In previous articles, we have completed discussions related to module testing. Starting from this section, we will introduce tests related to PACK, beginning with some knowledge about communication to lay the groundwork for subsequent chapters. In communication, we often encounter the term bus, such as address bus, data bus, control bus, etc. The English term … Read more
Source: Electric Control Knowledge Transporter 5. MOST Bus MOST is a data bus technology specifically developed for in-vehicle use, serving multimedia applications. MOST stands for “Media Oriented Systems Transport”. Since BMW’s 7 Series first adopted MOST (Media Oriented Systems Transport) technology, the popularity of this technology has increased rapidly in recent years, enabling real-time transmission … Read more
Microcontroller Instruction Execution Let’s consider a question: when we write an instruction into the microcontroller using a programmer, and then take the microcontroller out, it can execute that instruction. So this instruction must be stored somewhere in the microcontroller, and this place can retain the instruction even after the microcontroller loses power. What is this … Read more
1. Overview of Buses The computer system is centered around the microprocessor, and all devices must connect to the microprocessor and work in coordination. Therefore, the concept of a bus is introduced in the microprocessor, where all devices share the bus, and at any given time, only one device can send data (multiple devices can … Read more
1. Machine Language Machine language is a collection of machine instructions, which are commands that a machine can correctly execute. The machine instructions of an electronic computer are a series of binary data, which the computer converts into a series of high and low voltages to drive its electronic components for computation. 2. Assembly Language … Read more
Bus applications are very widespread in the field of computers. (1) The method of transmitting information via the system bus can be divided into the following three types: 1. Data Bus 2. Address Bus 3. Control Bus (2) According to the usage range of the bus, it can be further divided into many types: such … Read more
