The C2000 devices from Texas Instruments incorporate different features such as a floating-point unit (FPU), Trigonometric math Unit (TMU) and Viterbi, Complex Math, CRC Unit (VCU) and Control Law Accelerator (CLA). These features impose their own requirements in terms of a specific Code Composer Studio (CCS) and Codegen tools versions. 

This application report from Texas Instruments is intended to provide a deeper look into the components that differentiate the C2000 Microcontroller Unit (MCU) as it pertains to Real-Time Control Systems. The focus is on features that Texas Instruments (TI) believes have measurable impact to overall system performance as well as increased bandwidth to the MCU. 

Pulse Width Modulation (PWM) is a powerful way of encoding analog signal levels and is commonly used for controlling DC power to an electrical device. PWM can also be used for data transmission by varying the output pulse width proportionally with the data to be transferred, but a powerful decoding unit is required at the receiver. 

Modern AC servo drives, depending on the end application, need high-bandwidth current control and speed control to enable superior performance, such as in CNC machines or in fast and precision control applications. Because of the highly time critical computational burden of these systems and the need for flexible PWMs, a combination of FPGAs, fast external ADCs, and multiple MCUs are used by many designers. 

Just like a CPLD or FPGA, CLB is composed of programmable logic primitives that can be configured in many ways to implement custom blocks of logic. Instead of using VHDL or Verilog to configure these logic primitives, CLB is programmed with a GUI-based SysConfig tool and function calls. Since the configuration method is different, the CLB is technically not a CPLD or FPGA, but it can be used to achieve identical results.

Does your industrial control system include customised logic? Do you have an FPGA, CPLD, or external logic components supplementing your embedded controller and wonder ‘why can’t this all be done in one device?’ Are you using this additional logic because your MCU peripherals don’t give you all the capability you need?

The AWR1443 from Texas Instruments millimetre wave (mmWave) sensor is a highly integrated 76–81-GHz radar device that serves as a single-chip radar solution suitable for proximity-sensing automotive radar applications. 

The use of millimetre wave (mmWave) technology in advanced driver assistance systems (ADAS) has grown tremendously in recent years. Applications have rapidly evolved, from comfort functions such as adaptive cruise control (ACC), to safety functions such as emergency braking, to newer applications such as pedestrian detection and 360° sensing. 

The use of radar technology has grown tremendously in recent years. In the automotive context, the primary radar applications can be broadly grouped into corner radars and front radars. Corner radars (rear and front) are typically short-range radar sensors that handle the requirements of blind-spot detection (BSD).
