Recently, a “technological breakthrough” has emerged in the circuit board recycling industry! A company in Anhui has applied for a new patent, intriguingly titled “A Device for Hydrometallurgical Recovery of Precious Metals from Waste Circuit Boards”—doesn’t the name alone make you feel like precious metals are calling out to you? In simple terms, the biggest … Read more
Introduction During the FPGA development process, it is common to encounter situations where data needs to be cached for later use. Typically, there are two solutions: RAM and FIFO. However, using FIFO has two limitations: There is a fixed delay of at least 3 clock cycles between FIFO output and input, and it cannot be … Read more
The report from Electronic Enthusiasts (by Li Wanwan) states that the NPU is a processor specifically designed for artificial intelligence (AI) computations, primarily used for efficiently executing operations related to neural networks (such as matrix multiplication, convolution, activation functions, etc.). Compared to traditional CPU/GPU, the NPU has advantages in energy efficiency and computational speed, making … Read more

Click to follow me and set as a star to receive updates immediately The academic and commercial research utilizing decision analysis models is rapidly increasing in both quantity and technical complexity. The variety of software used to implement such models is also expanding, but most modeling work is concentrated among a few software packages. In … Read more
Random signals cannot be represented by deterministic mathematical relationships and cannot predict their future instantaneous values. Any observation only represents one of the possible outcomes within its range of variation, and its value changes according to statistical laws. It is not a deterministic function of time, and there is no definite function value at any … Read more
