quadword

Four contiguous words (64 bits) starting on any addressable byte boundary. Bits are numbered 0 to 63. (Bit 63 is used as the sign bit.) A quadword is identified by the address of the word containing the low-order bit (bit 0). The value of a signed quadword integer is in the range -2**63 to 2**63-1.
