The role of an interrupt handler is to give feedback to its device about interrupt reception and to read or write data according to the meaning of the interrupt being serviced. The first step usually consists of clearing a bit on the interface board; most hardware devices won't generate ...
When the “Interrupt request” pin is raised, the microprocessor will disable further interrupts. It will then set the controller to point to the correct entry in the vector table and execute that instruction, which will alter the controller to point to the interrupt handler. Once in the interr...

Until version 2.6, Linux had been non-preemptive, meaning that when a process is running in kernel mode, if any higher-priority process arrives in the ready-to-run queue, the lower-priority process cannot be preempted until it returns to user mode. But, an interrupt is allowed to divert...
shows in functional terms how the 80386 microprocessor translate a linear address to a physical address when paging is enabled. The processor uses the upper 10 bits of the linear address as an index into the directory. The selected directory entry contains the address of a page table. The ...
andres_dalmati 5 年多前 in reply to Ralph Jacobi Expert 1080 points Hi, I have another doubt. How can I improve the USB data transfer speed? I can download with a ~330kb/s. Supposedly the microprocessor has USB 2.0, but this velocity does not correspond with that. Thanks in advance...
“independent” of the interrupt signals meaning that the MCP input to the processor is not disabled when the interrupts are disabled. As one of ordinary skill in the art should appreciate, any signal that is independent of the interrupt can be used; the MCP pin is an example of a ...
microprocessor, the method comprising: arranging the disk data channel, the host interface data channel, and the microprocessor channel into a round-robin circular priority queue; assigning the disk data channel a highest priority for buffer access requests in the queue; conducting an arbitration ...
1. A processor, comprising: a memory decoder to monitor a predetermined memory block allocated to a device; an interrupt controller to receive an emulated message signaled interrupt (MSI) signal from the memory decoder in response to a posted write transaction to the predetermined memory block init...
