Embodiment Construction
[0027] This system needs to cooperate with the central processor of the specific on-board computer to work together, and its interface needs to lead out the data bus line, address bus, and control bus of the processor. In order to have versatility, this system needs to lead out 16 data buses, 25 address buses, and 3 control buses of the external processor, in which the control lines are connected to the read and write status indication, read enable and write enable of the field programmable device, The mode selection control line is given as the high address line.
[0028]Inside the system, among the connections drawn from the external processor, the low address lines A0 to A17 are connected to the static memory in the system, and all other connections are connected to the field programmable devices in the system. The 16-bit data line Dinout (0~15) is expanded into Dinouta (0~15), Dinoutb (0~15), Dinoutc (0~15) 48 bits through the field programmable device, connected to the st...
