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.

The editor and debugger are integrated into a single application and provide a seamless embedded project development environment. Customers who purchased this product also bought:. List of all our Products. This greatly reduces the overall memory requirement of most applications.

D. Assembler Differences

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

The bank assembler process requires approximately 50 CPU cycles and consumes an additional 2 bytes of stack space. The A51 Assembler is a macro assembler for the family of microcontrollers. Another powerful feature of the A51 Assembler macro processors is conditional assembly depending on command line directives or assembler symbols.

By default, the following code sections are automatically located in the common area:.

It allows you to define and use macros in your assembly programs. All the above components also are included as part of the Compiler and Assembler package, as well as the Professional Developer’s Kit package.

It may also contain frequently used code. Software support for the external assemboer switching hardware includes a short assembly file you can edit for your specific hardware platform.

Since the does not directly support more than 64 Kbytes of code address space, there must be external hardware that swaps code banks. The register banks used, and the total number of warnings and errors are at the end of the listing file. MPL has several predefined macro processor functions that perform many useful operations like string manipulation or number processing.

Warning messages and error messages are listed at the end assembper the MAP file. The A51 assembler supports symbolic access to all features of the architecture.

Enter keywords to find the product you are looking for in the Quick Find field above or use Advanced Search. It supports all derivatives. The A51 assembler translates assembler source files into a relocatable object modules.

The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. The linker automatically selects the appropriate run-time library and links only those library modules that are required. The Standard Macro Processor is the easier macro processor to use. The hardware that does this assemble be controlled by software running on the It asssembler symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical.

The common area in a bank switching program is an area of memory that can be 3 accessed at all times from all banks. These object modules must adhere to the OMF51 object module specification. Write a review on this product! These directives are useful when using indirectly called functions or when disabling overlaying for debugging.


The overlay-map displays the structure of the program and the location of the bit assemvler data segments of each function.

This product was added to our catalog on Tuesday 18 February, Tell someone assekbler know about this product. Functions that are frequently invoked from multiple banks should be located in the common area. The standard macro syntax is compatible with that used in many other assemblers.

Getting Started and Creating Applications The linker resolves external and public references and assigns absolute or fixed addresses to relocatable program segments.

The common area contains program sections and constants that must be available at all times.

Assembling Programs specifies how to run the assembler and generate object files. This process is known as bank switching. Error Messages lists all error and warning messages that are generated by the assembler.
