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.

Listing File Following is an example listing file generated by the assembler. It generates a listing file optionally with symbol table and cross reference.

BL51 produces a MAP file extension. The linker resolves external and public references and assigns absolute or assemble addresses to relocatable program segments. It supports all derivatives.

The linker automatically selects the appropriate run-time library and links only those library modules that are required. It translates symbolic assembler language mnemonics into executable machine code. The A51 assembler translates assembler source files into a relocatable object modules. The overlay-map displays the structure of the program a511 the location of the bit and data segments of each function. Functions that are frequently invoked from multiple banks should be located in the common area.

Error messages and warning messages are included a5 the listing file. These directives are useful when using indirectly called functions or when disabling overlaying for debugging.

A D. Assembler Differences

It allows you to define and use macros in your assembly programs. The A51 assembler supports symbolic access to all features of the architecture. Tell someone you know about this product. When your C program calls a function located in a different bank, it switches the bank, jumps to the desired assember, restores the previous bank when the function completesand returns execution to the calling routine.

The memory map 3 contains the usage of the physical memory. The Appendix provides numerous details about the assembler including instruction set, limitations, reserved words, and predefined symbols. Map File Following is an example listing file generated by BL Customers who purchased assemboer product also bought:.

The A51 Assembler is a macro assembler for the family of microcontrollers. The common area contains program a5 and constants that must be available at all times.

The editor and debugger are integrated into a single application and provide a seamless embedded project development environment. Software support for the external bank switching hardware includes a short assembly file you can edit for your specific hardware platform. In addition to object files, the A51 assembler generates list files which optionally may include symbol table and cross reference information.


The A51 Assembler supports two different macro processors:. Since the does not directly support more than 64 Kbytes of code address space, there must be external hardware that swaps code banks.

A51 Macro Assembler

It is an endless. The A51 Assembler is a macro assembler for the microcontroller family. This greatly reduces the overall memory requirement of most applications. Getting Started and Creating Applications Another powerful feature of the A51 Assembler macro processors is conditional assembly depending on command line directives or assembler symbols.

Control Statements permit you to define symbol values, reserve and initialize storage, and control the placement of your code.

Assembler (Keil)

It supports all derivatives. The A51 Assembler translates an assembler source file into a relocatable object module. By carefully grouping functions in the different banks, you can create very large, w51 applications. It also allows you to generate different applications from one assembly source file. Assembling Programs specifies how to run the assembler and generate object files.
