Abstract
A method of operating a data processing system comprises maintaining record of a set of processing passes to be performed by processing pass circuitry of the data processing system. The method comprises performing cycles of operation in which it is considered whether or not the data required for a subset of processing passes is stored in a local cache. The subset of processing passes that is considered in a subsequent scan of the record comprises at least one processing pass that was not considered in the previous scan of the record, regardless of whether or not the data considered in the previous scan is determined as being stored in the cache. The method provides an efficient way to identify processing passes that are ready to be performed.
