Abstract

If you've flicked through this publication, you may be left thinking that it is necessary to be an expert to produce workable programs with C51. Nothing could be further from the truth. It is perfectly possible to write real commercial programs with nothing more than a reasonable knowledge of the ANSI C language.

However, to get the maximum performance from the 8051, knowing a few tricks is very useful. This is particularly true if you are working on a very cost-sensitive project where needing a bigger RAM or EPROM can result in an unacceptable on-cost. After all, if cost was not a consideration, we would all be using 80C166s and 68000s!

Whilst the C51 Primer is really aimed at users of the Keil C51 Compiler, it is applicable in part to compilers such as IAR and Tasking. However, as these compilers do not allow such low-level access and have fewer 8051-specific extensions, they are le ss likely to be used on projects where getting maximum performance is essential.

The C51 Primer Will Help You:

• Find your way around the basic 8051 architecture.
• Make a sensible choice of memory model and special things to watch out for.
• Locate things at specific addresses.
• Make best use of structures.
• Use bit-addressable memory.
• Think in terms of chars rather than ints.
• Get the best out of the various pointer types.
• Get a modular structure into programs.
• Access on and off-chip ports and peripherals.
• Deal with interrupts.
• Use registerbanks.
• Deal with the stack.
• Understand RAM overlaying.
• Interface to assembler code.
• Use special versions like the 80C517 and 87C751.
• Use assembler tricks in C.
• Help the optimiser to produce the smallest, fastest code.
