Although Compagnie des Machines Bull SA sold its Swedish compiler company Diab Data AB as long ago as December 29 last year, the sale is only now being disclosed. The buyer was Sunnyvale, California-based Integrated Systems Inc, which says it didn’t volunteer the information until now because it wanted Diab Data, whose US base is in Foster City, California to have time to establish a track record as an independent unit. Diab Data specializes in compilers, including C, C++ and Fortran, for embedded processors. Integrated Systems says it acquired some technology, related assets and all shares of Diab Data but did not say how much it paid for the company.
