    Design a simple serial-to-parallel data converter. The circuit reads data serially, adds a parity bit to it and then output it in parallel (8-bits) along with a strobe signal. The data format is as follows; 2 start bits (two 1s), a single stop bit (0) and the data packets (each is 7-bits long) are separated by a single 1 (continuation bit). When there is no data on the input it is kept low (i.e. 0). The circuit should be fully synchronous with an external clock and have a master asynchronous reset input. The diagram below shows the block diagram of the circuit and the data format.

    Hints or Help

    thanx alot in advance

    Just about any old body's RS-232 ic does these things. Look for RS-232 ic's on google. Maxim is one mfr - you should be able to find internal block diagrams at least.
