1 Introduction
The 8-bit AT89C5 1 CHMOS process microcontroller is designed to handle high-speed calculation and fast input/output. The typical application of MCS-5 1 single chip microcomputer is high-speed event control system. Commercial applications include modems, motor control systems, printers, copiers, air conditioning control systems, disk drives and medical equipment. The automobile industry uses MCS-5 1 single chip microcomputer in engine control system, suspension system and anti-lock braking system. AT89C5 1 is especially suitable for automobile power control, vehicle dynamic suspension, anti-lock braking and stability control, which are benefited from its processing speed and enhanced on-chip peripheral function set. Because of these decisive applications, the market needs a reliable monolithic integrated circuit widely used in industries, such as modems, motor control systems, air conditioning control systems, automobile engines and other fields. The high-speed processing speed of these monolithic integrated circuits and the enhanced auxiliary equipment set ca use them to adapt to such high-speed event applications. However, these key application fields also require these monolithic integrated circuits to be highly reliable. Robust test environment and suitable tool environment for verifying these single-chip computers ensure redundant reliability and low market risk at the component level. The engineering department of Intel platform has developed an object-oriented test environment for confirming its AT 89C5 1 automobile single chip microcomputer multilinear form. The purpose of this environment is not only to provide a robust test environment for AT89C5 1 automobile single chip microcomputer, but also to develop an integrated circuit that can be easily expanded and reused to verify several other future single chip microcomputers. Developing this environment connected 89C5 1. This paper discusses the design and principle of this test environment, its interaction with various hardware and software environments, and how to use AT89C5 1. 1 Introduction 8 AT89C5 1 CHMOS process microcontroller is designed to handle high-speed calculation and fast input/output. MCS-5 1 MCU module is applied to high-speed event control system. Commercial applications include modems, motor control systems, printers, gravure presses, air conditioning control systems, disk drives and medical equipment. The automobile industry uses MCS-5 1 single chip microcomputer, suspension system and locking brake system in the engine control system. AT89C5 1 benefits from its processing speed and the collection of on-chip peripheral functions, such as the application of vehicle power control, vehicle dynamic suspension, locking and stability control. Because of these decisive applications, the market needs a reliable cost-effectiveness controller with low disturbance ambush response, which can serve a lot of time and integrate peripheral devices required in event-driven real-time applications, and outperform the average processing power in a single routine. Equipment with unpredictable operation has high economic and legal risks. Once it enters the market, especially the decisive application such as autopilot or locking brake system, it will be wrong in the financial resource contract. Redesign the cost-effective controller, which may cost as much as $500,000. It serves a lot of time and event-driven integrated peripherals needed in real-time applications, and has a CPU with higher average processing power in a single package. The economic and legal risks of owning unpredictable equipment are high. Once entering the market, especially in mission-critical applications such as autopilot or anti-lock braking system, mistakes will be financially prohibited. The cost of redesign may be as high as 500 thousand pounds.
