SRAM BASED ADDRESS GENERATOR FOR EACH LAYER AND ADDRESS GENERATOR INCLUDING THE SAME

摘要

An SRAM based address generator is provided, which can perform a TCAM function that returns an address of data when the data is input. The address generator includes n bit position tables receiving n input sub-words each of which is composed of w bits and outputting bit position data of addresses indicated by (w-b) bits of the respective sub-words, last index data, and bit values indicated by b bits of the sub-words among the bit position data; a first AND operation unit receiving and performing an AND operation of the n bit values and outputting n enable signals; n address generators receiving the bit position data, the last index data, and the enable signals and outputting address data; n address position tables receiving the address data and outputting address position data of the addresses indicated by the address data; and a second AND operation unit receiving and performing an AND operation of the n address position data and outputting first matching addresses.
