Apparatus, systems, and methods for providing computational imaging pipeline

A method for operating a parallel processing system, the method comprising:

• providing a plurality of processing elements including a first processing element and a second processing element, wherein each of the plurality of processing elements is configured to execute instructions;
• providing a memory subsystem comprising a plurality of memory slices including a first memory slice associated with the first processing element, wherein the first memory slice comprises a plurality of random access memory (RAM) tiles each having individual read and write ports;
• receiving, by an arbitration block associated with one of the plurality of RAM tiles via a local interconnect of an interconnect system, a first memory access request from the first processing element;
• and
• sending, by the arbitration block via the global interconnect, a first authorization message to the first processing element to authorize the first processing element to access the one of the plurality of RAM tiles.
