What are the benefits of the Toshiba Vector Engine Coprocessor?
Today, as the functions of equipment are increasing day by day, motor control is becoming more and more complex, and the cost of hardware and the software load of the processor increase, which also brings new challenges to hardware and software design. Developers urgently need a new solution to overcome these new challenges. Therefore, in today's motor control technology, vector control of complex high-speed calculations and high-level software development are a new trend.
It provides up to 16 task combinations to choose from. By combining the customer's system with the vector engine, it is easier to achieve high-speed and high-level motor control, and higher flexibility can be achieved in motor control.
Toshiba's vector engine coprocessor is a microcontroller dedicated to motor control. The vector engine performs typical calculations in vector control, including conversion from three-phase current to two-phase current and conversion/reverse conversion of rotating coordinates. Because the position estimation and speed control are specified by the user and will change with the system configuration and control method, when the position estimation and speed control are executed by software, these functions of the vector engine can reduce the load of the CPU and at the same time. The burden of developers.
Significantly shorten the motor control processing time
Traditional motor control needs to be implemented by the CPU through software programs. The typical calculations in Toshiba's vector control are implemented by the vector engine coprocessor. Therefore, the software load of the CPU working in vector control can be reduced. This reduction can improve user system performance because CPU resources can be allocated to PFC, sensor processing, or communication systems.
Using the vector engine and the CPU together to perform two-channel calculations in parallel can significantly reduce the CPU processing time. Without a high-speed CPU clock, the calculation processing efficiency of the two motors can be improved. Some power supply, heat dissipation and EMC problems are also Then overcome.
Provide easy and flexible scheduler
In addition, the vector engine includes typical calculations for the conversion of three-phase motor current to two-phase, or the conversion/inverse conversion of rotating coordinates. The task configuration of the vector engine is a scheduler, with up to 16 combinations of tasks. These various types of schedulers provide a higher degree of flexibility for motor control, and the vector engine can support multiple types of motor work.
Because the typical calculations processed by the vector engine can reduce software programs and the number of compiled programs. This means that the impact of compiler performance or optimization options can be reduced, thereby reducing the burden on developers.
