为了满足嵌入式领域需求,针对无限冲激响应(IIR)高斯滤波器,提出了一种定点化策略,能够有效地替代浮点数实现版本.为了进一步提高滤波速度,设计了一款传输触发架构(TTA)处理器,并针对该算法特点,定制特殊功能单元,优化存储结构.实验结果表明,对于大小为640×480的24位真彩图像,IIR型高斯滤波的TTA实现速度是通用DSP的4.12倍.
In order to meet the needs of the embedded field
a fixed-point strategy is proposed for the infinite impulse response Gaussian filter
which can effectively replace the floating-point implementation version. In order to further improve the speed of filtering
a Transport Triggered Architecture processor is designed
and special function units are customized for the characteristics of the algorithm
and the storage structure is optimized. The experimental results show that for a 24-bit true color image with a size of 640×480
the Transport Triggered Architecture implementation speed of the IIR Gaussian filter is 4.12 times that of the general-purpose DSP.
