In a Linux system, when you enter a command and press two TAB, all available commands that begin with the characters you enter are listed. It's not new, maybe you already know. This feature is called Command line completion bash completion. By default, the Bash command line can automatically complete the file or directory name. However, we can enhance the Bash command completion function and let it reach new heights with the complete command.This tutorial shows how we can use the

After the self-test is completed, the system will look for the operating system on the specified drive and mount the operating system to memory. What are the basic features of the BIOS? Includes BIOS interrupt service program, BIOS System Setup program, post, BIOS system boot bootstrap program, etc. What is the classification of the BIOS?

Theoretically, SDN technology should bring about a safer network. Because, through virtual networks to programmable stacks, the network will become more flexible and operations should be more automated, which should mean less "fat finger" disaster. However, for any interconnected system, when we allocate basic operations to software, we also introduce new risks. When we connect servers to the internet, we know that some servers will be attacked, so we

Two independent asynchronous serial I/O ports are provided for the UART unit of the high-efficiency FIFO serial port based on the implementation of b0x (clock frequency: 60 MHz) on the ARM7, each communication port can work in the interrupt or DMA mode. That is, UART can generate an internal interrupt request or DMA request to transmit data between the CPU and the serial I/O port. It supports a transmission rate of up to 115.2 kb/s. Each UART channel contains two 16-bit first-in-first-out (FIFO)

universal broadcast address is used to simultaneously address all devices connected to the I2C bus. if a device does not need data when broadcasting an address, it can ignore it without generating a response. if a device requests data from a universal broadcast address, it can respond and act as a slave-receiver. when one or more devices respond, the host does not know how many devices have responded. each slave-receiver that can process this data can respond to the second byte. if the slave do

automatically lost after power failure. DRAM integration is much higher than SRAM, and the unit capacity is much lower. For example, the product model is 4164,41256. (2) read-only memory (read only memory. The main feature is that the stored content does not need to be maintained by the power supply, and the content will not be lost after power-off. Therefore, the content needs to be burned and written for solidification. The main purpose is to store written programs and/or relatively fixed dat

devices and external storage are also connected separately with other bus for management and data transmission bus structure. Obviously, different bus structures have different influences on the Design and Performance of the operating system.1.5.2 main registers related to the Operating SystemRegisters are closely related to the operating system because they are temporary storage devices that exchange data faster and smaller than the memory in the processor and are more expensive. The storage f

Vertex shader and fragment shader are programmable pipelines. Vertex array/buffer objects: Vertex data source. In this case, the vertex input of the rendering pipeline usually uses buffer objects.Better efficiency. In today's example, vertex array is used for simplicity; Vertex shader:Vertex shaderOperations on vertices are implemented in a programmable manner, such as coordinate space conversion and per-ve

Introduction to vertex shader pixel shader 1. Fixed-function graphics processing pipeline (fixed function graphics pipeline) The graphic processing assembly line for graphics cards that can implement vertex shader and pixel shader is called programmable. In contrast, the graphic processing assembly line before this is called a fixed function ), the following is a simplified image of OpenGL image processing: The complete OpenGL Graphic Processing asse

that the prom is one-time, that is, after the software is filled in, it cannot be modified. This is an early product and cannot be used now. The EPROM is used to erase the original program through ultraviolet radiation and is a general memory. Another type of EEPROM is to be wiped out by an electronic device. It has a high price, a long write time, and a low write speed.For example, the mobile phone software is usually placed in the EEPROM. When we call, some of the last dialing numbers are tem

needed, without considering the many PCI Bus Specifications, in this way, the complex pci bus interface relationship is transformed into a simple 8/16/32-bit plus BUS (ADD-on bus) interface relationship. Function Diagram 2 of S5933 chip is shown in. Data transmission between the PCI bus and the bus can be performed through three internal channels: first-in-first-out memory (FIFO), Mailbox register (Mailbox), and Pass-Thru. Each channel includes two sets of registers to complete two-way data t

Second, the cost of standard encapsulation of High-pin ASIC is often much larger than that of the chip itself. 7. cob Wire Bonding equipment uses cob technology to process 90% of the products from experience. 100 × 100mm printed boards are required, and each printed board chip is smaller than 100. Therefore, COB bonding equipment must meet the following minimum requirements; the minimum size of the printed board is 100x100mm. For Image Recognition, more than 200 referenc

device, this unique IRQ Number can be used to differentiate different hardware. In a computer, interruption is an electrical signal generated by hardware and directly sent to the interrupt controller. Then, the interrupt controller sends a signal to the CPU. After the CPU detects the signal, in this case, the current job is interrupted and the interrupted job is processed. Then, the processor will notify the operating system that an interruption has occurred, so that the operating system will
