Abstract: One embodiment of the present invention provides a system for measuring processor performance during speculative-execution. The system starts by executing instructions in a normal-execution mode. The system then enters a speculative-execution episode wherein instructions are speculatively executed without being committed to the architectural state of the processor. While entering the speculative-execution episode the system enables a speculative execution monitor. The system then uses the speculative execution monitor to monitor instructions during the speculative-execution episode to record data values relating to the speculative-execution episode. Upon returning to normal-execution mode, the system disables the speculative execution monitor. The data values recorded by the speculative execution monitor facilitate measuring processor performance during speculative execution.

Abstract: One embodiment of the present invention provides a system that counts speculatively-executed instructions for performance analysis purposes. During operation, the system counts instructions which are normally executed during a normal-execution mode. Next, the system enters a speculative-execution mode wherein instructions are speculatively executed without being committed to the architectural state of the processor. During the speculative-execution mode, the system counts the speculatively-executed instructions in a manner that enables the count of speculatively-executed instructions to be reset if the speculative execution fails.

Abstract: To verify an addition-function of a floating-point adder-subtractor in a processor, parameters such as the number of verification patterns of a verification program are set, a floating-point addition instruction to be verified is created, and operands used for this addition are created at random.

The floating-point addition instruction is computed by using the floating-point adder-subtractor to be verified, and the created expectation value is compared with the operation result. If they do not correspond to each other, the set number of operation patterns is checked. If the number has reached a prescribed value, the operation verification is terminated in the normal manner.

Abstract: A method and system is presented for configuring a group of OCSP (Online Certificate Status Protocol) responders so that they are highly available. Each of the grouped OCSP responders share a common public key.
