Cross-platform runtime code generation for bit block transfer functions |
摘要 |
An exemplary method for performing a bit block transfer (bitblt) includes receiving one or more graphics parameters specifying the bitblt and generating a specialized bitblt function to perform the bitblt. The specialized bitblt function includes a one or more code blocks selected from a superset of code blocks based on the graphics parameters. A system includes a specialized bit block transfer (bitblt) function generator generating a specialized bitblt function to perform a specified bitblt. The specialized bitblt function includes intermediate language code corresponding to one or more graphics parameters specifying the bitblt. A translator translates the specialized bitblt function into machine-specific language code.
