Appeal No. 2003-0376
Application 09/364,281
The disclosed invention pertains to a data processing
system having redundant hardware partitions that provide dynamic
repair capability. If an error is detected in a particular
hardware partition, the data stream assigned to that hardware
partition is reassigned to another of the plurality of hardware
partitions. The data streams are assigned to the hardware
partitions using a hashing circuit and a hashing selection
circuit. When an error is detected in a particular hardware
partition, the hashing selection circuit reassigns a data stream
by changing the hash implemented by the hashing circuit.
Representative claim 1 is reproduced as follows:
1. A processor, comprising
execution resources;
data storage; and
an instruction sequencing unit, coupled to said
execution resources and said data storage, that supplies
instructions within said data storage to said execution
resources;
wherein of said execution resources, said data storage,
and said instruction sequencing unit, at least said execution
resources are implemented with a plurality of hardware partitions
of like function for processing a respective one of a plurality
of data streams, and wherein said instruction sequencing unit
includes a hashing circuit that assigns said plurality of data
streams to said plurality of hardware partitions based upon an
address hash of addresses associated with instructions within
said plurality of data streams, said hash being selected by a
hash selection circuit within said processor, and wherein if an
