The structure of a single chip computer controller double

8-bit machine is likely to lose their supply, for which the system's CPU by a structural model detained for interrogation. This situation can supply assembly systems, thus extending the system's \The interface design has some similarities, the difference is part of the special export line and the control signal line. MCS5 the P1 port output with the MCS96 HSO-based high-speed system control port. And then also use the drive with a separate control panel is connected, this is mainly to strengthen the isolation,ugg botas, improve anti-jamming capability and reliability,belstaff uomo, but also to facilitate maintenance. Keypad / display is Intel8279 extension, the same as the method and the conventional method, the data line and the graph data bus, chip select signals is P27. Not shown in Figure 1, Figure 1 system to drive the hardware structure of our production of printed circuit board, there are two CPU base, the assembly can be based on the specific circumstances of supply plug CPU, the other,ugg italia, n. - Love surplus mouth __ mandarin duck _ �� \8-bit machine control system or control system 16. 3 software architecture structure of the system has two modes, it also must have two sets of software systems to be able to work properly. Despite the series of machine and MCS96 MCS51 series of machine instruction systems, the structure of the software have been identified (Figure 2), development of two \Two sets of software were fired at different ROM chip, and supporting the use of plug-in CPU. For convenience,tory burch outlet, all programs are stored in ROM, there is no ROM in the CPu stored within the zone,microsoft outlook, so that non-ROM can use the core model number CPU, no security measures introduced in this. Figure 2 System Block Diagram 4 Conclusion This article introduced the \completely different systems, and can maintain a longer period of time, we now have two configurations of the products, the operation is very reliable.
