Abstract
With N-bit mask bit data, a bit mask generator generates (L.times.M.times.N)-bit mask data in which the N-bit mask bit data is disposed in one of L.times.M consistent blocks which is specified by M-bit block selection data and L-bit super-block selection data and each bit of the other blocks are stuffed with a stuffing bit. The bit mask generator comprises a first mask generator responsive to the block selection data for generating first mask data by disposing the N-bit mask bit data in one of M blocks of N bits which is specified by one of the M-bit block selection data, and a second mask generator responsive to the super-block selection data for generating the final mask data by disposing the first mask data in one of L super-blocks of M blocks which is specified by one of the L-bit super-block selection data. A bit field operation is performed by using the generated mask data.
