基于ARM Cortex-M0+KL系列MCU的构件化汇编框架研究

ARM Cortex-M0+是2012年新发布的一款将逐步8位/16位微处理器市场的32位低功耗、高性能处理器,规范的汇编框架与样例是一个新微处理器深层次应用开发的基础。鉴于目前ARM Cortex-M0+的汇编程序资料与样例程序十分匮乏,加之汇编设计的复杂性,在充分分析ARM Cortex-M0+汇编寻址方式与指令系统的基础上,以Freescale半导体公司于2013年正式发布的ARM Cortex-M0+KL系列MCU为蓝本,基于CW10.3开发环境,结合软件构件设计思想,提出构件化ARM Cortex-M0+汇编框架,并编制GPIO汇编构件,给出应用实例。旨在降低读者学习ARM Cortex-M0+汇编程序的难度,完成第一个ARM Cortex-M0+规范化汇编程序。

遗传算法在汇编语言程序分片中的应用

程序分片在程序设计、并行、诊断与测试等方面均有广泛的应用，介绍了一种用遗传算法计算最小动态分片的算法。将整个程序看成是一个染色体，而每条语句看成为基因，通过现有遗传算法的操作：选择、变异、交叉等，就可以计算出动态分片，并给出了一个诊断汇编语言的实例。     

An improvement for the McGill University Random Number Package

This paper documents and provides code for two new entry points which increase the flexibility of the McGill University Random Number Package. With these additions the user can access internal locations containing the pseudo-random integers that control the random sequences produced by the generator. A detailed example of the use of the new entry points is provided. Finally, some comments about the documentation of random number generators are made.

A mechanically verified language implementation

This paper briefly describes a programming language, its implementation on a microprocessor via a compiler and link-assembler, and the mechanically checked proof of the correctness of the implementation. The programming language, called Piton, is a high-level assembly language designed for verified applications and as the target language for high-level language compilers. It provides executeonly programs, recursive subroutine call and return, stack based parameter passing, local variables, global variables and arrays, a user-visible stack for intermediate results, and seven abstract data types including integers, data addresses, program addresses and subroutine names. Piton is formally specified by an interpreter written for it in the computational logic of Boyer and Moore. Piton has been implemented on the FM8502, a general purpose microprocessor whose gate-level design has been mechanically proved to implement its machine code interpreter. The FM8502 implementation of Piton is via a function in the Boyer-Moore logic which maps a Piton initial state into an FM8502 binary core image. The compiler and link-assembler are both defined as functions in the logic. The implementation requires approximately 36K bytes and 1400 lines of prettyprinted source code in the Pure Lisp-like syntax of the logic. The implementation has been mechanically proved correct. In particular, if a Piton state can be run to completion without error, then the final values of all the global data structures can be ascertained from an inspection of an FM8502 core image obtained by running the core image produced by the compiler and link-assembler. Thus, verified Piton programs running on FM8502 can be thought of as having been verified down to the gate level.This work was supported in part by the Defense Advanced Research Projects Agency under DARPA Orders 6082 and 9151, contract MDA904-87-C-H009.
