The Standard Macro Processor is the easier macro processor to use. Each input module and the library modules included in the application are listed. It translates symbolic assembler language mnemonics into executable machine code. The bank switching process requires approximately 50 CPU cycles and consumes an additional 2 bytes of stack space. A51 produces a listing file with line numbers as well as the time and date of the translation.

A51 macro assembler A51 Assembler generates complete w51 number, symbol, and type. However, it is easy for you to specify custom settings for your application.

The Standard Macro Processor is the easier macro processor to use. The position of each error is clearly marked. The common area cannot be physically. Getting Started and Creating Applications By default, the following code sections are automatically located in the common area:.

A51 Macro Assembler

The linker automatically selects the appropriate run-time library and links only those library modules that are required. The A51 assembler supports symbolic access to all features of the architecture. Another powerful feature of the A51 Assembler macro processors is conditional assembly depending on command mscro directives or assembler symbols.


A51 produces a listing file with line numbers as well as the time and date of the translation. The common area in a bank switching program is an area of memory that can be 3 accessed at all times from all banks. In addition to object files, the A51 assembler generates list files which maro optionally include symbol table and cross reference information. These directives are useful when using indirectly a51 macro assembler functions or when disabling overlaying for debugging.

A Between A51 and ASM51

BL51 displays the invocation line and the memory model. Functions that are frequently invoked from multiple banks should be located in the common area. MPL has several predefined macro processor functions that perform many useful operations like string manipulation or number processing. It may also contain frequently used code. This allows exact display of program. It also allows you to generate different applications from one assembly source file.

Software support for the external bank switching hardware includes a short assembly file you can edit for a51 macro assembler specific hardware platform.

The A51 assembler translates assembler source files into a relocatable object modules. By continuing to use our site, you consent to our cookies. Warning messages and error messages are listed at the assemmbler of the MAP file.


Products Download Events Support Videos. It generates a assebler file optionally with symbol table and cross reference. The a51 macro assembler resolves external and public references and assigns absolute addresses to relocatable programs segments. Listing File Following is an example listing file generated by the assembler.

The register banks used, s51 the total number a51 macro assembler warnings and errors are at the end of the listing file. The overlay-map displays the structure of the program and the location of the bit and data segments of each function. The standard macro syntax is compatible with that used in many other assemblers. The memory map 3 contains the usage of the physical memory. This process is known as bank switching. It is an endless. Map File Following is an example listing file generated by BL
