4. bus throughput Consider a serial bus (1 bit wide) that runs at 2GHZ, usingalternate cycles for control signals and the other half of the cycles for data. What is the throughput of the busin bytes/second? Assume you wantto attach a video camera using this bus. The camera generates 60 frames per second, with each frame containing 1 Million pixels, each pixel 4 bytes in size. Would this work? Answer one of the below: a) If not, what compression factor would the camera need to achieve to be supported? A compression factor describes how mu ch smaller the data is when compared to un- compressed data. b) If yes, how many cameras could be connected?
