Abstract: A system and method for reordering data fragments to facilitate reads from a DDR SDRAM where the fragments are placed into a first and second data fragment buffer such that the data fragments are in sequential addresses whereby the second data read on the trailing edge of the clock cycle will read the proper data fragment.
Abstract: A system and method for generating random coverage masks for rendering images with transparent objects. The system uses shuffle tables for addresses of a pixel to index into a transparency table and to obtain a transparency mask, which is then ANDed with a coverage mask to obtain a new coverage mask.
Abstract: A radiotelephone system having DCCH channels includes an over-the-air activation teleservice sub-system (OTAF) for programming mobile stations (MS) with Intelligent Roaming (IR) information. Each MS includes a history list containing the most recently used DCCHs. The IR information sent to a MS includes data for setting the number of entries in the history list, data for setting the content of the history list entries, and a data for setting the power level threshold. The number of entries in each MS can be optimally set according to the number of DCCHs in a network with networks having a greater number of DCCHs being able to place a greater number of entries in the history list of their subscribing MSs. The content of the history list, moreover, may be optimally set for a network and for a particular cell or group of cells in a network. Thus, for instance, an MS entering a new network can be programmed to have the DCCHs of the new network. The power level threshold is used by the MS to detect suitable DCCHs.
