In the 7nm Ruilong 3000 series processor released by AMD, the Ruilong 9 3950X released on the E3 game show is the most eye-catching. The 16-core 32-thread processor itself is not unusual, but the Ruilong 9 3950X is too special. It is the mainstream AM4 platform rather than the previous TR4 platform, still able to achieve 4.7GHz under 16 cores, the official name is called the world's first 16-core game processor. What does it mean to dare to use this statement? DIY players should know that for the CPU, the more the number of cores, the less likely the frequency will be improved. The technology, power consumption, and heat are all limited, so this leads to a very embarrassing problem for the enthusiast processor. Just to prove the top-level identity, their core number is much higher than the average desktop processor, but the consequence is that their frequency is low, resulting in poor game performance. This problem is in Ruilong Threadripper, Intel Core i9 (X299 platform) Ther...

1. When using a single power supply, the VEE of the CD4051 can be connected to GND. 2. It is strongly recommended to add pull resistors to the A, B, and C three-chip select terminals. 3. Do not add filter capacitors (parallel to ground) on the common output of CD4051. Otherwise, the voltage after conversion of different channels will cause great error after being discharged by capacitor. 4. When the output terminal (INH) is disabled, all outputs are cut off, so this terminal is grounded when applied. When switching audio signals, it is best to connect a DC blocking capacitor to the input and output terminals. IO port expansion using CD4051 analog switch chip 1, CD4051 introduction For details reference: TI CD4051 Datasheet It can be understood as a single-pole 8-throw switch, the principle is as follows: CD4051 analog switch chip realizes IO port expansion Use three IOs to control the A, B, and C address pins to connect the 3 pins to t...

One of the driver's most important tasks is to observe the surrounding environment and respond accordingly. As automakers implement Advanced Driver Assistance Systems (ADAS), vision systems have drawn attention to their role. According to the National Highway Traffic Safety Administration (NHTSA), every vehicle moving on the road contains a dangerous component, the person behind the wheel. The NHTSA conducted a detailed survey of 2,189,000 road traffic accidents and concluded that 94% (2,046,000) were due to the driver's fault. The most common driver error (identification error) is due to lack of attention, or the driver is distracted in some way, which together account for 41% of the driver's accident. The safety of road users is very important. With this in mind, the world's leading car brands are constantly adding new features to their cars to help drivers drive safer or develop more advanced systems. In the long run, these advanced systems will make driving...

ATmega16 has four 8-bit bidirectional I/O ports PA, PB, PC, PD. They correspond to 32 I/O pins externally. Each bit can be used independently for the input and output of logic signals. Working at 5V At the voltage, when the output is high, each pin can output a drive current of 20mA. When the output is low, each pin can absorb a maximum of 40mA. All I/O registers of the AVR microcontrollers can be accessed in two different ways: using IN and OUT dedicated instructions that access the I/O registers or using instructions that are accessed to the SRAM. The IN, OUT instruction cycle is 1 clock. In addition, registers with the I/O register address range between $00 and $1F (the first 32) can also be used to implement bit operations and bit judgment jumps. For example: SBI (I/O register designation location 1), CBI (I/O register designation bit is cleared to 0), SBIS (I/O register designation bit is 1 jump), SBIC (I/O register designation bit is 0 jump).
