Abstract

A hardware device for executing conditional instructions out-of-order and the execution method. An architecture is provided, enabling the hardware device such as a processor supporting the conditional instruction and a computer system to execute the instruction out-of-order. To this end, a conditional execution buffer is provided, and a register of a destination operand of the conditional instruction is renamed to another register. Hence, the hardware device using the conditional instruction can carry out the out-of-order execution, and the execution speed of the hardware device can be greatly improved.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2004-71777 filed with the Korean Intellectual Property Office on September 8, 2004, which is fully disclosed herein for reference. Technical field [0002] The present invention generally relates to a hardware device for issuing and executing conditional instructions and an execution method thereof. More specifically, the present invention relates to a hardware device that issues and executes conditional instructions out of order to improve processor performance. Background technique [0003] Hardware devices such as processors have been improved to have a higher speed of instruction execution and simultaneously issue and execute multiple instructions during a single cycle. [0004] However, branch instructions hinder the performance of the processor and limit the instructions that can be issued. The processor requires an appropriate hardware configuration fo...
