The data rate should be quite a factor less than clock frequency so as to obtain correct output waveforms. Serial to Parallel Convertor Abstract - In the actual scenario of communication, present day chips have parallel data bus but for long distance communication laying down parallel channels for every bit is costly and hardware consuming.
But transmitting data in this format is not feasible in terms of hardware and cost productivity. Features The converters can be a N-bit, implying the output can be obtained in N-bit parallel data.

We will see how to implement the VHDL code for a serial to parallel interface in order to get back the parallel data bus we sent in the transmitter device. Let assume the parallel data bus of the Serial to Parallel converter to be N bit. The parallel output to the module will be available every N clock cycle since N clock cycles are needed to load the shift register that provided the parallel output as in Figure2.
With respect to the parallel to serial converter in this case no error detection logic is present. The output parallel data rate is slower than the input serial data rate, so no error condition can occur. In the simulation of all the figures below, the clock is set to 10 ns, so 80 ns mean 8 clock cycles. In order to realize the test bench, the parallel to serial converter of this post is used.
As a convention , the first serial output bit is the MSB of the input parallel data. You can choose to output first the LSB. It depends on the convention you are using. As clear the serial input to be parallelized is re-serialized in the byte signal. In this post, we implemented a simple example of a serial to parallel VHDL code.
