From its launch in 2004 to 2008, Loongson had a difficult journey. Not only did it have to face the strong advantages of Intel and AMD, but it also had to face various domestic doubts. As a Chinese ch...
Multi-output power supplies generally use a closed-loop PWM control method for one output, while other auxiliary outputs use indirect voltage regulation. Since only the main output is closed-loop cont...
The English textbook for computer organizational structure performance design gave a memory design diagram, which is roughly translated as follows: 128K x 8SRAM 1Mb x 1DRAM 256KB x 4DRAM (all three mu...
Dual network cards are redundant and fault-tolerant, with the same IP and MAC address. One is working and the other is hot standby. When switching is needed, passthru obtains the MAC address of one ne...
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
