METHOD AND SYSTEM FOR PROCESSING INPUT DATA THROUGH DATA PROCESSOR PIPELINE

摘要

PROBLEM TO BE SOLVED: To make it possible to use plural threads for the graphics pipeline of an image rendering system by using local variables which are accessible to both a master thread and a slave thread for a step wherein an input buffer is allocated and a step wherein it is decided whether or not the input buffer can be allocated. SOLUTION: When there is no slave thread, a slave thread is generated and the input buffer is allocated to the slave thread for processing. When a slave thread is already present, the input buffer is allocated to the slave thread and when the input buffer can not be allocated, the input buffer is allocated to the main thread for processing which is performed in parallel to a process performed by the slave thread. The local variables which are accessible to both the main thread and slave thread are used for the step for allocating the input buffer and the step for deciding whether the allocation is possible. In a graphics task, a local variable set 32 stores variable flags, which can be set and reset by the main thread or slave thread.
