Electronic components information sheets info aggregation platform with easybom.com? OFDMA changed that. By composing subcarriers into resource units (RU), OFDMA channels can dynamically divide the instantaneous bandwidth to different users. OFDMA has suddenly increased the number of users that are instantly supported. The 20MHz bandwidth in the following figure is an example. Through subcarrier allocation, 20MHz can support up to 9 devices to access at the same time, 40MHz can support 18 devices, and so on. Fig. 2 uses the number of resource units available under OFDMA’s 20MHz% 0AWi-Fi 6 in which each subcarrier is 78.125khz. 20MHz is 256 subcarriers. 6 Edge indicates that there are 6 subcarriers as protection bands from the edge. ) It can be said that OFDMA has brought about a qualitative change in the capacity of Wi-Fi channels.

With the increasing degree of automation of cars and electric vehicles, the number of semiconductors required will increase sharply. Most semiconductors are traditional analog and power semiconductors. These traditional analog and power semiconductors are produced by 8-inch factories. Because it is difficult to ensure 8-inch manufacturing equipment, it is difficult to add new 8-inch semiconductor factories. In short, self-driving cars certainly need state-of-the-art semiconductors to run advanced artificial intelligence (AI), but the need for a large number of traditional analog and power semiconductors has become the Achilles’ heel of automobile production, and it is not easy to solve this problem. Although the automobile industry has ushered in an once-in-a-century period of great change in CASE (Connected, Autonomous/Automated, Shared, Electric), it is also an era suffering from the shortage of semiconductors.

In the early CPUs, the chip integration level was very low. The CPU was a single chip. It only integrated an arithmetic unit and a controller. It could only calculate and control. At this time, the internal capacity of the CPU was useless. Memory, the CPU left The memory cannot be calculated. Back then, there was no memory in the CPU because the memory could not be integrated, and others such as the serial port could not be integrated, so there was only a single CPU. If you need to use the serial port, you need to use a serial port controller chip outside the CPU. The PCB traces are connected to the CPU, and then the entire PCB board is composed of the CPU, and these peripheral chips is called a system board. This system board can communicate with another system board. The CPU communicates with another system through its serial port controller. The serial port controller on the board communicates, and functions such as the serial port controller cannot be integrated into the CPU chip. For example, if the LCD is also used here, it is necessary to add an LCD controller chip to the periphery and connect it to the CPU through wiring. A whole board composed of these chips is called a system board. These UART controllers and LCD controllers are called peripherals. Combining them with the CPU on one board is the function implemented by a current K60 chip, but they are integrated into a small chip. The peripherals here refer to the inside of the system board, the peripherals outside the CPU are called peripherals, the CPU is called the internals, and there are only arithmetic units and controllers inside, which are called internals.
