MacroExpressions

Based on their software development experience in embedded applications, MacroExpressions have identified several pieces missing from the common software development toolchains. The missing pieces have to do with code reuse and maintainability of software projects. MacroExpressions products, Unimal and C-SLang, supplement other tools by patching those omissions. Their products are complemented by their services. They include applications and/or customizing of the products.

MacroExpressions helps the following:

  • Embedded systems developers and project managers facing maintainability problems in "same-but-different" model-year or product line environment can put Unimal to good use.
  • Engineers who design embedded devices and systems with testability in mind will benefit from using C-SLang.
  • Embedded devices manufacturing and quality control personnel in particular will appreciate working with C-SLang-enabled devices.
  • Developers concerned with saving precious memory resources will benefit from C-SLang and Unimal.
  • Vendors and integrators of embedded development tools may find it advantageous to include Unimal and C-SLang as parts of their toolchains.

C-SLang is a novel embedded diagnostic tool. It is method of turning an ISO/ANSI C compiler into a generator of very compact Assembler-like scripts, with the size of the virtual machine of about 2K (depending on the platform). It is useful for test and diagnostic procedures, such as in embedded devices manufacturing, end-of-line and field return testing and similar tasks.

UNIfied MAcro Language (Unimal) adds new features to high-level languages in a way independent of the target language. It reduces project maintenance complexity and data footprint by:

  • very sophisticated compile-time initialization
  • sharing parameters across languages
  • multiple-file output, and more

Unimal supplements HLLs with:

  • capabilities of early evaluation of constant numerical expressions
  • freely definable calculated names
  • capabilities of repeated scanning of a segment of the source code
