Fig. 2: Typical external circuits: AX14-Stream IPs Fig.5: Format of Public Data Input (PDI), Secret Data Input (SDI), Random Data Input (RDI) and Public Data Output (PDO) for encryption and decryp- tion. Table 2: Segment Type Encoding The segment header format is shown in Fig. 9. The segment header consists The instruction/status format of the PQC HW API is shown in Fig. 8. For instruction, the Opcode field determines which operation should be executed next. Alternatively, for status, the Opcode field is replaced by the Status field, which can be set to only two values, PASS or FAIL. Fig. 10: Example timing diagram for PDI Figures 10 and 11 specify the timing characteristics of the ports PDI and PDO, respectively. Input ports are shown in blue and the output ports in red. The contents of data buses are read and acknowledged when *_valid and its corre- sponding *_ready are both asserted. Data is assumed to be present at the output of the source module when *_valid is asserted. Fig. 11: Example timing diagram for PDO
