Intel introduced the 8086 microprocessor in 1978. This processor ended up being hugely influential, setting the path for the x86 architecture that is extensively used today. One interesting feature of the 8086 was instructions that can efficiently operate on blocks of memory up to 64K bytes long....
Microprocessorinterruptsare divided intofault, traporabortconditions. For fault conditions, the instruction that caused the fault is retried after the interrupt service routine has been executed. For trap conditions, the next instruction in the program being run by the CPU is executed after execution ...
A read/writable memory formed in the same semiconductor chip as a microprocessor is employed in testing a plurality of hardware interrupt service routines initiated by corresponding devices (and components of devices) during a power-on, self-test(POST) of a computer system. The POST is set in ...
In subject area:Computer Science A hardware timer in computer systems is a critical component that consists of a hardware counter. This counter counts down from a set value and triggers an event, such as an interrupt to the CPU, when it reaches zero. It is used by the operating system to...
In [12], a hardware architecture for real-time operating systems support using special hardware components implemented in one FPGA, called the F-timer, is presented. The F-Timer is a co-processor that communicates with the microprocessor and releases the processor of the tasks time management. ...
Note - The term "x86" refers to the Intel 8086 family of microprocessor chips, including the Pentium, Pentium Pro, Pentium II, Pentium II Xeon, and Celeron processors and compatible microprocessor chips made by AMD and Cyrix. In this document the term "x86" refers to the overall platform ...
