Orthogonal frequency division multiple access OFDMA: Friends who are familiar with Wi-Fi should know that the empty port of Wi-Fi adopts orthogonal frequency division multiplexing (OFDM) modulation, that is, the whole bandwidth is composed of orthogonal subcarriers. In Wi-Fi 6, the 802.11 working group introduced OFDMA access from LTE. The addition of such an “A” word can be said to have brought a qualitative change to the network capacity. As shown in the figure on the left below, Wi-Fi 5-based OFDM can only allocate all the bandwidth in the channel to one user at any one time, even if that user’s data needs do not need to take up all the bandwidth. When other users connect to the network, they need to wait for the next sending opportunity window (TXOP). This is very inefficient in the use of channel resources, especially when there is a significant increase in equipment.
Due to the spread of the global COVID-19 epidemic in 2020, automobile production is in the doldrums (figure 1). The number of cars produced worldwide, which was 92.18 million in 2019 before the COVID-19 epidemic, fell by 14.56 million to 77.62 million in 2020 and appears to have fallen by 1.2 million to 76.42 million in 2021. The decline in car production in 0A2020 was caused by the COVID-19 epidemic, which led to a sharp drop in demand. However, the downturn in car production in 2021 is mainly due to a shortage of semiconductors. In fact, by 2021, the shortage of semiconductors has made it impossible to build cars, and the governments of Japan, the United States and Germany, with automobile as the core industry, have made requests to TSMC to increase the production of on-board semiconductors through the government of Taiwan. The semiconductors in short supply at that time were 28nm logic semiconductors and MCU (Micro Controller Units, commonly known as “microcontrollers”).
The integration density of the current CPU is very high. The above functions are now integrated into the CPU and become a chip. For example, the K60 chip I am using now has these peripheral functions. The four chips of the early CPU peripherals are now integrated into one chip, so the current System is in one chip. That is, System on Chip (SoC), so theoretically there is a difference between CPU and SoC. The standard CPU refers to the early chips that only contain arithmetic units and controllers, and SoC has integrated the system into a whole chip. Therefore, the chips you buy now are all SoCs, and the standard CPUs are not too big to buy. Today’s CPUs have integrated many peripherals inside.
