ating system consistency are automatically controlled by the BL51 linker/locator. C51 Optimizing C Cross Compiler The Keil C51 Cross Compiler is an ANSI C Compiler that was written specifically to generate fast, pact code for the 8051 microcontroller family. The C51 Compiler generates object code that matches the efficiency and speed of assembly programming. Using a highlevel language like C has many advantages over assembly language programming: Knowledge of the processor instruction set is not required. Rudimentary knowledge of the memory structure of the 8051 CPU is desirable (but not necessary). Details like register allocation and addressing of the various memory types and data types is managed by the piler. Programs get a formal structure (which is imposed by the C programming language) and can be divided into separate functions. This contributes to source code reusability as well as better overall application structure. The ability to bine variable selection with specific operations improves program readability. Keywords and operational functions that more nearly resemble the human thought process may be used. Programming and program test time is drastically reduced. The C runtime library contains many standard routines such as: formatted output, numeric conversions, and floatingpoint arithmetic. Existing program parts can be more easily included into new programs because of modular program construction techniques. The language C is a very portable language (based on the ANSI standard) that enjoys wide popular support and is easily obtained for most systems. Existing program investments can be quickly adapted to other processors as needed. Code Optimizations The C51 Compiler is an aggressive optimizing piler that takes numerous steps to ensure that the code generated and output to the object file is the most efficient (smallest and/or fastest) code possible. The piler analyzes the generated code to produce the most efficient instruction sequences. This ensures that your C program runs as quickly and effectively as possible in the least amount of code space. The C51 Compiler provides nine different。
