Character-driven first step-a small attempt

I want to write a fully functional character driver, but I still have to consider it. Record your initial attempt to drive the character In the absence of an operating system, you need to do the following to make the system respond to the keyboard: 1. Writing a keyboard interrupt program: When you press the key, the program will enter 2. Initialization of 8259a: When you press the key, the 8259a hardware is interrupted, allowing the CPU to enter the keyboard interrupt program 3. In the interrupt

NET Web application, a single class was used both to display output and to respond to User input. Writing automated tests for Web forms-based ASP. Applications can complex, because to test a individual page, you m UST instantiate the page class, all its child controls, and additional dependent classes in the application. Because so many classes is instantiated to run the page, it c

Data Transmission commands ── ─ they transmit data between the storage and registers, registers and input and output ports. 1. general data transmission commands. moV transfers words or bytes. movsx first extends the symbol and then transmits it. movzx is not extended before transmission. push pushes words into the stack. pop pops up the word stack. pusha pushes ax, CX, dx, BX, SP, BP, Si, di into the stack in sequence. popa pops up the stack of DI, Si, BP, SP, BX, dx, CX, and ax in sequence.
