艾默生/摩托罗拉MVME172P2系列VME嵌入式控制器具有2个IP插槽，允许VME嵌入式控制器用户在保持MC68060目标代码兼容性的同时实现RISC架构的性价比。通过将MC68060的标量性能与广泛的可选功能和IndustryPack接口相结合，oem可以为其应用选择准确的产品，而不是为不需要的功能付费。新的“Petra”专用集成电路(ASIC)取代了以前在IP2芯片、MC2芯片和MCECC芯片中实现的功能，提高了内存子系统的性能。内存配置开关使用户能够为需要更小内存配置的应用程序定制内存大小。

The controller is the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in accordance with the predetermined sequence. The controller is composed of program status register PSR, system status register SSR, program counter PC, instruction register, etc. As a "decision-making mechanism", its main task is to issue commands, and plays the role of coordination and command in the operation of the whole computer system. The classification of control mainly includes two kinds, namely, combinatorial logic controller and microprogram controller. Both parts have their own advantages and disadvantages. The structure of combinatorial logic controller is relatively complex, but it has the advantage of fast speed. Microprogram controller is designed with simple structure, but in modifying one machine instruction function, it needs to reprogram the whole microprogram.
