Introduction When it comes to driver development, we must mention the bus; the bus is the bridge for data transmission between devices. Computers categorize buses into three types: data bus, address bus, and control bus, which are collectively referred to as the system bus. Generally, the system bus, internal bus, and external bus are known … Read more
1. Overview The I2C bus is a very popular and powerful bus, commonly used for communication between one (or multiple) master devices and one or more slave devices. Figure 1 shows that various peripherals can share this bus, which only requires two wires to connect to the processor. This is one of the biggest advantages … Read more
This morning, we held a brainstorming session with graduate students to discuss the general concepts of SoC design. I found that many students did not grasp the core of SoC design. Now, while the discussion is still fresh, I will record it here. First of all, what is SoC design centered around? SoC design is … 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
