Problems solved by technology

These three methods have their own advantages and disadvantages. The execution speed of assembly language is fast, but it is difficult to learn, the development efficiency is low, the versatility is poor, and the readability of assembly language is poor. It is necessary to write functions by yourself, requiring users to have a deeper understanding of hardware; GVBASIC language is easy Learning, there are many applicable models, but the speed is slow, and the functions are limited and unstable. The object code of GVBASIC language is a little larger than that of assembly language, but there are few functions, and the programming efficiency is much higher than that of assembly language. It also requires users to have certain knowledge of hardware. level of understanding; WINIDE language is easy to learn, fast, rich in functions, and high in programming efficiency, but there are certain restrictions on the size of the system's SRAM and programs. The compiled code cannot exceed 32kbytes, and there are few applicable models.
[0003] Moreover, due to different models, the applications required to be used in Wenquxing are also different, so it is necessary to download suitable applications for each type of low-end handheld terminal, which increases the development cost and is inconvenient to use. Not able to achieve cross-platform

Embodiment Construction

[0037] The GVmaker language is a cross-platform language. The cross-platform mentioned here means that the object code of the same program can run directly on different hardware platforms without modification, which is different from portability. However, cross-platform is not absolute, but relative. Absolutely cross-platform languages ​​either don't exist or are useless. For example: There is a GVmaker program that needs 20KB of memory to run, so this program obviously cannot run normally on a platform with only 8KB of memory. So in order to ensure that all GVmaker programs can run on the 8KB memory platform, is it possible to limit all GVmaker programs to only use 8KB of memory? The answer is that you cannot limit the capabilities of the language itself for absolute cross-platform capabilities.

[0038] FIG. 1 shows the overall architecture 100 of GVmaker technology. As shown in Figure 1, in order to achieve the versatility of the program, the GVmaker technology adopts t...

Abstract

A hand terminal system comprises development unit utilizing cross-platform language to develop application program used in hand terminal and hand terminal utilizing virtual machine to interpret said application program to be code being able to be executed by machine for realizing preset function of said application program.

Description

technical field [0001] The invention relates to a hand-held terminal system, which can apply the same application program to different types of hand-held terminals without any modification, so as to achieve the purpose of cross-platform. Background technique [0002] At present, there are many types of electronic dictionaries, and their development methods are different, and their running effects are also very different. The development methods previously owned by Wenquxing mainly include 6502 assembly language, GVBASIC language and WINIDE language (C language). These three methods have their own advantages and disadvantages. The execution speed of assembly language is fast, but it is difficult to learn, the development efficiency is low, the versatility is poor, and the readability of assembly language is poor. It is necessary to write functions by yourself, requiring users to have a deeper understanding of hardware; GVBASIC language is easy Learning, there are many applic...
