Add util_upack2 core The util_upack2 core is similar to the util_upack core. It unpacks, or deinterleaves, a data stream onto multiple ports. The upack2 core uses a streaming AXI interface for its data source instead of a FIFO interface like the upack core uses. On the output side the upack2 core uses a multi-port FIFO interface. There is a single data request signal (fifo_rd_en) for all ports. But each port can be individually enabled or disabled using the enable signals. This modified architecture allows the upack2 core to better generate the valid and underflow control signals to indicate whether data is available in a response to a data request. If fifo_rd_en is asserted and data is available the fifo_rd_valid signal are asserted in the following clock cycle. The enabled fifo_rd_data ports will be contain valid data during the same clock cycle as fifo_rd_valid is asserted. During other clock cycles the output data is undefined. On disabled ports the data is always undefined. If no data is available instead the fifo_rd_underflow signal is asserted in the following clock cycle and the output of all fifo_rd_data ports is undefined. This core is build using the common pack infrastructure. The core that is specific to the upack2 core is mainly only responsible for generating the control signals for the external interfaces. The core is accompanied by a test bench that verifies correct behavior for all possible combinations of enable masks. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

Add util_upack2 core The util_upack2 core is similar to the util_upack core. It unpacks, or deinterleaves, a data stream onto multiple ports. The upack2 core uses a streaming AXI interface for its data source instead of a FIFO interface like the upack core uses. On the output side the upack2 core uses a multi-port FIFO interface. There is a single data request signal (fifo_rd_en) for all ports. But each port can be individually enabled or disabled using the enable signals. This modified architecture allows the upack2 core to better generate the valid and underflow control signals to indicate whether data is available in a response to a data request. If fifo_rd_en is asserted and data is available the fifo_rd_valid signal are asserted in the following clock cycle. The enabled fifo_rd_data ports will be contain valid data during the same clock cycle as fifo_rd_valid is asserted. During other clock cycles the output data is undefined. On disabled ports the data is always undefined. If no data is available instead the fifo_rd_underflow signal is asserted in the following clock cycle and the output of all fifo_rd_data ports is undefined. This core is build using the common pack infrastructure. The core that is specific to the upack2 core is mainly only responsible for generating the control signals for the external interfaces. The core is accompanied by a test bench that verifies correct behavior for all possible combinations of enable masks. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
