IMAGE FORMING APPARATUS AND RECORDING MEDIUM SUITABLE FOR IMAGE FORMING PROCESSING BASED ON PDL (PAGE DESCRIPTION LANGUAGE)
First Claim
1. An image forming apparatus comprising:
- a first rendering core for executing data analysis of an object of PDL format printing information;
a second rendering core for starting a speculative process for generating a Display List for the object before the data analysis is completed; and
a third rendering core for executing a rendering process based on the Display List generated by the second rendering core;
whereinthe data analysis by the first rendering core and the speculative process by the second rendering core are executed in parallel processing.

Abstract
Provided is an image forming apparatus for further speeding up an image forming process. A first rendering core of a rendering core module executes data analysis of an object of PDL format printing information. A second rendering core executes a speculative process for generating a Display List for an object. A third rendering core executes a rendering process for a printout or display output based on the Display List generated by the second rendering core. In addition, data analysis by the first rendering core and the speculative process by the second rendering core are executed in parallel processing. As a result, the second rendering core can execute the generation of a Display List by a speculative process even without receiving a rendering command from the first rendering core.

4. A recording medium that is a non-transitory computer-readable recording medium for storing an image forming program executable on a computer of an image forming apparatus, and when the computer executes the image forming program:
-
a first rendering core executes data analysis of an object of PDL format printing information; a second rendering core starts a speculative process for generating a Display List for the object before the data analysis is completed; and a third rendering core executes a rendering process based on the Display List generated by the second rendering core;
