mcs-51单片机实用子程序库1（MCS-51 SCM utility subroutine library 1）

mcs-51单片机实用子程序库1（MCS-51 SCM utility subroutine library 1） MCS-51 microcontroller practical subroutine library (a) content There are a number of versions of the subroutine library published, they have their own characteristics. The library opened in the square approximation algorithm for rapid algorithm, it can achieve the accuracy of Newton iteration of the same, and about twenty times faster, more than double the speed of fixed-point division. The book library made a major revision of MCU application design technology an appendix to the subroutine library: (1) according to the popular IBM PC assembly language development system for the provisions of the host, the reader does not have to be modified, can be used directly. (2) further testing and optimization of floating-point subroutine library for conversion subroutine of the decimal floating-point and binary floating-point numbers were completely rewritten, improves the precision and reliability. (3) has added a number of floating-point subroutine (transfer, zero, zero, etc.) the preparation of the data processing program becomes more simple and intuitive. In the instructions in the list of the main items: label, entrance conditions, export information, effect of resource and demand of each item stack, please refer to the meaning of MCU application design technology the sixth chapter 6.3.7 section. The list of procedures listed the four columns: labels, instructions, operands, notes. For the convenience of the reader to understand, detailed notes. Use the following method subroutine library: 1. subroutine library will link all the contents in the application process, the compiler can be unified. Has the advantages of simple and convenient, drawback is that the procedure is too long, a large number of unrelated subroutines are also included. 2. only the relevant part of the content link in the subroutine library in the application process, the compiler can be unified. Some subroutines need some low-level subroutine
