Problems solved by technology

This method can control the execution time of instructions whose completion time is unknown within a predetermined time, but the operation of the monitoring routine also consumes processor resources, which is equivalent to the processor being in a load state, so unnecessary energy consumption

Embodiment 2

[0026] The other modules in the second embodiment are similar in principle to the corresponding modules in the first embodiment. As described above, the instruction is executed by the execution module 303 after being prefetched and decoded. In the instruction processing device according to this embodiment, the execution module 303, in addition to executing the instruction itself, also loads the value corresponding to the data in the "timeout" data field in the instruction into the timer module 311, and starts the timer module 311 makes it start timing; on the other hand, the execution module 303 sends an adjustment start signal to the prefetch control module 312. The prefetch control module 312 can stop the prefetch module 301 by changing the enable signal of the prefetch module 301 or mask the clock of the prefetch module 301, or it can reduce the clock frequency of the prefetch module 301 to make the prefetch module 301 work. Work at a lower frequency.

Abstract

The invention discloses a device and a method for processing instruction and an executive control device used by same. The device for processing instruction uses a hardware timer to control the executive time of the instruction and adjusts the instruction processing device to be operated in the state of low energy consumption in the executive period of the instruction by adjusting a clock of the instruction processing device or adjusting the work state of a prefetching module of the instruction processing device.

Description

Technical field [0001] The present invention relates to computer technology, and more specifically, to a device and method for processing computer instructions. Background technique [0002] In a computer, the execution time of certain instructions is not only relatively long, but also unpredictable. For example, input / output (I / O, Input / Output) instructions, the time required to complete them depends on many external factors, such as in the case of multiple devices sharing a bus, you must wait until the bus is free to complete the current I / O instruction. In other words, the completion time of the I / O instruction is unknown to the processor. For this type of instruction whose completion time is unknown, if the instruction is issued and the subsequent work is waited until the instruction is completed, it will cause unstable performance. Therefore, a certain treatment method is needed to deal with this situation. [0003] One processing method is that after issuing this type of...
