Hardware Description Language for Optical Processing Current version of HADLOP: 2.3.0

What is HADLOP ?

HADLOP is a simulation system for parallel digital optoelectronic and optical architectures. It was designed in order to verify the logical behavior of algorithms working on 2-dimensional data planes. These planes are manipulated by optical or optoelectronic devices which are connected optically (e.g. Smart Pixel- and SEED-Systems).

How does HADLOP work ?

Optical and optoelectronic devices are represented by so called architecture primitives. HADLOP provides a versatile set of efficient primitives making it possible to emulate all kind of real existing devices. Some freely programmable primitives allow to specify their logical behavior on a quite abstract level - similar to programming languages. Therefore the simulation system has also become suitable for simulations of general parallel computer systems.
All architecture primitives can be handled very easily using 'Drag & Drop' functions with the mouse.

News & Infos

February 3, 1998 - We have removed a bug from the SUN version of HADLOP 2.3.0. This bug affected the C++ primitive.
Download a new 2.3.0 binary for SUN workstations, please.

The new C/C++ primitive - not documented in the HADLOP Manual 1.0 yet.
