Abstract


Calculator is a typical large-scale digital integrated circuits , it is a complete digital system , a large number of digital circuit module is integrated in its internal arithmetic logic unit ALU control system module , display driver module , it will all its function modules focused on a chip , constituting a microprocessor system reflects the basic idea of the microprocessor design . Firstly, the idea of basic building calculator circuit fairly detailed , and introduced the idea of the circuit control system , according to the the thought control circuit to complete the design and implementation of the circuit control system and the traditional control module to improve and optimize its control functions to be extended . Circuit control micro program control minds to attain the control MPU structured design , the use of ROM storage instructions , and then call the system work , the hardware design software , saving a lot of devices than traditional combinational logic control . In addition, a more in-depth analysis on the calculator display and driver circuit , display output port multiplexing and display output principle expounded works for keyboard scanning and LCD driver circuit and circuit the display driver module functional simulation , the simulation shows that the circuit reuse ideas to be fully realized . In accordance with the requirements of the circuit serial design thinking , the circuit ALU serial design and serial computing ideas through an adder and a serial shift register and verify the design , through simulation of the full reduction function correctness. Finally , on the circuit of the system module and instruction system corresponding to the simulation , and the important module further verify the correctness of the system module functions .
