Embodiments are disclosed relating to methods of ordering transactions across a bus of a computing device. One embodiment of a method includes determining a current target memory channel for an incoming transaction request, and passing the incoming transaction request downstream if the current target memory channel matches an outstanding target memory channel indicated by a direction bit of a counter or the counter equals zero. The method further includes holding the incoming transaction request if the counter is greater than zero and the current target memory channel does not match the outstanding target memory channel.

Memory transaction ordering

Packet sequence numbers of request packets and response packets of transactions transferring data to or from a network interface are tracked. For every request packet transmitted by the network interface, the packet sequence number of the packet is written to a location in a circular send queue pointed to by a write pointer and a valid bit at the location is set. The write pointer is incremented if the packet is a read request packet. Alternatively, a read indicator at the location in the circular send queue pointed to by the write pointer is cleared if the packet is not a read request packet. For every response packet received by the network interface, the packet sequence number of the response packet is checked against the packet sequence number stored at the location in the circular send queue pointed to by the read pointer of the circular send queue.

Memory utilization in a network interface

A method and apparatus for non-contiguous translation protection table that includes one or more first registers, two or more second registers, an address translator, and a detector. Each first register contains a value denoting a size of each of two or more blocks of memory. Each second register contains a value denoting the starting physical address of an associated one of the two or more blocks of memory. The address translator receives a virtual address and translates the virtual address to a physical address of one of the two or more blocks of memory. The detector detects whether the received virtual address is outside of the range of the two or more blocks of memory. The blocks of memory may be translation protection tables that reside in physically non-contiguous memory locations.
