Abstract
A method of performing a VMEbus split-read transaction (401) includes providing a master VMEbus module (102) coupled to a slave VMEbus module (104) through a VMEbus network (106). The master VMEbus module initiates a VMEbus split-read transaction request (124) in a VME address encoding phase (201) to the slave VMEbus module, where the VMEbus split-read transaction request includes a tag identifier (206, 306) in the VMEbus address encoding phase corresponding to the VMEbus split-read transaction request, where the tag identifier is unique to the VMEbus split-read transaction request, and where the VMEbus split-read transaction request requests a set of data (144). The master VMEbus module releases the VMEbus network and the slave VMEbus module acquires the VMEbus network. The slave VMEbus module places the set of data on the VMEbus network, wherein the set of data includes the tag identifier. The master VMEbus module correlates the tag identifier to the split-transaction request and the master VMEbus module retrieves the set of data.
