摘要
An array of N processing units (PU) each has: an accumulator; an arithmetic unit performs an operation on first, second and third inputs to generate a result to store in the accumulator, the first input receives the accumulator output; a weight input is received by the second input to the arithmetic unit; a multiplexed register has first and second data inputs, an output received by the third input to the arithmetic unit, and a control input that controls the data input selection. The multiplexed register output is also received by an adjacent PU's multiplexed register second data input. The N PU's multiplexed registers collectively operate as an N-word rotater when the control input specifies the second data input. Respective first/second memories hold W/D rows of N weight/data words and provide the N weight/data words to the corresponding weight/multiplexed register first data inputs. A sequencer controls the multiplexer and memories.
