Abstract: A method of preparing a command stream for a parallel processor, comprising: analysing the command stream to detect at least a first dependency; generating at least one timeline dependency point responsive to detecting the first dependency; determining a latest action for the first dependency to derive a completion stream timeline point for the first dependency; comparing the completion stream timeline point for the first dependency with a completion stream timeline point for a second dependency to determine a latest stream timeline point; generating at least one command stream synchronization control instruction according to the latest stream timeline point; and providing the command stream and the at least one command stream synchronization control instruction to an execution unit of the parallel processor.
