Abstract
PURPOSE:To increase an operation speed, by multiplying and adding an output of an index memory, and a signal indicating an increment. CONSTITUTION:When connecting information between each operation element is provided as a read address designating signal, to DELTAZ memories MZ1-MZ4 storing an operation result, from connection memories MC1-MC4, contents of the DELTAZ memories MZ1- MZ4 which have been read out become an increment signal of the operation result, and are provided to multipliers ML1-ML4 as an operation input. On the other hand, since an index value of an index bit from index memories MI1- MI4 is also provided to the multipliers ML1-ML4, the operation input is multiplied by the index value, its result is added to the first adder AD1, its output is digit- shifted, is added to the result of addition which has been executed immediately before, and when the increment is quantized by an outputting circuit OZ and has become a constant value, it is stored in the DELTAZ memories MZ1-MZ4, and is used as an input of the next operation.
