Scrolling dynamically updated bitmap?

I'm new to DirectX but I need to display the following:

I am receiving blocks of 256 bytes of data at about 15 times a second. I need to add each block as a line of 256 pixels (with the byte value determining the colour of the pixel) to the right side of a bitmap. When the width of the bitmap extends past the width of the viewing area, I need to scroll the bitmap one pixel to the left (drop the left-most column of pixels to make room for the new column on the right).

The question is, how can I do this efficiently? Is it possible to create a circular buffer type-of-thing directly on the graphics/video memory? Any pointers towards a suitable solution or examples would be much appreciated.
