Problems solved by technology
Especially in the military field, foreign imported commercial GPU chips have hidden dangers in safety, reliability, security, etc., and cannot meet the needs of the military environment.
[0003] Common modeling methods include UML, SysMl, etc. UML modeling methods have the advantages of specification, easy understanding, independent of development language, and clear boundaries. At that time, its shortcomings were that it could not express non-functional requirements. Non-functional requirements such as non-functional requirements are helpless, and it has a relatively coarse granularity, and many details cannot be described, and other tools are needed for assistance.

Embodiment
[0047] see Figure 1-3 , a TLM device of a GPU projective transformation module based on a sysML view, where sysML refers to a system modeling language, GPU refers to a graphics processing unit, and TLM refers to transaction level modeling. It is characterized in that it includes a structure definition diagram of the GPU projection transformation module, a data interface definition diagram of the GPU projection transformation module, and a behavior flow chart of the GPU projection transformation module. The structure definition diagram of the GPU projection transformation module presents the internal components, port sockets and interconnection information of the GPU projection transformation module unit; the interface diagram of the GPU projection transformation module shows the interface function information provided by the GPU projection transformation functional unit itself; the GPU projection transformation module The behavior flow chart is the activity diagram, which sho...

The invention relates to the technical field of computer hardware modeling, in particular to a TLM device of a GPU projection transformation module based on a sysML view and an operation method. The device comprises a PTU_CORE assembly and a Monitor assembly. The operation method comprises the following steps: 1) initializing variables; 2) waiting for the state change of the projection transformation data storage unit; and 3) converting the received data. According to the TLM device of the GPU projection transformation module based on the sysML view and the operation method, the problem that the number of fragments passing the depth test in the current drawing process is inquired is solved, so that whether a group of geometric figures are visible or not after the depth test is carried outcan be judged, and the simulation speed is increased.
Description
technical field [0001] The invention belongs to the technical field of computer hardware modeling, and relates to a TLM device of a GPU projection transformation module, in particular to a TLM device and an operation method of a sysML view-based GPU projection transformation module. 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. At present, my country's GPU research and development capabilities are weak, and a large number of commercial GPU chips imported from abroad are used in display control systems in various fields. Especially in the military field, foreign imported commercial GPU chips have hidden dangers in safety, reliability, security, etc., and cannot meet the needs of the military environment. [000...
