(DDC-I would go on to stay in business longer than any of these others. ĭDC-I was in the same market as several other Ada compiler firms, including Alsys, TeleSoft, Verdix, Tartan Laboratories, and TLD Systems. This was even more so in the case of companies retargeting the compiler, many of which were unfamiliar with the Ada language. Later developers were often less well versed in formal methods and did not use them in their work on the compiler. Several Ada compiler developers at DDC International in Lyngby in 1990.

The early OEM customers included the University of Lund, Defence Materiel Administration, and Ericsson Radio Systems in Sweden Softplan and Nokia Information Systems in Finland Selenia and Olivetti in Italy ICL Defence Systems and STL Ltd in the United Kingdom Aitech Software Engineering in Israel and Advanced Computer Techniques, Rockwell Collins, Control Data Corporation, and General Systems Group in the United States. It held at least three meetings over the course of 19. In a September 1985 meeting in Lund, Sweden, several of the OEM Kit customers formed the DDC Ada Compiler Retargeter's Group. The second business made use of what became termed the DDC OEM Compiler Kit, who could be using the Ada front end for compilers to other hosts or targets or for other tools such as VLSI. DDC-I developed a reputation for quality Ada cross compilers and runtime systems for Intel 80x86 processors. This work was the start of what would become the largest-selling product line for the firm. It began as a joint venture with the Italian defense electronics company Selenia that would target both their MARA-860 and MARA-286 multi-microprocessor computers, based on the 806 architectures, and generic embedded and OS-hosting 806 systems. One of the first cross compilers that DDC-I developed was from VAX/VMS to the Intel 8086 and Intel 80286 the effort was already underway by early 1985. The first business sold both native compilers and cross compilers, with the latter more common since Ada was primarily used in the embedded systems realm.

Ada compiler ĭDC International A/S was housed in a converted textile mill in Lyngby, Denmark, here seen in 1990.ĭDC-I established a business in selling the Ada compiler system product, named DACS, directly to firms, both as software to develop projects in Ada with, and as source code to computer makers and others, who would rehost or retarget it to other processors and operating systems. Located in Phoenix, Arizona, it focused on sales, customer support, and engineering consulting activities in the United States. was founded as the American subsidiary company. Oest was named the managing director of DDC International. Like its originator, it was based in Lyngby, Denmark. Success of the Ada project led to a separate company being formed in 1985, called DDC International A/S, with the purpose of commercializing the Ada compiler system product. As such, it was the first European Ada compiler to meet this standard. But the DDC compiler design was sound and it first passed the United States Department of Defense-sponsored Ada Compiler Validation Capability (ACVC) tests on a VAX/ VMS system in September 1984. Ada was a difficult language to implement and early compiler projects for it often proved disappointments. Among its several projects was the creation of a compiler system for the programming language Ada. The origins of DDC International A/S lay in Dansk Datamatik Center, a Danish software research and development organization that was formed in 1979 to demonstrate the value of using modern techniques, especially those involving formal methods, in software design and development. headquarters and real-time operating systems 3 Ada 95 and explorations of other product lines.
