages for a business in the marketplace and is at a high risk of theft. It is straightfor­ward enough to do a visual component teardown of a system for purposes of copying an end product, but protec­tion of the firmware running on the MCU prevents full duplication of the working system. Another scenario that is increasingly common is co-development of the firmware. Many times certain system firmware is outside the main engineer­ing team, perhaps even outside the company. In these situations, one party sometimes wants to keep their firmware private, while still allowing the second to develop and test a portion of the program on the same system.

From serial interfaces like I2C, SPI, UART and even McBSP to protocols such as CAN and LIN to standards such as USB and FSI, C2000 Real-time Control MCUs come with a variety of connectivity options to keep applications in sync.
