A computer implemented method of rasterizing a page in a page description language efficiently utilizes the resources of a multiprocessor integrated circuit by spawning of subtasks from a RISC type processor to one or more DSP type processors. The RISC type processor interprets the page in the page description language and detects a Y coordinate of edge intersection using the floating point calculation unit. The DSP type processors sort polygon edges in increasing Y coordinate and detect a Y coordinate of edge intersections via successive midpoint approximation using an integer multiplier unit.
