Optimized function assignment in a multi-core processor

A method comprising:

• receiving a user application, wherein the user application includes a set of functions;
• simulating execution of different configurations of the set of functions on a multi-core microprocessor chip, wherein:
• the multi-core microprocessor chip comprises a set of tiles arranged in a grid configuration, wherein each tile comprises a processor core and a corresponding router, wherein each router:
• is communicatively coupled with at least one other router to form a network-on-chip, and
• implements the same deterministic static priority routing policy, wherein the deterministic static priority routing policy comprises assigning unchanging priority levels to the input ports of the router and routing outbound data in accordance with the unchanging priority levels, and
• the different configurations include execution of the set of functions by different groups of tiles;
• monitoring network traffic patterns of the execution of the different configurations;
• ranking the different configurations according to ranking criteria, wherein the ranking criteria is used to rank each of the different configurations based on the corresponding network traffic patterns;
• and
• selecting an optimal configuration of the different configurations based on the ranking.

A method comprising:

• receiving a user application, wherein the user application includes a set of functions to be executed by a multi-core microprocessor chip, wherein the multi-core microprocessor chip comprises a set of tiles each including a processor core and a corresponding router, wherein each router:
• is communicatively coupled with at least one other router to form a network-on-chip grid, and
• implements the same deterministic static priority routing policy, wherein the deterministic static priority routing policy comprises assigning unchanging priority levels to the input ports of the router and routing outbound data in accordance with the unchanging priority levels;
• receiving an identification of a high priority function of the set of functions;
• identifying one or more tiles with high routing priority according to the static priority routing policy;
• assigning execution of the high priority function to the one or more tiles with high routing priority;
• and
• executing the high priority function in accordance with the assignment.
