High-level modeling-based hybrid launch queue design implementation method and system

Abstract

The invention discloses a high-level modeling-based hybrid launch queue design implementation method and system. The method comprises the following steps of: determining an instruction type and an operand type which need to be supported by a designed hybrid launch queue; establishing a life cycle model of the instruction from entering to flowing out of the transmitting queue; establishing a hybrid transmission queue model adapted to various instruction types and operand types; performing modeling and implementation by using a high-level language aiming at the hybrid transmission queue model, and generating a register transfer level design model; evaluating the register transfer level design model by using a back-end physical design tool; and judging whether the evaluation result meets the expectation or not, if so, ending and quitting, otherwise, giving an optimization suggestion according to the evaluation result, and returning to carry out continuous optimization. According to the method, the requirement of the hybrid transmission queue design can be effectively supported, and the complexity and the design implementation cost of the hybrid transmission queue design are effectively reduced by performing high-level modeling and description on the hybrid transmission queue.
