Currently a small three phase motor challenge for many embedded system is running in a very short period of time to perform a series of important tasks at the same time. Direct memory access (DMA) module provides the solution is to make through hardware control data using interrupt source to automatically read single phase motor price or write. However, this scheme before the arrival of waiting for next interruption usually DMA to execute commands to read or write, only its function will be restricted. stator In embedded systems, the interrupt events often involved in other logical processing. Before moving the data to the final destination, for example, to intervene to confirm or to modify the Electric motor data signal processing. Thus, a backed by DMA interrupt often can only make part of generator price the work, the CPU will be set aside part of the main program to complete these tasks by interrupt. In this way, the interrupt processing makes the CPU performance in other functions of the diminished. In addition, must have the accurate time single phase 3 hp motor requirements to ensure the normal operation of the system at the same time to deal with complex applications.

XGATE application is in order to improve the electric motor parts response speed and reduce the CPU interrupt of the load, through the interrupt execution at the same time with the CPU in order to achieve the purpose of the operation. Then the XGATE can be used to do? motor rotor XGATE is positioned in the fast interrupt processing, can reduce the load on the CPU interrupt processing. Most embedded applications require many interrupt program to deal with simple function, the processor often perform tasks with high rate. These are usually associated with interface functions, such as the speed controller to control feedback and communicate with other parts of the system. XGATE is used to help CPU of these events. XGATE of an important characteristic is its setting although very simple, but allow develop complex applications. XGATE DMA controller is better than that of a smart, because it provides the ability of a complex I/O processing. When the XGATE use with CPU12X nuclear, there are some limitations to consider, but will not affect XGATE the designed function. XGATE provides applications with a higher level of interruption, through Shared some service programs and processes to shorten the work of CPU time.
