Hey guys,
I am confused on how to approach this problem, and was hoping you guys could help. The problem is:
An 8‐bit parallel bus that has a peak transfer rate of 10 Kbytes/second is to be replaced with a serial link providing the same capacity. The link will be formed by connecting UARTs on each side with a serial cable. Each byte will be transmitted on the serial link as 8 data bits + 1 start bit + 1 stop bit + odd parity.
A). What is the minimum frequency required of the serial clock?
B). Show the serial clock and data waveforms during the transfer of the byte 11011001 on the link. Assume that the byte is transmitted such that the rightmost bit is transmitted first on the wire.
C). Calculate the baud rate on the link.
This looks like an 8b10b encoding. I'm not too sure what the minimum frequency would be. Would this be related to the transfer rate? My notes aren't too helpful as the professor leaves us with a cliff hanger of sorts. Any help on all three questions would be appreciated. Thank you.
