The Design of the Calculator System Based on ARM7TDMI Kernel

Article Preview

Abstract:

A calculator design was created using S3C44B0X chip with ARM7TDMI as the kernel with a keypad connected to a ZLG7289A intelligent control chip through SIO synchronous serial ports as well as a LED port. The system design used hybrid programming with C language and ARM assembly language to accomplish basic calculations with LED digital display. The structured frame design makes it convenient to expand the functions of S3C44B0X, and has broad practical importance for developing uses for the built-in system both in software and hardware.
