Multiprocessor architecture ensures fault-tolerant transaction processing

A recent entry in the expanding market for continuous-processing systems is a fail-safe computer comprised of tightly-coupled general-purpose processors and specialised input/output processors. The processor in Synapse Computer Corp.'s n+1 online transaction-processing system use a proprietary nonwrite-through cache memory and can access reconfigurable, shared main memory over dual 32 m-byte-per-sec buses. Access protection is achieved by integrating the relational database management system, the transaction processing manager and the synthesis operating system into a set of protection spheres. Synchronisation of the database and transaction processing systems provides automatic application checkpointing and recoverability.
