he drew a diagram on the white board, asked me this synchronization problem abt 2 processes trying to communicate with the hardware. there was 1 bit register on the hardware u can use as extra memory if u want. there were several approaches i tried, some which wouldnt work, the rest im not sure if they were right. in the end he said now give me a solution if it were a multi processor system. i didnt really say much after that. was pretty stuck.
