Embodiment Construction

[0040] The technical solutions of the present invention are clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are all Belong to the protection scope of the present invention.

[0041] In order to shorten the huge gap between the system architecture document and the hardware RTL circuit implementation, it is necessary to use a high-level modeling language between these two stages to describe the function and architecture of the entire circuit system without being caught in the hardware circuit. Complicated signal timing and gate circuits.

[0042] Transaction Level Models (Transaction Level Models, TLM) is a higher level of abstraction than the RTL level. At this leve...

Abstract

The invention relates to the technical field of computer hardware modeling, and provides a GPU chip-oriented rendering output device and device modeling method, and the modeling method comprises the steps: carrying out the transaction-level modeling of the rendering output device of a GPU chip according to a unified modeling language UML and a transaction-level modeling TLM method, wherein the rendering output device comprises a cutting test unit, an Alpha test unit, a depth test unit, a template test unit, a hybrid operation unit, a logic operation unit and an updating buffer area unit. The architecture for quickly evaluating the large-scale hardware system is realized, and the device and method is suitable for early system-level architecture design and development of an integrated circuit; and instructive opinions are provided for the architecture design of the rendering output unit for realizing the GPU chip by utilizing the device.

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a GPU chip-oriented rendering output device and a modeling method. Background technique [0002] With the continuous increase of graphics applications, the early solution of graphics rendering by CPU alone has been difficult to meet the graphics processing needs of performance and technology growth, and the graphics processing unit (Graphic Processing Unit, GPU) came into being. Since the release of the first GPU product by Nvidia in 1999, the development of GPU technology has mainly gone through the fixed-function pipeline stage, the stage of separating the dyer architecture, and the stage of unified dyer architecture. Rendering gradually extends to the field of general computing. The high-speed, parallel features and flexible programmability of the GPU pipeline provide a good operating platform for graphics processing and general parallel computing. [0003...
