Here are the data structures with brief descriptions:

XCresample	The XCresample driver instance data structure
XCresample_Config	This typedef contains configuration information for a Video device
XHorizontal_Coeffs	The XCoeffs is a structure contains predefined fixed coefficient values for Horizontal filter of two phases (phase 0 and phase 1)
XVertical_Coeffs	The XCoeffs is a structure contains predefined fixed coefficient values for Vertical filter of two phases (phase 0 and phase 1)
