23 Claims

1. A database processing system comprising:

a processor operable to process queries to a database; and

a coprocessor subsystem to offload database operations from the processor, the coprocessor subsystem including:

a coprocessor operable to:

receive numeric data tuples retrieved from the database;

filter the numeric data tuples; and

provide the filtered numeric data tuples to the processor; and

a string accelerator to offload string operations from the coprocessor, the string accelerator operable to:

receive string data tuples retrieved from the database;

filter the string data tuples; and

provide the filtered string data tuples to the coprocessor.
