TMS320VC5402 (VC5402) doesn ' t have pro- grammable non- volatile memory, so it is necessary to expand non- volatile memory for saving program codes and parameters. In many applications, this architecture makes design complex.
This paper presents the process building the TFFS file system on VxWorks RTOS,taken INTEL 28F320J3A StrataFlash as an example. The purpose is offering a method storing program and data for embedded system.
The single-chip in the main controlled circuit is AT89C52 which produced by ATMEL company in American. The program was stored in its internal RAM. The keys' and sensors' interrupt signals and step motors' control information was processed by parallel communication.
Through using graph program and blocking program idea, the level graph interface, data acquisition and processing of oil cargo's parameters, database saving as well as data transmission in network are finished.
The article is mainly about the Powermeter Data Collecting System, which the microcomputer 89C52 is the central component and the X25045 of the Xicor company is used to store the collected data. Meanwhile the circuit diagram of interface of 89C52 and X25045 is given and the program flowchart of the data collecting and storing is given too.
The CCITT High-Level Programming Language--CHILL is the standard programming language which is used for Stored Program Control(SPC)telephone exchange. A practical subset of CHILL, which retains all important characteristics and all concurrent functions except the signals, has been chosen and implemented. This subset is named Mini-CHILL. The techniques of implementing Mini-CHILL are emphasized in this paper.)
Decompile is the tool to translate a low program language to a high program language. Program graph of decompile code access is introduced to analyse the controling flow of a code program, and give the algorithm for restoring controling structure and the translation of program graph in controling flow analysis.
