一种信号处理系统包括用于对存储在存储器中的多维信息阵列执行逻辑功能的装置。通常，存储器存储二维视频信息（像素），并且逻辑函数是离散余弦变换（DCT）或其它线性运算。对信息的行和列执行逻辑功能。在现有技术中，这需要两个存储器空间，使得信息可以被写入一个存储器，同时从另一个存储器读出。在本发明中，通过以指定的顺序对每个存储器位置执行读-修改-写操作，使用单个存储器空间来在行和列格式之间转置信息。
A signal processing system includes means for performing a logic function on a multi-dimensional array of information stored in a memory. Typically, the memory stores two-dimensional video information (pixels), and the logic function is a discrete cosine transform (DCT), or other linear operation. The logic function is performed on both rows and columns of the information. In the prior art, this has required two memory spaces, so that information could be written into one memory while being read out of another memory. In the present invention, a single memory space is used to transpose the information between row and column format, by performing a read-modify-write operation on each memory location in a specified sequence.
