Behavioral Description Language (BDL) is a programming language based on ANSI C with extensions for hardware description, developed to describe hardware at levels ranging from the algorithm level to the functional level. Although the term behavioral description language is a generic term and can refer to multiple high level description languages, NEC Corporation has developed a C-subset called BDL for High Level Synthesis. This C-subset includes its own data types (called var-class), special constants for hardware design e.g. high impedance, timing descriptors and control statements. As BDL is meant for Hardware synthesis, the complete ANSI-C syntax is not supported. The principal unsupported operations are: (i) Floating point data types (ii) Sizeof operator (iii) unions and (iv) Recursive functions. BDL is sometimes also known as Cyber C because it is synthesized using NEC's High Level Synthesis tool called CyberWorkBench (). ==References== K. Wakabayashi and T. Okamoto. 2006.
