Processor and task processing method therefor, and storage medium

A processor, comprising:

• a scalar calculation module, a vector calculation module and a Parameter Buffer (PBUF), wherein the vector calculation module comprises:
• a shadow register and a work register;
• the scalar calculation module is configured to execute parameter calculation for a present task, store parameters obtained by calculation into the PBUF, when parameter calculation for the present task is completed, execute a first instruction or a second instruction configured for inter-core synchronization and store the first instruction or the second instruction into the PBUF;
• the shadow register is configured to read the parameters out from the PBUF and store the read parameters;
• the work register is configured to store all modified parameters in the shadow register within one cycle when the first instruction or the second instruction is read out from the PBUF;
• and
• the vector calculation module is configured to execute vector calculation for the present task according to the parameters in the work register.

A non-transitory computer-readable storage medium, the storage medium storing computer programs that, when executed by a processor, causes the processor to execute a task processing method for the processor, the task processing method for the processor comprising:

• executing parameter calculation for a present task, storing parameters obtained by calculation into a Parameter Buffer (PBUF), when the parameter calculation for the present task is completed, executing a first instruction or a second instruction configured for inter-core synchronization, and storing the first instruction or the second instruction into the PBUF;
• reading the parameters out from the PBUF, storing the read parameters into a shadow register, and when the first instruction or the second instruction is read out from the PBUF, storing all modified parameters in the shadow register into a work register within one cycle;
• and
• executing vector calculation for the present task according to the parameters in the work register.
