The present invention is directed towards systems and methods for generating and displaying the difference between a primary result set and a secondary result set. According to the present invention, a method for displaying the difference between a primary result set and a secondary result set for a query comprises generating a primary result set and a secondary result set, the primary result set and secondary result set generated according to one or more respective disparate search algorithms. A difference result set is determined according to a difference between items in the primary result set and second result set, which is displayed to a user.

Difference control for generating and displaying a difference result set from the result sets of a plurality of search engines

Indication of exclusive items in a result set

Presentation of differences between multiple searches

A processor element, structured to execute a 32-bit fixed length instruction set architecture, is backward compatible for executing a 16-bit fixed length instruction set architecture by translating each of the 16-bit instructions into a sequence of one or more 32-bit instructions. The 32-bit instruction set architecture includes &ldquo;prepare to branch&rdquo; instructions that allow target addresses for branch instructions to be set up in advance of the branch. The 32-bit prepare to branch and branch instructions are combined to execute a 16-bit branch instruction coupled with a 16-bit Delay Slot instruction.

Emulating execution of smaller fixed-length branch/delay slot instructions with a sequence of larger fixed-length instructions

A system for predicting branches in a computer system is provided having a memory containing program code comprising a plurality of instructions, said instructions including branch instructions and prediction operations, a store containing an reference to a branch instruction in said program code and corresponding prediction data, means for modifying said prediction data in response to said prediction operations contained within said program code, means for predicting an outcome of a branch instruction based on the prediction data to generate a prediction, and means responsive to the prediction for predicting the outcome of a branch instruction. A method for predicting branches is also provided.
