Functional Description and Application Information
Each module has individual control and configuration registers that are accessed via the IP interface, and
are capable of bus mastering the AMBA bus to independently access system memory without any CPU
intervention. This enables each module to be used independently of each other, and enables the
pre-processor and post-processor modules to provide acceleration features for other software codec
implementations and image processing software. These blocks work together to provide video
acceleration, and to off-load the CPU from computation intensive tasks. The PrP and PP can be used for
generic video pre- and post-processing, such as scaling, resizing, and color space conversions. A
32-bit-to-64-bit AHB gasket is used to convert a PrP AHB bus from a 32-bit to 64-bit protocol. A bypass
function is implemented to bypass this 64-bit gasket if it is not needed.
