Q: You have 8 bit ADC clocking data out every 1mS. Design a system that will sort the output data and keep a statistics how often each binary number appears at the output of ADC. 
The diagram showes a basic idea of a possible solution: using RAM to store a statistic data. The digital number that is to be stored is considered as a RAM address. Once digital data at the output of ADC becomes available, memory controller generates RD signal, and the contence of the memory cell addressed by ADC output latches into D register. "1" in the D-register enables WR signal to the next memory cell. To calculate how many times a certain number appeared at the output of ADC it necessary to summarize the contence of all memory cells. |
