5 / 8 page Optimized for 5 TM Table 2: CS5010-40 DES/3DES Cores Interface Signal Definitions Signal I/O Width (Bits) Description D I 32 (64 Ultra High Speed) Input Plaintext/Ciphertext data DADDR I 1 (Ultra Compact) 2 (Compact) 3 (High Speed) 0 (Ultra High Speed) Input Plaintext/Ciphertext data address, 0: the lowest 32-bit word DLOAD I 1 Load input Plaintext/Ciphertext enable KEY I 28 (56 Ultra High Speed) Encryption key data KADDR I 2 Encryption key address, 0: the lowest 28-bit word KLOAD I 1 Load encryption key MODE I 1 Encryption/Decryption mode select, 0: Encryption. 1: Decryption TRIPLE I 1 DES/3DES mode select, 0: DES, 1:3DES EDE I 1 Triple DES key selection mode, 0:EDE2, 1: EDE3 CLK I 1 System clock, rising edge active RST I 1 Asynchronous reset DSTAT O 1 Input port status This signal will be Asserted when the core is ready for loading the highest word of the next 64-bit data block, or the highest word of the multiple input DES blocks available in the Compact or High Speed cores. The lower words can be loaded at anytime in the period when DSTAT is LOW depending on the key-size selection QSTRB O 1 Output strobe indicating the Plaintext/Ciphertext word Q is valid QADDR O 1 (Ultra Compact) 2 (Compact) 3 (High Speed) 0 (Ultra High Speed) Output Plaintext/Ciphertext data address, 0: the lowest 32-bit word Q O 32 (64 Ultra High Speed) Output Plaintext/Ciphertext data |
