Hello all, I am in the process of selecting a processor. I have few queries related with the selection of a processor for embedded systems design . For selecting the correct processor to handle high rate of data, is there any mapping/logic between the processor clock speed and the rate in which the data enters the processor . That is, consider that the data comes in at the rate of 1Gbps in the input port of the processor. What is the possible clock rate that the processor should operate/support to handle the data ? If there is an external memory/ RAM requirement, how much memory should be there for that particular processor clock frequency for that particular speed(1Gbps) of input data and what is the logic to determine that ? How does the number of bits of processor play a role in the selecting a processor to support high speed data(1Gbps) ? Does internal memory/cache also have any role in taking the decision . If Yes, how to determine the amount of such memory for this high speed data(1Gbps) ? Are there other factors ? In general, i need the a table of these factors mapped against various other factors or the clear method/logic of determining it so that it can be considered to select a processor for processing high speed data.
