In the binary data field, and apparatus for determining the number of leading binary data bits

摘要

PROBLEM TO BE SOLVED: To discriminate the total number of pieces of preceding '0' or '1' in a binary data field, especially, in a fixed-size field. ;SOLUTION: A device for discriminating the number of preceding binary data bits incorporates a plurality of detector circuits which input the different sections of a binary data field. During the course of preceding '0' detecting operations, each detector circuit discriminates the bit position containing the highest-order '1' of the binary data field and outputs a binary number signal indicating the number of '0' preceding the highest-order '1'. The detector circuit also discriminates whether or not each bit position in the section which is inputted by the circuit itself contains '0', and outputs a zero detecting signal indicating the state. The binary number signal and zero detecting signal respectively generate a binary number signal indicating the number of preceding '0' in a complete binary field and a zero detecting signal indicating whether or not all bit positions in the complete binary field contain '0'.;COPYRIGHT: (C)1996,JPO
