D_A) to re-entrant processor 610A. Within re-entrant processor 610A, instruction buffer 613 outputs the instruction (e.g., INST_RE2) addressed by INAD_A to instruction decoder 612, which decodes the instruction to generate CTR and PC. CTR, which initiates a compare operation with data stored in the CAM arrays selected by REQ_A, is provided to CAM core 230.
