Abstract :
The authors describe extensions to the ELLA system for specifying hardware circuits containing mixed behavioural and structural real arithmetic, from the highest abstract level down to bit level. A consequence of these extensions is the provision of an extensive set of logical and arithmetic operators on arbitrary length arrays of bits in both signed and unsigned format. The authors outlines the rationale used in the development and shows how the extensions can be used to access the host´s own operators
