摘要： Methods and apparatus for storing and retrieving data in parallel but in different orders. In one implementation, data for pixels for one frame is stored according to a checkerboard pattern, alternately between two memory devices, forming a checkerboard buffer. While data is being stored, data for pixels from another frame is retrieved from another two memory devices. The banks of devices alternate between storing and retrieving with each frame. In one implementation, a checkerboard buffer includes: a data source, providing data in a first order; a data destination, receiving data in a second order; at least four memory devices, each memory device having a plurality of memory locations, where data is stored in parallel to at least two memory devices and retrieved in parallel from at least two memory devices; a first data switch connected to the data source and each of the memory devices, where the first data switch controls which data is stored to which memory device; and a second data switch connected to the data destination and each of the memory devices, where the second data switch controls providing data to the data destination according to the second order.

摘要： Data is supplied to a double buffering process. New data is supplied to a background buffer for a displayed item. A condition is identified to the effect that the item in a foreground buffer is invalid. On the previous cycle, a similar process may have been performed such that the background buffer contains invalid items. Before swapping the roles of the buffers, any invalid items in the background buffer are validated. In this way, all item transitions appear without artefacts without adding a significant overhead.

摘要： A method for enabling reduced transport display in a computer image generator connected to a host simulator which receives real-time input. The first step is performing real-time matrices calculations with the real-time input. The next step is processing geometry for primitives in a scene and storing the primitives in a double-buffered geometry buffer. The geometry buffer toggles as soon as the geometry processing is done without waiting for a field sync signal which reduces the transport delay normally found in image generation systems. Another step is rendering the primitives into a pixel frame buffer as soon as the geometry buffer toggles. The final step is displaying the pixel frame buffer. The rendering hardware and geometry processing hardware can also include enough processing power to complete the geometric transformations and rendering and in less than one display frame. Allowing the geometry and rendering to complete faster allows reduces the transport delay because the geometry buffer can toggle sooner and the pixels can be displayed sooner.

摘要： A memory architecture for a video transpose memory employs SDRAM memory devices which are arranged in memory rows such that elements in a single row may be accessed without memory set-up latency. The memory architecture includes at least two memory banks such that memory write operations to one bank may be interleaved with memory write operations to the other bank. Samples of the image along one direction are stored into the memory in groups such that corresponding samples in the orthogonal direction are held in the same memory row. The memory banks are interleaved on the store operation such that consecutive write operations access respective memory rows in the alternating memory banks. The number of samples in a group of samples is selected such that the total time for displaying the number of samples in the group is at least equal to the set-up latency of the memory. Accordingly, consecutive groups of samples may be stored into the alternating memory banks continuously. When image data are read from memory, the memory read operations are not interleaved. To compensate for the set-up latency in the read operations, the controller advances the first read operation for a particular image line or image column into the horizontal or vertical blanking interval by an amount of time equal to the total latency for the line or column. The system includes a first in first out (FIFO) buffer which receives the image data as it is provided from the memory in response to the memory read requests and provides the image data according to the output timing for the transpose memory.

摘要： A display-based system is disclosed with a processing unit, a memory control facility, and a graphics display controller interfacing to a display facility. Collectively these modules are interconnected by a bus facility to an external memory facility. The graphics display controller has a first mode providing a video image signal to the display facility. In particular, a detector is provided for detecting display stabilization. An output of the graphics display controller is being coupled to a frame grabber. The frame grabber is arranged to execute a writeback-to-memory storage of the video image signal into a writeback image memory during a subsequent videoframe, and subsequently signaling the graphics display controller to switch over to a second mode, in which the stored writeback video image signal is supplied to the display facility. The average data traffic on the bus facility is thus reduced.

摘要： A predictive optimizing unit for use with an interleaved memory and suitable for use in a computer graphics system is described. The unit maintains a queue of pending requests for data from the memory, and prioritizes precharging and activating interleaves with pending requests. Interleaves which are in a ready state may be accessed independently of the precharging and activation of non-ready interleaves.
