Abstract
Apparatus, systems and methods for providing rasterizer driven cache coherency are disclosed. In one implementation, a system includes at least one rasterizer capable at least of identifying a rendering order conflict between first and second portions of pixel data and of generating one or more indicators of the rendering order conflict, at least one memory responsive to the one or more indicators and at least capable of retaining memory contents associated with the first portion of pixel data in response to the one or more indicators, and a display processor responsive to the rasterizer and at least capable of displaying image data resulting, at least in part, from rasterization of the first and second portions of pixel data.
Claims29
A method comprising:
- identifying a rendering order conflict between at least a first pixel span and a second pixel span;
- and
- retaining, in response to the identification of the rendering order conflict, one or more portions of memory content associated with the first pixel span.
A system comprising:
- at least one rasterizer capable at least of identifying a rendering order conflict between first and second portions of pixel data and of generating one or more indicators of the rendering order conflict;
- at least one memory responsive to the one or more indicators, the memory at least capable of retaining memory contents associated with the first portion of pixel data in response to the one or more indicators;
- and
- a display processor responsive to the rasterizer, the display processor at least capable of displaying image data resulting, at least in part, from rasterization of the first and second portions of pixel data.
A device comprising:
- at least one rasterizer capable of at least generating control data indicating a rendering order conflict between first and second pixel spans to be rasterized;
- and
- cache memory at least capable of retaining memory content associated with the first pixel span in response to the control data.
An article comprising a machine-accessible medium having stored thereon instructions that, when executed by a machine, cause the machine to:
- identify a rendering order conflict between at least a first pixel span and a second pixel span;
- and
- retain, in response to the identification of the rendering order conflict, one or more portions of memory content associated with the first pixel span.
