Embodiment Construction

[0065] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.

[0066] Such as image 3 , a kind of RTL graphical description method, comprises the following steps:

[0067] Step 1: Preset special graphics collection;

[0068] Step 2: Establish a multimedia database with special graphic constraints;

[0069] Step 3: storing RTL language elements and grammar rules into the database in the form of regular expressions;

[0070] Each instruction includes an instruction structure and parameters. The instruction structure is limited, but the parameters are infinite (or the amount of data is large). The modulus of the Cartesian product of the two is positive and infinite, which cannot be stored in the database, so only the instruction structure is stored. Enter data. When searching the database, a content-based search is used to find the primary key (ie, the corresponding regular expression) that matches the specifi...

Abstract

The invention discloses an RTL graphical description method which overcomes the defect that three expression manners including a data path, a structural graph and a logistical graph do not involve conversion of an RTL language and a graphical expression manner, creatively invents a method for uniqueness conversion between the RTL language and a signal flow graph, gives full play to advantages including visualization of a graphical language and concreteness of a word language and brings great convenience to teaching and researches.

Description

technical field [0001] The invention relates to a graphical representation of a register transfer language and its conversion with a register transfer language (RegisterTransferLanguage, RTL), specifically an RTL graphical description method. technical background [0002] In digital circuit design, RTL language can simulate the real-time transmission of digital signals / data between register hardware and the logical operation of these signals. It is of vital significance in the research and teaching of digital systems, embedded, computer composition principles and other fields. However, this language has a narrow range of use, and its syntax is complicated and not fixed. Unlike assembly language, it has only a few instructions. In addition, it is very unintuitive, and readers cannot quickly obtain information from it, which has caused great trouble to students and teachers during the teaching process. Therefore, how to intuitively represent the data / signal transfer between ...
