Abstract: A system and method for converting data from one format to another in a processing pipeline architecture. Data is stored in a shared cache that is coupled between one or more clients and an external memory. The shared cache provides storage that is used by multiple clients rather than being dedicated to separately convert the data format for each client. Each client may interface with the memory using a different format, such as a compressed data format. Data is converted to the format expected by the particular client as it is read from the cache and output to the client during a read operation. Bytes of a cache line may be remapped to bytes of an unpack register for output to a naïve client, which may be configured to perform texture mapping operations. Data is converted from the client format to the memory format as it is stored into the cache during a write operation.

The mechanisms allow controllable levels of detail for different rendered objects, controllable post filtering of rendered images, and controllable compression quality of each object in compressed images.

Abstract: An image processing apparatus processes compression encoded data of a moving picture and outputs image data divided into a plurality of frames for displaying of the moving picture on a display device.

At this time, a display control section executes the drawing process based on the image data stored in a ring buffer in accordance with the drawing command. Therefore, the host CPU can freely control timings at which the moving pictures are displayed on the display device.

Software overrides may be placed in applications software in systems that desire to control data decompression at the software application level.

Abstract: When a user interface is scrolled, data requests are made. If the data is not found in cache, the data is retrieved from a remote server by asynchronously placing data requests to a server starting with the last added data request. Through a relaxed loader, the mobile device does not bombard the remote server with requests. By removing older data requests, the mobile application fetches data more in line with the current display. After receiving the data from the remote server, the data is decoded and compressed. The data is placed within cache. When multiple entries exist, the data within cache is associated and processed. Instead of the interface decoding data from the cache for each entry, the processed data is provided to the interface removing processing and required memory for each entry.

Abstract: Systems and methods for determining a compression tag state prior to memory client arbitration may reduce the latency for memory accesses. A compression tag is associated with each portion of a surface stored in memory and indicates whether or not the data stored in each portion is compressed or not. A client uses the compression tags to construct memory access requests and the size of each request is based on whether or not the portion of the surface to be accessed is compressed or not. When multiple clients access the same surface the compression tag reads are interlocked with the pending memory access requests to ensure that the compression tags provided to each client are accurate. This mechanism allows for memory bandwidth optimizations including reordering memory access requests for efficient access.

Abstract: When inputted pixels from an input DMA unit, a packing unit outputs data package. One data package consists of ? inputted pixels. A memory control unit writes, on a write line memory at a write interval, the data package that is outputted by the packing unit. The write interval is ? times longer than an input interval at which the pixels are inputted into the packing unit. During the writing process, the memory control unit reads out another data package from a read line memory at a read interval that is the same as the input interval. In addition, the memory control unit treats the write line memory as the read line memory, after completing the writing process. Alternatively, the memory control unit treats the read line memory as the write line memory, after completing the reading process.

Video data for the pixel block of the video frame currently being encoded is loaded into the output buffers of the rendering pipeline. The video data for the comparison pixel blocks from the reference video frame is stored as texture map values in the texture cache of the rendering pipeline.

As each fragment is rendered, the stored and rendered fragment data is compared by fragment compare unit and the determined differences in the data values are accumulated in an error term register.
