COMPUTING DEVICES WITH INSTRUCTION QUEUES AND PROCESSING-ELEMENT ARRAY CONTROLLERS
An example device includes single instruction, multiple data (SIMD) processing elements arranged in arrays. Array controllers are connected to the arrays of processing elements to control the arrays of processing elements to execute instructions in a SIMD fashion. An instruction queue is connected to an array controller. The instruction queue queues a sequence of instructions and dequeues the sequence of instructions to the array controller. Multiple instruction queues may be used. A main controller provides sequences of instructions to the instruction queues.
1 . A device comprising:
a plurality of single instruction, multiple data (SIMD) processing elements, the plurality of processing elements arranged in arrays of processing elements;
a plurality of array controllers, each array controller connected to an array of processing elements and configured to control the array of processing elements to execute instructions in a SIMD fashion;
a plurality of instruction queues, each instruction queue connected to an array controller, each instruction queue configured to queue a sequence of instructions and dequeue the sequence of instructions to the array controller; and
a main controller configured to provide sequences of instructions to the plurality of instruction queues.
2 . The device of claim 1 , wherein the main controller is configured to process one thread to provide the sequences of instructions.
3 . The device of claim 1 , wherein the main controller is configured to process a plurality of threads to provide the sequences of instructions.
