Microtec has released a software tool to aidin programming the Intel 8051 micropro-cessor. The relocatable macro assembler andlinking loader programs are written in ANSIstandard Fortran IV and consequently will runon any general-purpose computer with a wordlength of at least 16 bits.

The assembler is compatible with Intel in-struction mnemonics and largely compatiblewith the directives (pseudo-ops) used by Intel'sassembler. Features include conditional as-sembly, the ability to produce a symbol orcross-reference table, and a macro facility thatallows the passing of expressions, constants,labels, and complete instructions as param-eters. Macros may be nested to any level, maybe recursive, and may utilize local symbolsknown only to an expanded macro.

The 8051 assembler is a two-pass programthat issues error messages and produces a pro-gram listing. Symbolic and relative address-ing, forward references, complex expressionevaluation, cross-reference listing, and a set ofdirectives are also featured. The assembler iscapable of generating data in several number-based systems as well as both ASCII and EBC-DIC character codes.

The linking loader combines several inde-pendently assembled relocatable object mod-ules into a single absolute program. Large pro-grams can be subdivided into smaller units toreduce assembly time. A load map displayingthe name of each object module and each sec-tion and their starting addresses is included inthe output of the loader. The absolute objectmodule output of the loader is in Intel's stan-dard ASCII hexadecimal format and may in-clude a symbol table.

Method protects againstsoftware piracy

Advanced Computer Security Concepts isoffering a procedure designed to prevent soft-ware piracy. The approach is based on a pat-ented method of using the US government-ap-proved data encryption standard. Accordingto the company, it is user transparent, protectsthe master key, and validates software at initi-ation and also dynamically during operation.The method can bind a software package to

a specific hardware device, to a specific user onany hardware device, or to a specific user on a

specific hardware device, the company stated.It is also adaptable to preventing unauthorizeduse of a software package installed on a time-shared system.

Using the method requires either a softwareor a hardware DES implementation. Oneboard or module can be used to validate allsoftware packages that are executed on a de-vice, provided the software package has beensuitably protected. The protection consists ofperiodically authenticating cryptographicallygenerated validation values that an intrudercannot determine.The cost for implementing this approach

varies with the hardware, software, and usage.

There is an incremental cost for protecting anycopy of a software package after the DES is in-stalled in the hardware.

Tracmacs is designed to help system design-ers and programmers audit the quality andcompleteness of software testing and test datato assure that a program has been thoroughlytested. It is a logic path analyzer that shows atthe condition statement level which paths haveyet to be tested, which decision paths were ex-ecuted (IF-THEN-ELSE) and in what se-quence, and the number of times the true orfalse branches were executed. The result is anaudit of each program execution at the condi-tional level.

Tracmacs is available for any computer witha Cobol compiler. It sells for $12,000.
