A connector (20) having an assembly (28) adapted to releasably receive an end (33) of a workpiece (22). the master device of the start of data transfer; and (e) transferring data through the data bus, wherein the access command packet includes an address, a read/write flag, a bit width, and an identifier of a master device transmitting the access command packet. 7. The data transfer method of claim 5, wherein the access command packet further includes a burst length for burst transmission of data. 8. A data transfer method comprising the steps of: (a) receiving bus requests from two or more master devices and arbitrating access to an address/control bus according to a predetermined arbitration algorithm; (b) receiving an access command packet containing information for data transfer preparation from the master device through the address/control bus in the order determined as a result of the arbitration and transmitting the received access command packet to a corresponding slave device; (c) receiving notification of transfer preparation completion of corresponding data from the slave device; (d) informing the master device of the start of data transfer; and (e) transferring data through the data bus, wherein if data transfer in the step (e) aborts, the data transfer method further comprises the steps of: (h) receiving an abort indicator from the slave device; (i) informing a corresponding master device of the abort of data transmission; and (j) retransmitting the data. 9. The data transfer method of claim 8, wherein: the step (h) comprises the step of (h') receiving the abort indicator and an identifier of a corresponding master device from the slave device, and the step (i) comprises the step of (i') transmitting the abort indicator to the master device corresponding to the identifier. 10. A bus system including an address/control bus and a data bus, the bus system comprising: an arbiter for arbitrating access to the address/control bus according to a predetermined arbitration algorithm; one or more master devices which transmits, to the arbiter, an access command packet containing information for data transfer preparation through the address/control bus in an order determined as a result of the arbitration, and which receives or transmits data through the data bus upon receipt of a notice of data transfer start from the arbiter; and one or more slave devices which informs the arbiter of data transfer preparation completion, which receives and executes the access command packet, and which receives data from, or transmits data to, a corresponding master device through the data bus upon receipt of a notice of data transfer start from the arbiter. 11. The bus system of claim 10, wherein, upon receipt of a data transfer finish indicator from the slave device, the arbiter informs the master device of the finish of data transfer. 12. The bus system of claim 11, wherein the arbiter receives the data transfer finish indicator from the slave device. 13. A bus system including an address/control bus and a data bus, the bus system comprising: an arbiter for arbitrating access to the address/control bus according to a predetermined arbitration algorithm; one or more master devices which transmits an access command packet containing information for data transfer preparation through the address/control bus in an order determined as a result of the arbitration, and which receives or transmits data through the data bus upon receipt of a notice of data transfer start from the arbiter; and one or more slave devices which informs the arbiter of data transfer preparation completion, which receives and executes the access command packet, and which receives data from, or transmits data to, a corresponding master device through the data bus upon receipt of a notice of data transfer start from the arbiter, wherein, upon receipt of a data transfer finish indicator from the slave device, the arbiter informs the master device of the finish of data transfer, and wherein the slave device transmits a transfer control pac ket containing a data transfer start indicator and an identifier of a corresponding device for informing about data transfer preparation completion, and the arbiter informs the master device, corresponding to the identifier contained in the transfer control packet, of the start of data transfer. 14. The bus system of claim 13, wherein the slave device transmits a transfer control packet containing a data transfer finish indicator and an identifier of a corresponding master device, if the data transfer is complete. 15. A bus system including an address/control bus and a data bus, the bus system comprising: an arbiter for arbitrating access to the address/control bus according to a predetermined arbitration algorithm; one or more master devices which transmits an access command packet containing information for data transfer preparation through the address/control bus in an order determined as a result of the arbitration, and which receives or transmits data through the data bus upon receipt of a notice of data transfer start from the arbiter; and one or more slave devices which informs the arbiter of data transfer preparation completion, which receives and executes the access command packet, and which receives data from, or transmits data to, a corresponding master device through the data bus upon receipt of a notice of data transfer start from the arbiter, wherein the access command packet includes an address, a read/write flag, a bit width, and an identifier of a master device transmitting the access command packet. 16. The bus system of claim 15, wherein the access command packet further includes a burst length for burst transmission of data. 17. A bus system including an address/control bus and a data bus, the bus system comprising: an arbiter for arbitrating access to the address/control bus according to a predetermined arbitration algorithm; one or more master devices which transmits an access command packet containing information for data transfer preparation through the address/control bus in an order determined as a result of the arbitration, and which receives or transmits data through the data bus upon receipt of a notice of data transfer start from the arbiter; and one or more slave devices which informs the arbiter of data transfer preparation completion, which receives and executes the access command packet, and which receives data from, or transmits data to, a corresponding master device through the data bus upon receipt of a notice of data transfer start from the arbiter, wherein if data transfer aborts, the slave device transmits a transfer control packet containing the abort indicator and an identifier of a corresponding master device to the arbiter, and the arbiter transmits an abort indicator to the master device corresponding to the identifier contained in the transfer control packet.
