| Abstract: | In this paper, the principle and the components of an intelligent data-acquisition chip are introduced, and the techniques of allotting memory of the ISA bus and the microprocessor are discussed in detail. Due to the arbitration problems while the ISA bus and the microprocessor access the dual-port RAM at the same time, the hardware arbitration and software arbitration are presented, and the flow chart of the data communication and data sharing with the chip is given. |
