簡介AM8268N是Actions炬力推出的一款高度集成的混合信號SoC多媒體應用處理器芯片
AM8268N是Actions炬力推出的一款高度集成的混合信號SoC多媒體應用處理器芯片。AM8268N內置的CPU是一個高性能、低功耗的32位RISC內核，具有DSP指令擴展，運行速度可達800MHz。
AM8268N處理器采用硬聯(lián)線多格式視頻，支持各種主流視頻格式，包括：H.264、RMVB、MPEG1/2/4和VC1。AM8268N集成圖像/視頻處理器和顯示引擎，可提供強大的圖像處理能力，如無縫放大/縮小、裁剪、旋轉、顏色空間轉換、伽瑪校正、邊緣增強、抖動、亮度、對比度和飽和度調整。此外，為其他擴展保留了一個可配置的FIR。兩層OSD窗口可以配置為全屏大小，顏色深度從1位到32位真彩色。
AM8268N多媒體處理器支持HDMI輸出，可提供優(yōu)質的顯示解決方案，它集成了一個512Mb DDR2 SDRAM控制器、1個USB OTG控制器、UART、I2C、SPI等接口，是一顆性價比的圖像處理Soc單芯片。
