QUERYING INPUT DATA
First Claim
1. A method of processing data comprising the steps of:
- receiving a query specifying a query operation to be performed upon a set of input data;
generating a plurality of partial query programs each corresponding to a portion of said query operation; and
executing each of said plurality of partial query programs with all of said set of said input data as an input to each of said plurality of partial query programs.

Abstract
A hardware accelerator 2 for performing queries into, for example, an indexed text log files is formed of plurality of hardware execution units (text engines) 4, each executing a partial query program upon the same full set of input data. These partial query programs may switch between different query algorithms on up to a per-character basis. The sequence of data when loaded into a buffer memory 16 for querying may be searched for delimiters as the data is loaded. The hardware execution units may support a number match program instruction which serves to identify a numeric variable, and to determine a value of that numeric variable located at a variable position within a sequence of characters being queried.

6. A method of processing data comprising the steps of:
-
receiving a query specifying a query operation to be performed upon input data; programming one or more hardware execution units to perform said query, wherein said step of programming programs said one or more hardware execution units to use selected ones of a plurality of different query algorithms to perform different portions of said query operation upon different portions of said input data. - View Dependent Claims (7, 8, 9, 10)

11. Apparatus for processing data comprising:
-
a memory to store a sequence of data to be queried; delimiter identifying circuitry to identify data delimiters between portions of said sequence of data as said data is stored to said memory; and a delimiter store to store storage locations of said data delimiters within said memory. - View Dependent Claims (12, 13, 14, 15)
