我們針對高解析度H.264先進影像壓縮技術中的幅內與幅間模式選擇器提出了高效能的硬體架構。我們的方法和H.264先進影像壓縮技術的參考軟體有著一樣的影像壓縮品質。在我們的幅內模式選擇器中，我們採用了創新的資源共享機制來支援多幅參考。使用臺灣積體電路製造股份有限公司的0.13微米製程技術來合成我們的設計，在100萬赫茲的工作頻率下，我們的幅內模式選擇器使用了約28000個邏輯閘而幅間模式選擇器使用了約24000個邏輯閘。在25萬赫茲的工作頻率下，我們的幅內模式選擇器和幅間模式選擇器都能每秒壓縮30張解析度為720p HD (1280x720) 的影像畫面。我們並使用一個多媒體系統晶片平臺來將我們的模式選擇器整合到一個支援H.264先進影像壓縮技術主要規格的壓縮系統中。

We propose two efficient hardware architectures for inter and intra mode decision, respectively, in high resolution H.264/AVC encoding. Our approach delivers almost the same video quality as the H.264/AVC reference software does. Our inter mode decision architecture employs a novel resource sharing scheme to support multiple reference frames. Synthesized using a TSMC .13μm CMOS cell library, our inter mode decision unit and intra mode decision unit take 28k and 25k gates, respectively, for 100 MHz performance. Both units can encode 720p HD (1280x720) video at 30 frames per second when running at a 25-MHz FPGA platform. We have integrated the proposed mode decision units into an H.264/AVC main profile encoder system using a multimedia SOC platform.
