  • Many-to-one mapping hash address generator
    Patent number: 4642793
    Abstract: A data transformation circuit transforms an input data value into an output value according to a many-to-one mapping scheme by utilizing a hash coding circuit (30) which combines the input data value with a hashing key and a feedback signal. The hashing key is selectively variable and the output of the hash coding circuit is distributed in a selectively variable manner into one of a number of sections of a register (31) to enable the transformation to be modified in a flexible manner.
