Keil's 8051 Assembler for PC-hosted Systems
The A51 Assembler Kit for the 8051 microcontroller family enables you to write assembler programs for practically any 8051 derivatives including those from companies like Analog Devices, Atmel, Cypress Semiconductor, Dallas Semiconductor, Goal, Hynix, Infineon, Intel, OKI, Philips, Silicon Labs, SMSC, STMicroelectronics, Synopsis, TDK, Temic, Texas Instruments, and Winbond. The following components are included in the A51 8051 Assembler Kit:
A51 Macro Assembler
The A51 Assembler is a macro assembler for the 8051 family of microcontrollers. It supports all 8051 derivatives. It translates symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical. The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. The A51 assembler supports symbolic access to all features of the 8051 architecture.
The A51 assembler translates assembler source files into a relocatable object modules. The DEBUG control adds full symbolic information to the object module and supports debugging with the ÁVision3 Debugger or an in-circuit emulator. In addition to object files, the A51 assembler generates list files which optionally may include symbol table and cross reference information.
The ÁVision3 IDE from Keil Software combines project management, make facilities, source code editing, program debugging, and complete simulation in one powerful environment. ÁVision3 helps you get programs working faster than ever while providing an easy-to-use development platform. The editor and debugger are integrated into a single application and provide a seamless embedded project development environment. ÁVision3 features include:
- The Device Database which automatically sets the assembler, compiler, and linker options for the chip you select. This prevents you from wasting your time configuring the tools and helps you get started writing code faster.
- A robust Project Manager which lets you create several different configurations of your target from a single project file. The Keil ÁVision3 IDE allows you to create an output file for simulating, an output file for debugging with an emulator, and an output file for programming an EPROM -- all from the same Project file.
- An integrated Make facility with automatic dependency generation. You don't have to figure out which header files and include files are used by which source files. The Keil compilers and assemblers do that automatically.
- Interactive Error Correction. As your project compiles, errors and warnings appear in an output window. You may make corrections to the files in your project while ÁVision3 continues to compile in the background. Line numbers associated with each error or warning are automatically resynchronized when you make changes to the source.
BL51 Code Banking Linker/Locator
The BL51 code banking linker/locator combines OMF51 object modules and creates executable 8051 programs. The linker resolves external and public references and assigns absolute or fixed addresses to relocatable program segments.
The BL51 Linker processes object files created by the Keil C51 Compiler and A51 Assembler and the Intel PL/M-51 Compiler and ASM-51 Assembler. These object modules must adhere to the OMF51 object module specification. BL51 outputs an absolute OMF51 object module that may be loaded into practically any emulator, the Keil ÁVision3 Debugger, or the OH51 Object-HEX converter (to create an Intel HEX file).
OH51 Object-HEX Converter
The OH51 Object-HEX converter creates Intel HEX files from absolute OMF51 object modules, created by the Keil A51 assembler, BL51 code banking linker, or OC51 banked object converter.
Intel HEX files are ASCII files that contain a hexadecimal representation of your program. They easily may be loaded into a device programmer for writing EPROMs or other memory devices.
All the above components also are included as part of the 8051 Compiler and Assembler package, as well as the 8051 Professional Developer's Kit package.
