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
