Figure 2-21. Input DDR/Shift Register Block
Output Register Block
The output register block provides the ability to register signals from the core of the device before they are passed
to the PURESPEED I/O buffers. The block contains a register for SDR operation and a group of registers for DDR
and shift register operation. The output signal (DO) can be derived directly from one of the inputs (bypass mode),
the SDR register or the DDR/shift register block. Figure 2-22 shows the diagram of the Output Register Block.
Output SDR Register/Latch Block
The SDR register operates on the positive edge of the high-speed clock. It has clock enable that is driven by the
clock enable output signal generated by the control MUX. In addition it has a variety of programmable options for
set/reset including, set or reset, asynchronous or synchronous Local Set Reset LSR (LSR has precedence over
CE) and Global Set Reset GSR enable or disable. The register LSR input is driven from LSRO, which is generated
from the PIO control MUX. The GSR inputs is driven from the GSR output of the PIO control MUX, which allows the
global set-reset to be disabled on a PIO basis.
Output DDR/Shift Block
The DDR/Shift block contains registers and associated logic that support DDR and shift register functions using the
high-speed clock and the associated transfer from the low-speed clock domain. It functions as a gearbox allowing
low-speed parallel data from the FPGA fabric be output as a higher speed serial stream. Each PIO supports DDR
and x2 shift functions. If desired PIOs A and B or C and D can be combined to form x4 shift functions. Figure 2-22
shows a simplified block diagram of the shift register block.
