Matrix calculator for matrix multiplication e.g. in image signal processing, sequentially calculates each element from multiplication result matrix by sequential addition

摘要

The calculator includes an element selector (70) which sequentially selects each input element that forms a multiplicand of each sub-element, and sequentially outputs the selected element. A calculation part (40) sequentially calculates each element from the multiplication result matrix by sequential additions of multiplied values. A memory stores the output from the calculation part. A control signal generator (50) controls the time sequence of the calculation part and the memory part.
