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 sizeof is a unary operator in the programming languages C and C++. It generates the storage size of an expression or a data type, measured in the number of ''char''-sized units. Consequently, the construct ''sizeof (char)'' is guaranteed to be ...

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 CyberWorkBenc
