Abstract


The electronic calculator is a typical large scale digital integrated circuits, mainly by the combination of the microprocessor and peripheral display circuitry , the keyboard interface circuit . General calculator has four operations, square root operation function scientific calculator with trigonometric, exponential and logarithmic functions such as arithmetic functions . The calculator layout of a company in Hong Kong , the subject , the overall circuit extracted Calculator , respectively, simulation and digital simulation . Function of the overall circuit module division and analysis , to understand the the calculator chip hardware circuit design method . Calculator key commands , the understanding of the software implementation process , and summarizes the entire command system command table . Firstly, on the basis of division by the function module in the completion of the calculator , on the power supply module , a clock module , an arithmetic logic unit ALU module control register ROM module , the ROM address generation circuit structure and operation of the module, the address decoder module , a register array module . the principle is analyzed , mastered their design methods . The keyboard scanning and display output port complex implementation process , principles and circuit analysis and keyboard scanning and display output . The article also explains the need to build digital simulation platform build process . This issue through the analysis of the instruction code , mastered the four arithmetic algorithm BCD code calculator , explore and square root calculation algorithm . Through the study of the subject , the design of the the calculator hardware circuit design and software programming has in-depth understanding of the sound design function calculator technology accumulation .
