Bitslip logic
WebThe optional rx_bitslip_ctrl signal controls the bit insertion of each receiver that is independently controlled from the internal logic. The data slips one bit on the rising edge of rx_bitslip_ctrl. The rx_bitslip_ctrl signal has the following requirements: The minimum pulse width is one period of the parallel clock in the logic array. WebApr 12, 2024 · A block diagram is shown in Figure 6 and it consists of the deserializer followed by the bitslip detection and correction blocks. The deserializer module expects DDR (double data rate) data and has a deserialization factor of 1:8. ... the SDF-FFT control logic forces data flushing that can significantly reduce the total latency. During the ...

WebApr 29, 2014 · I want to implement a generic bitslip module. Below is an example of what I want to do for 4 and 8. I cannot figure out how to write code so I can pass some generic N and the code will be generated automatically using for loops or something. ---- 4-bitslip bits_slipped <= bits_in (3 downto 0) when tap_sel = "00" else bits_in (2 downto 0) & bits ... In digital transmission, bit slip is the loss or gain of a bit or bits, caused by clock drift – variations in the respective clock rates of the transmitting and receiving devices. One cause of bit slippage is overflow of a receive buffer that occurs when the transmitter's clock rate exceeds that of the receiver. This causes one or more bits to be dropped for lack of storage capacity.
WebReceiver Settings Tab—Bitslip Settings. Turn on to add a bit slip block to the receiver data path and expose the rx_bitslip_ctrl port (one input per channel). Every assertion of the rx_bitslip_ctrl signal adds one bit of serial latency to the data path of the specified channel. Turn on to expose the rx_bitslip_reset port (one input per ... WebThe rx_bitslip_ctrl signal has the following requirements: The minimum pulse width is one period of the parallel clock in the logic array. The minimum low time between pulses is one period of the parallel clock. The signal is an edge-triggered signal. The valid data is available four parallel clock cycles after the rising edge of rx_bitslip_ctrl.

WebUsing BITSLIP allows for word framing by providing a control signal generated in the FPGA fabric and by parallel word logic running at parallel word clock rates. The Lx_BIT_SLIP input control is synchronized to the HS_IO_CLK clock allowing word framing by suppressing one HS_IO_CLK pulse. ... Assertion of the Lx_BITSLIP control signal allows the ...
