Two dimensional rotation of sub-sampled color space images |
摘要 |
In a method and system for controlling rotation of a color image stored as sub-sampled image data in a memory, a controller includes a finite state machine (FSM) operable to fetch the sub-sampled image data and provide the sub-sampled data as a plurality of pixels to form the color image having a predefined angle of rotation. The FSM provides a predefined address of sub-sampled image data describing the color image stored in the memory to an addressing unit. The addressing unit is operable to read twice the sub-sampled image data located at the predefined address. A memory device is operable to push each read instance of the sub-sampled image data. A pipeline controlled by the FSM is operable to pull and selectively read the sub-sampled image data from the memory device for generating the plurality of pixels.
