The method comprises a channel receiving a status packet indicating a device is no longer busy. The method also includes specifying whether the channel intends to re-initiate a channel program that previously resulted in the device busy status. If the channel does not intend to re-initiate the channel program, a first combination of bits in a re-initiate field of a status-acceptance packet are set which indicate that the channel will take no further action. If the channel intends to re-initiate the channel program, a second combination of bits in the re-initiate field of the status-acceptance packet are set, indicating that the channel will re-initiate the channel program. The method further includes transmitting the status-acceptance packet to a control unit. The invention also includes a system and a storage medium. | 08-28-2008 |

A picker associated with respective FIFO(s) begins an empty arbitration packet that includes a location for each output port and fills one or more locations in the packet, such as based on a prioritization scheme. Each packet is passed in a ring to another picker, which performs a fill that does not conflict with previously filled locations in that packet. Each picker has an opportunity to place requests in each of the packets. Results of the arbitration are dispatched to reorder buffers associated with respective output ports and used to schedule the interconnect. Each arbitration cycle thus produces a set of control information for an interconnect to be used in subsequent data transfer steps. | 09-18-2014 |
