Abstract
Deposit and extract instructions include an opcode, a source address, a destination address, a shift number, and a K-bit mask string. The opcode describes the operations to be performed upon a J-bit source string and an N-bit destination string. The source address points to the memory location of the J-bit source string. The destination address points to the memory location of the N-bit destination string. The shift number indicates the number of bits the J-bit source string is to be shifted to generate a shifted bit string. The combination of the shifted bit string with the N-bit destination string is conducted under the control of the K-bit mask string. The invention is useful for high speed digital data processing, such as that performed by devices operating under the IEEE 1394 protocol.
