Microprocessor interrupts are divided into fault, trap or abort conditions. 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 ...
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 ...
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....
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 ...
discovered the vulnerability and turned it into a local privilege escalation exploit. The vulnerability arose because of the way OS developers implemented hardwaredebuggingcommands for Intel x86-64 architectures. When Intel released its 8086 16-bit microprocessor chip in 1978, it added a special ...
interrupt will be generated. A timer may also be configured as a one-shot timer; this mode can be thought of as creating a single shot. When a timer is set up for nonperiodic mode, it generates an interrupt when the value in the main counter matches the value in the timer’s ...
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. ...
