Abstract

The method includes steps: (1) obtaining the source and pattern codes by decoding instruction; (2) determining initial value of timer based on the source; (3) carrying out operations of starting, stopping and resetting timer based on pattern codes; (4) timing overflow of timer generates abnormal signal to report error. Embedding timing control unit to architecture of general processor without adding additional module, the method realizes instruction of timing control. Using one piece of instruction of timing control instead of timing operation implemented by multiple instructions usually, the invention solves issues of no response for error of asynchronous calculation as well as not ending for long time caused by error of transferring blocks with multiple addressing spaces. Features are simple structure and flexible application.

Description

technical field [0001] The invention relates to a method and a device for asynchronously computing timing control instructions in multiple address spaces. Background technique [0002] Computation-intensive applications often use a host-accelerator structure to improve computing efficiency. There is a large-scale data transmission between the host and the accelerator, and it is easy to cause the transmission process to continue for a long time due to errors in the transmission path. In addition, if there is an asynchronous calculation unit in the accelerator, the asynchronous calculation of the unit may also fail to output calculation results and response signals for a long time due to errors. For the detection of such common error problems, it is usually realized by timer programming. However, timer setting requires multiple instructions, which is complicated in applications that frequently use timers. Contents of the invention [0003] The object of the present inventi...
