Embodiments of the present invention provide for improved timing control in 2-D image processing to maintain a constant rate of memory fetches and pixel outputs even when the processing operations transition to a new line or frame of pixels. A one-to-one relationship between incoming pixel rate and outgoing pixel rate is maintained without additional clock cycles or memory bandwidth as an improved timing control according to the present invention takes advantage of idle memory bandwidth by pre-fetching a new column of pixel data in a first pixel block of a next line or frame while a new column of an edge pixel block on a current line is duplicated or zeroed out. As the edge pixel block(s) on the current line are processed, the data in the first pixel block of the next line or frame become ready for computation without extra clock cycles or extra memory bandwidth.

Methods and apparatus for image processing at pixel rate

A Peripheral Component Interconnect (PCI) Express switch is provided. The PCI Express switch includes a first routing information bus connected to the first port; a second routing information bus connected to the second port; a third routing information bus connected to the third port; two routing slaves in the first port, each dedicated to listening to one of the second and the third routing information buses; two routing slaves in the second port, each dedicated to listening to one of the first and the third routing information buses; and two routing slaves in the third port, each dedicated to listening to one of the first and the second routing information buses.
