CODAJ12
硬件JPEG编解码器核心

Chips&Media CODAJ系列是独立和高性能的JPEG编解码器IP,可以执行JPEG基线和MJPEG解码和编码。

完全符合ISO / IEC 10918-1 JPEG标准的基线和扩展顺序DCT模式,CODA-J系列内核还能够支持具有不同颜色格式的运动JPEG流,

支持高达32Kx32K的分辨率。 其完全基于硬件的架构可实现非常高的性能和低功耗,使其适用于各种数字成像应用。

 

动态前后图像处理还可以有助于提高存储器带宽效率。

CODAJ系列设计用于可靠性和易于集成,通过32位AMBA3 APB总线与系统连接,用于系统控制,并通过64位AMBA3 AXI总线进行数据吞吐.G24:G25
