C-51的BANK模式及代码和数据的混合BANK技术

The BANK Mode of C-51 and the Technique of Code Sharing BANK with Data

C-51的BANK编译模式是用来解决程序代码超出51系列单片机最大寻指空间的一种编译模式。它通过硬件设计与软件码中插入切换BANK页面操作相结合，实现页面存储器中不同页中代码的相互调用。本文首先阐述了C－51编译器BANK模式的使用方法。然后介绍了在C－51的BANK模式下代码和数据混合使用BANK的一种技巧。

BANK mode is a special compiler mode of C- 51. In BANK mode,the program code may exceed the maxima access-space(64k) of Intel 8051 CPU. To achieve the calling between the functions in different memory bank page, BANK mode combines the special hardware design with the addition codes in software. In this thesis,after expounding the way to use the BANK mode of C51, a techique of CODE sharing BANK with DATA was raised.
