Stratus Computer Inc has committed to Motorola Inc’s forthcoming 88000 RISC microprocessor for a future generation of its fault tolerant systems, with availability planned for the early 1990s. The new machines will be source code-compatible with the company’s present line of XA2000 Continuous Processing Systems, which are based on the Motorola 68020. The Motorola 88000 family is clearly superior to other RISC processors for use in high-performance, multi-processor, on-line transaction processing systems such as those manufactured by Stratus, says Stratus senior vice-president, engineering, Robert Freiburghouse. The company says it has had a RISC technology evaluation project since June 1986 and has developed the necessary compiler optimisation and code generation technology to exploit RISC processors fully: its Cobol, Fortran, PL/I, Basic C and Pascal compilers use a common code-generator and optimiser, so that by changing the code-generator the same source programs can be compiled to run on either Stratus 68000 family or future 88000-based machines. Stratus will be adding further 68000 family models before the 88000-based systems arrive.
