Problems solved by technology

[0003] However, due to the limitations of hardware processing capabilities, in order to pursue higher efficiency, these virtual machine devices are developed for specific upper-level embedded system software, which have poor versatility and single functions, and often can only provide simple abstract packaging. functions, but cannot provide the middleware functions commonly required by many upper-level embedded application software, such as: virtual task scheduling, communication between different processors, distributed database, high reliability, message tracking and debugging, etc., because these functions are provided Often means reduced system processing power and low efficiency

Embodiment Construction

[0012] Such as figure 1 , the virtual machine (VM) device 2 of the present invention runs on the real-time operating system 3, provides services to the embedded system software 1 of the upper layer, not only as the operating platform of the embedded system software 1, but also as its development platform. The virtual machine device 2 is developed on the real-time operating system 3, and the development tool used is Tornado (an integrated development environment based on VxWorks). Hardware 5 is a complete NodeB (base station) system, which includes a system control single disk and multiple business processing single disks, and each single disk has an MPC860 (a processor chip produced by Motorola, USA) processor , The single disks are connected through the industrial bus, which can exchange information in real time. On a single disk, there are board support packages and device drivers4. The real-time operating system 3 adopts Vxworks (a current mainstream embedded real-time op...

Abstract

The unit comprises databank module, interprocess communication module, high reliability module, debugging module, task dispatching module, expension protocol module, clock module, internal memory module and multiintertask communication module. The unit not only provides an operation and development platform with strong function for system software in top large-scale of embedded type to realize independence of top and bottom layers and to increase portability of top application code, but also can collectively transfer the function of some universal modules in top application software into the virtulizer for realization through intermediate component contained with generality in the virtualizer.

Description

(1) Technical field [0001] The invention relates to a virtual machine device for embedded system software development. (2) Background technology [0002] The development of early embedded system software is based on a specific real-time operating system, which can make full use of the performance of the operating system, but the embedded system software is highly dependent on the underlying operating system and hardware, and the portability of the program code is poor. . Later, in the development of large-scale embedded software, in order to meet the needs of the upper-level embedded software code to be easily transplanted to different real-time operating systems, and to realize the independence between the upper-level embedded system software and the lower-level real-time operating system, many embedded system software Most developers develop a set of virtual machine devices on top of real-time operating systems. This device provides a relatively standard set of APIs (appl...
