Value
Specifies which memory bank horizontal coefficient writes from the
Avalon-MM interface are made into.
Specifies which memory bank is used for horizontal coefficient reads
during data processing.
Specifies which memory bank vertical coefficient writes from the Avalon-
MM interface are made into.
Specifies which memory bank is used for vertical coefficient reads during
data processing
Specifies values for the horizontal coefficients at a particular phase. Write
these values first, then the Horizontal Phase to commit the write.
Specifies which phase the Horizontal Tap Data applies to. Writing to
this location, commits the writing of tap data. This write must be made
even if the phase value does not change between successive sets of tap
data.
Specifies values for the vertical coefficients at a particular phase. Write
these values first, then the Vertical Phase to commit the write.
Specifies which phase the Vertical Tap Data applies to. Writing to
this location, commits the writing of tap data. This write must be made
even if the phase value does not change between successive sets of tap
data.
