The
basic SelectLink architecture is specified with three positive integers. They
are defined as follows: SLintWidth - The width in bits of the
internal User Data FIFO Buses in the Transmitter and Receiver. SLextWidth
- The width in bits of the external Double Data Rate bus (SL).
NumBlks - Number of SelectRAM+ blocks used in each FIFO (Transmitter
& Receiver) These three parameters are interdependent, and must satisfy
these two rules: SLintWidth/NumBlks = 1, 2, 4, 8, or 16
(2 x SLextWidth)/NumBlks = 1, 2, 4, 8, or 16 The values
of the parameters must fall within the indicated ranges. |
