There are various architecture alternatives regarding to different system levels when implement a pc based system . the choice must be made by taking into account the factors such as the requirement of the application , the final performance of the target system , the cost , upgradability and scalability of the target system 以pc架構(gòu)的多投影沉浸式虛擬環(huán)境在各系統(tǒng)層次上有不同類型的實現(xiàn)方案,系統(tǒng)的最終實現(xiàn)應(yīng)在考慮所需應(yīng)用的基礎(chǔ)下,權(quán)衡最終系統(tǒng)的整體性能、系統(tǒng)成本以及系統(tǒng)的可擴展性和可升級性,對各種可實現(xiàn)方案進行選擇。
With the development of general - purpose processors and high efficient algorithms , it is possible to implement a software - based real - time video encoder , and its low cost and easy upgradability attract developers " interests to migrate video encoding from dedicated hardware to more flexible software 對于實時視頻應(yīng)用環(huán)境,視頻編碼以往大多由專用設(shè)備完成。但隨著通用處理器和數(shù)字信號處理器( dsp )主頻的提高、面向視頻處理的指令集出現(xiàn),使得更為經(jīng)濟、靈活的軟件編碼成為可能。
