A51 ASSEMBLER PDF
A51 – Assembler Kit The A51 Assembler Kit for the microcontroller family enables you to write assembler programs for practically any derivatives. This Assembler User’s Guide provides an overview of the Keil A51 and AX51 Assemblers. It contains the following chapters. Introduction provides a brief. The CA51 Compiler Kit for the microcontroller family supports all derivatives including classic devices and IP cores from companies like Analog.

D. Assembler Differences
Functions that are frequently invoked from multiple banks should be located in the common area. The overlay-map displays the structure of the program and the location of the bit and data segments of each function. However, it is easy for you to specify custom settings for your application. List of all our Products.
The A51 Assembler is a macro assembler for the family of microcontrollers. Software support for the external bank switching hardware includes a short assembly file you can edit for your specific hardware platform. The A51 Assembler is a macro assembler for the microcontroller family. Notify me of updates to Assembler Keil. The common area contains program sections and constants that must be available at all times.
It is an endless.
A51 Macro Assembler
Control Statements permit you to define symbol values, reserve and initialize storage, and control the placement of your code. This chapter discusses the directives that are available.
The A51 assembler translates assembler source files into a relocatable object modules. Another powerful feature of the A51 Assembler macro processors is conditional assembly depending on command line directives or assembler symbols.
A51 produces a listing file with line numbers as well as the time assmbler date of the translation. The Standard Macro Processor is the easier macro processor to use.
Keil A51 Macro Assembler
It supports all derivatives. The hardware that does this must be controlled by software running on the The linker resolves external and public references and assigns absolute addresses to relocatable programs segments. The editor and debugger are integrated into a single application and provide a seamless embedded project development environment.
This allows exact display of program. Since the does not directly support more than 64 Kbytes of code address space, there must be external hardware that swaps code banks. BL51 displays the invocation line and the memory model.
BL51 produces a MAP file extension. Map File Following is an example listing file generated by BL By default, the following code sections are automatically located in the common area:. Error Messages lists all error and warning messages that are generated by the assembler. This product was added to our catalog on Tuesday 18 February, Information about assembler invocation and the object file generated is printed. The linker resolves external and public references and assigns absolute or fixed addresses to relocatable program segments.
It contains the following chapters. The Appendix provides numerous details about the assembler including instruction set, limitations, reserved words, and predefined symbols.
The A51 assembler supports assemhler access to all features of the architecture. The register banks used, and the total number of warnings and errors are at the end of the listing file.
You can dramatically improve system performance by grouping interdependent functions in the same bank. When your C program calls a function located in a different bank, it switches the bank, jumps to the desired function, restores the previous bank when the function completesand returns execution to the calling routine.
The A51 aswembler supports symbolic access to all features of the architecture.
By carefully grouping functions in the different banks, you can create very large, efficient applications. The A51 assembler translates assembler source files into a relocatable object modules.
