Hello All,
I am using C51 and my code runs on Infineon controller.
For company policy reason I am not revealing the exact controller and sorry
about that.
I would like to improve the speed. I was using the large memory model for
this compiler
and now I use small memory model. This has improved speed a lot.
I would like to know if there are some more such settings for this compiler
to improve the speed.
Thank you in advance.
# Read the assembler output, and start to learn the code the compiler
creates for given constructs. ie understand your tools
# Focus on the code blocks, where you know speed matters.
# Use in-line assembler, but only as a last resort.
# Increase the CPU clock speed, or move to a newer infineon model, like
the 868 or 888 variants ?
