The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.

基于MATLAB/Simulink的汽車ABS半實物仿真,本文所研究的是一種基于MATLAB/Simulink的汽車防抱死剎車系統(tǒng)(ABS)的半實物仿真的方法。本方法利用Simulink提供的模型建立車輛的傳動系模型、自動變速箱模型和ABS模型等。所建成的這套半實物仿真系統(tǒng)既可在軟件環(huán)境下對汽車進行仿真,也可以通過I/O接口與ABS系統(tǒng)相連接以觀察系統(tǒng)的仿真效果,檢驗控制算法的合理性。通過合理改變相應(yīng)參數(shù),本系統(tǒng)還可以模擬實際汽車在不同工況下的工作情況,極大提高了汽車電子設(shè)備的研發(fā)工作的效率。同時,本系統(tǒng)也可用于教學(xué)演示。
