57 ABSTRACT A Single chip microprocessor or memory device has repro grammable characteristics according to the invention. In the case of the microprocessor, a fixed processing cell is pro Vided as is common to perform logic calculations. A portion of the chip Silicon real-estate, however, is dedicated a programmable gate array. This feature enables application Specific configurations to allow adaptation to the particular time-changing demands of the microprocessor and provide the functionality required to best serve those demands. This yields application acceleration and in System-specific func tions. In other cases the configurable logic acts as network interface, which allows the Same basic processor design to function in any environment to which the interface can adapt.

The invention also concerns a memory device having a plurality of memory banks and configurable logic units asSociated with the memory …
