Sažetak
A high speed modular masking circuit having utility in field extraction, bit checking, and other like operations includes a plurality of input address lines for receiving binary numerical representations, two control lines, and a plurality of output masking lines, the number of output lines being equal in number to two raised in power to the number of input lines. When both control lines are at the same binary logic level, that level is likewise present on all output lines. When otherwise, a number of contiguous ones or zeroes are present on the output lines starting at the first output line, the number of ones or zeroes being equal to the binary numerical representation present at the input address lines and the number being either ones or zeroes depending upon the logic levels present on the control lines. The modular masking circuit is adaptable to various embodiments suitable for SSI, MSI, and LSI. Furthermore, the modular aspect of the masking circuit permits universal application over a wide range of masking tasks.
