US 2011/0235936 A1 · ROUTABLE IMAGE PIPELINE DEVICE

Abstract

An image pipeline device is used for processing an image. The device comprises an external memory, a direct memory access (DMA), an image pipeline controller, and a filter layer. The image pipeline controller comprises a physical memory allocation (PMA) having a physical buffer unit, and a first array controller for configuring the physical buffer unit as a corresponding first logic buffer unit. The filter layer comprises a first filter set electrically connected to the first array controller correspondingly and having a plurality of filters. The first filter set receives the image through the first array controller, processes the image selectively according to the first logic buffer unit and the filters, and stores the processed image back to the external memory through the DMA.

Dependent claims

A routable image pipeline device, suitable for processing at least one image, comprising:

an external memory, storing the image;
a direct memory access (DMA), electrically connected to the external memory;
an image pipeline controller, comprising:
a physical memory allocation (PMA), having at least one physical buffer unit;
and
a first array controller, electrically connected to the PMA and the DMA, wherein the first array controller configures the physical buffer unit as at least one first logic buffer unit according to memory address configuration setting, and receives the image through the DMA;
and
a filter layer, comprising a first filter set having a plurality of filters, wherein the first filter set is electrically connected to the first array controller, receives the image through the first array controller, processes the image selectively according to the first logic buffer unit and the filters, and stores the processed image back to the external memory through the DMA.
