When we implement the lookup table, we can use RTL or ROM. How to evaluate the cost between RTL and ROM? Thanks. May the small lookup table can be implement by RTL. The larger use ROM. What's the limit?
Thanks.
Thank you for your help.
I want to know whether I should connect output enable(active low) and chip enable(active low) always to the ground to let output not be high impedence.
Someone said it should be because high impedence will cause the circuit's power be very large.
Someone said that if...
As you known, the data output of memory maybe is the high impedance. When the high impedance is transferred to the following logic, can it result in high current? I’m not sure.
In general, how to avoid the high impedance to transfer? I mean, if the data output of memory is Z state ( The...
