Hi,
I'm currently using 8-bit 8051 serial MCU which will utilize the external memory model, whereas i still desire to reduce the external memory accesses as much as possible!

The Compiler is Keil!

Shall i adopt the SMALL memory model or the LARGE memory model?

Thanks in advance!

Thomson,
that depends. Using the small memory model will keep you code smaller and even faster but you will have to do some "tricks" for long branches. Most important is how much time do you want to invest to keep the code let's say 5% smaller and 5% faster?
If time to market is important and you want to make it simpler for you, I would recommend to use the large memory model.
