Network Processor and Related Instruction Scheduling Method

An instruction scheduling method comprising:

• separately obtaining, by a plurality of scheduling controllers in a network processor, a first quantity of instructions from one of a plurality of non-empty cache queues of a plurality of cache queues;
• separately generating, by the scheduling controllers, a scheduling request based on first indication information of the first quantity of instructions from each of the non-empty cache queues to obtain a plurality of scheduling corresponding to the non-empty cache queues, and wherein the first indication information indicates a scheduling mode of the first quantity of instructions;
• sending, by the scheduling controllers, the scheduling requests;
• and
• receiving, by a scheduler in the network processor, the scheduling requests from the scheduling controllers;
• sending, by the scheduler, to at least one scheduling controller of the scheduling controllers in response to the scheduling requests, at least one scheduling response signal indicating a to-be-scheduled target cache queue and a target scheduling mode of the first quantity of instructions;
• responding, by the at least one scheduling controller, to the at least one scheduling response signal, and,
• generating, by the at least one scheduling controller, a to-be-executed instruction word based on the first quantity of instructions in the target cache queue and the target scheduling mode.

A chip comprising:

• a network processor comprising:
• a plurality of cache queues comprising a plurality of non-empty cache queues;
• a plurality of scheduling controllers configured to:
• separately obtain a first quantity of instructions from one of the non-empty cache queues;
• separately generate a scheduling request based on first indication information of the first quantity of instructions, to obtain a plurality of scheduling requests corresponding to the non-empty cache queues, and wherein the first indication information indicates a scheduling mode of the first quantity of instructions;
• and
• send the of scheduling requests;
• and
• a scheduler configured to:
• receive the scheduling requests from the scheduling controllers;
• and
• send, to at least one scheduling controller of the scheduling controllers in a response to the scheduling requests, at least one scheduling response signal indicating a to-be-scheduled target cache queue and a target scheduling mode of the first quantity of instructions, and
• wherein the at least one scheduling controller is configured to:
• respond to the at least one scheduling response signal;
• and
• generate a to-be-executed instruction word based on the first quantity of instructions in the target cache queue and the target scheduling mode;
• and
• a power supply circuit configured to supply power to the network processor.
