Abstract
PURPOSE:To improve the throughput rate and to miniaturize a device by providing pairs of one-bit or several-bit comparators in accordance with a bit length and simultaneously comparing a value to be decided with range values A and B and controlling transmission of comparison results. CONSTITUTION:The input value to be decided is inputted to comparators 14a and 14b by an input line 11. At this time, the value to be decided is previously delayed by every one cycle in order from the left of data bits synchronously with the clock signal from a clock generator 20. The leftmost bit data of the input value to be decided is inputted to two comparators 14a and 14b and is compared with range values A and B. Comparison results are inputted to a control circuit 13 by signal lines 15 and 16, and two '0' signals are sent to comparators 14 in the next stage synchronously with the clock signal from the clock generator 20. Bit data of the second stage is inputted to comparators 14 one cycle behind, and results from comparison with range values A and B are outputted to lines 15 and 16. Hereafter, the comparison processing is successively advanced to right bits similarly. The decision result is outputted from an output line 19.
