2. The method of claim 1 further comprising the steps of: (g) reading the predicate from the location in the system memory included in said block fetched from said system memory; (h) causing the control unit to generate predicate evaluation instructions based on said predicate read from said system memory; (i) loading the predicate evaluation instructions into a preselected one of the processing elements; and (j) causing the preselected one of the processing elements to process the predicate in accordance with the predicate evaluation instructions.
