BXC 51

BASIC Compiler for the 8051/8052 family

Introduction

• BXC51 is a compiler for a BASIC language which is a fully compatible superset of the BASIC interpreter found in Intel's 8052AH-BASIC CPU. BXC51 was introduced in the spring of 1989 and has had two major upgrades since then.
• Prior to the introduction of BXC51, system designers had to resort to costly and time-consuming alternatives: they were confronted with assembly language, 'C', and/or PLM-51 when their systems outgrew the BASIC-52 interpreter. The release of Binary Technology, Inc.'s BXC51 compiler has changed this situation dramatically.

Save Time and Money

• Your program can now run up to 50 times faster and you can save over 80% on the cost of your CPUs by using the 8031 in place of the 8052AH-BASIC chip (based on Intel's list prices as of 10/3/91).

BASIC-52 Programs

• Start by writing your own program with a non-formatting test editor or by capturing an existing program from the 8052 BASIC CPU. In one step, use BXC51 to compile the program; no linking required. Download the resulting hex file into a programmer, plug the programmed PROM into your target system and you're done!

In-Line Assembly

• The BXC51 supports in-line assembly code eliminating the need for the complicated assembly interfacing required by the Intel BASIC-52 interpreter. With BXC51, just include an Sasm command, insert your lines of assembly code, and return to BASIC using the Sbasic command.

Hidden Source Code

• The source of your painstakingly developed program is now protected from being listed or otherwise divulged to non-authorized users.

BASIC-52 Standard

• BXC51 is the only compiler that fully adheres to Intel's BASIC-52 language standard. It includes all statements, expressions, string operators, extensions, interrupt handlers, real-time clocks, etc.

More Than Just BASIC-52

• Integer, bit, and byte variables for code that runs upto 50 times faster than the interpreter.
• The TRACE1 and TRACE0 statements allow line number tracking to aid in program debugging.
• The DEFASM statement extends the BASIC language by associating keywords with your assembly routines.
• The DEFVAR statement allows the programmer to specify the memory address of floating point, integer, and byte variables and arrays.
• The DEFCTRL statement allows the programmer to specify CPU control registers in byte variable form providing compatibility with all the new 8051 variants.
• Optimization of integer expressions to produce faster, smaller code.
• Exact error reporting and clear error messages.
• The -m command line option creates a detailed variable memory map in MAP file.
• The -c command line option allows the user console I/O and stray interrupt vectors located at 4000H to be located elsewhere or be totally ignored.
• The -a command line option passes the -I command line option to SXA51 (cross assembler) to produce a long assembly listing.

Built-In Cross-Assembler

• Included with the BXC51 is Binary Technology, Inc.'s SXA51 cross-assembler HEX file manipulation utility plus full documentation and sample programs.
