Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] The first embodiment of the present invention relates to an interrupt processing method, the specific process is as follows figure 2 shown.

[0034] Step 210, input interrupts, and aggregate the input interrupts into a group of interrupts.

[0035] Step 210 includes:

[0036] Step 2110, when there is an interrupt input, sample the input interrupt.

[0037] In step 2110, the input interrupt may be sampled in a level-triggered or edge-triggered manner. When there is an interrupt input, convert the interrupt into a high level or rising edge, that is, a high pulse signal.

[0038] Step 2120, perform logic processing on the high pulse signal in step 2110 and the corresponding bit in the latch.

[0039] Here, when the bit position of the ...

Abstract

An interruption treatment comprises the polymerization of interruption into a group, with the processor read a group of interruption for treatment. It also provides an interruption processor that comprises the interruption input unit, polymer unit, timing unit, signal generation unit and interruption processor. It also provides an interruption processor that comprises the interruption input unit, polymer unit, timing unit, signal generation unit and interruption processor. The interruption treatment method and device avoids the frequent interruption of processor, saving the expenses for treating it.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a method and device for processing interrupt information. Background technique [0002] Interruption refers to a reaction made by the processor to a certain event that occurs in the system, that is, the processor suspends the program being executed, automatically transfers to the corresponding processing program after saving the scene, and returns to the breakpoint to continue after processing the event Execute the program that was "interrupted". [0003] Traditional interrupt handling includes: interrupt source, interrupt controller and interrupt handler. Events that cause interrupts are called interrupt sources. The interrupt controller selects the corresponding interrupt to report to the interrupt processor according to the priority level, and the interrupt processor selects and enters the corresponding interrupt processing program according to the type of the int...
