Abstract:
The present disclosure relates performing of comparisons between a first and a second vector. The memory location has a size or length of m bits. A compare block to compare two single bits is used. The compare block comprises: two input bits associated to one of the bits from the first and the second vector respectively; a greater than input bit and a lower than input bit; a cascade enable input bit to control if the greater than input bit and the lower than input bit are considered; a greater than result bit, a lower than result bit, and an equal result bit. A daisy chaining of m of the one-bit compare blocks is performed such that the result bits of one compare block represents the compare result of the previous compare blocks in the chain.
