SystemC vs. TLA+ vs. Unlambda vs. jscoverage Comparison Chart

Your online reference for everything related to SystemC, the language for system-level design, high-level synthesis, modeling and verification. SystemC™ addresses the need for a system design and verification language that spans hardware and software. It is a language built in standard C++ by extending the language with the use of class libraries. The language is particularly suited to model system's partitioning, to evaluate and verify the assignment of blocks to either hardware or software implementations, and to architect and measure the interactions between and among functional blocks. Leading companies in the intellectual property (IP), electronic design automation (EDA), semiconductor, electronic systems, and embedded software industries currently use SystemC for architectural exploration, to deliver high-performance hardware blocks at various levels of abstraction and to develop virtual platforms for hardware/software co-design.

Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.
