Technical Field

[0001] This invention relates to the field of embedded development technology, and in particular to a layered embedded software architecture system. Background Technology

[0002] Currently, the embedded industry is developing rapidly, with embedded system technology applied in aerospace, military equipment, shipbuilding, industrial control, traffic management, information appliances, smart home management, networks, and e-commerce. The development of embedded systems can be roughly divided into four stages: ① The single-chip microcomputer (SCM) stage, where software remained without an operating system, using assembly language to implement system functions. Its characteristics included relatively simple system structure and functions, low processing efficiency, very limited storage capacity, and almost no user interface; ② The microcontroller (MUC) stage, primarily based on embedded microprocessors and centered on a simple operating system. Its characteristics included the use of embedded microprocessors in the hardware, with many types and relatively weak versatility; low system overhead and high efficiency; ③ The system-on-a-chip (SOC) stage, characterized by its ability to run on different types of microprocessors, good compatibility, small operating system kernel, and good performance; ④ Embedded systems marked by the Internet, which integrate network interfaces and enable embedded devices to be used in network environments.

[0003] Embedded system development generally has the following characteristics: the scale of the system is getting larger and larger; it is usually developed collaboratively by multiple different independent teams; customer needs are constantly changing; the development cycle of the system is getting shorter and shorter; and the requirements for cost reduction in end products are getting higher and higher.

[0004] Despite advancements in semiconductor technology that have continuously increased processor speeds and on-chip storage capacity, storage space remains precious in most applications, and real-time requirements persist. Therefore, with limited resources, rapidly improving system development efficiency, enhancing product quality, and reducing subsequent maintenance costs has become a significant challenge.

When a user-initiated processing task is obtained, storage space is configured for the connected multimedia device according to the preset allocation mode.

[0018] According to the present invention, a layered embedded software architecture system is provided, wherein the hardware layer includes a device operation level abstraction layer;

[0019] The device operation level abstraction layer is used to parse sensor data and control commands received from the real-time kernel layer, and to store the parsing results in the storage unit of the hardware layer.

[0034] The architecture system, from top to bottom, includes the application layer, system interface layer, real-time kernel layer, and hardware layer, wherein:

[0035] The application layer is electrically connected to the external multimedia device and calls the corresponding interface of the system interface layer according to the type of the multimedia device.

[0036] The system interface layer includes multiple types of interfaces for acquiring data from the multimedia device and transmitting it to the real-time kernel layer;

[0037] The real-time kernel layer calls the corresponding operating system based on the data input from the multimedia device, schedules the running processes and tasks of each operating system, and allocates the storage space in the connected hardware layer to each running process according to a preset.

[0038] The hardware layer includes multiple storage registers and corresponding storage register interfaces, which are connected to the real-time kernel layer.

[0039] According to the present invention, a layered embedded software architecture system is provided, wherein the application layer includes an application scheme layer, an intermediate service layer, and a general system layer;

[0040] The application solution layer is electrically connected to external multimedia devices through an intermediate service layer.

[0041] The intermediate service layer generates a corresponding processing task based on the type of the connected multimedia device and sends it to the general system layer, and then transmits the processing task to the real-time kernel layer through the system interface layer.

[0042] Specifically, the application solution layer utilizes the services provided by the intermediate service layer to implement various functions designed in the interface logic, such as the functions of network TV, set-top boxes, media players, and gaming devices. The application solution layer only depends on the intermediate service layer; all other layers are transparent to the application solution layer.

[0043] The middle service layer includes a service bus and various general services; the service bus is responsible for the registration, scheduling, and message distribution of various services; general services include playback services, interface services, conditional access services, test services, etc., and general services focus on the implementation of various business logics, directly calling various interfaces provided by the general system layer;

[0044] According to a layered embedded software architecture system provided by the present invention, the intermediate service layer includes multiple service buses, through which the business logic of each multimedia device is implemented.

[0046] According to the present invention, a layered embedded software architecture system is provided, wherein the real-time kernel layer is used to provide various system services to users and to preset a storage space allocation mode according to the type of multimedia device. When a user-initiated processing task is obtained, storage space is configured for the connected multimedia device according to the preset allocation mode.

[0047] The real-time kernel layer is responsible for scheduling system running processes and tasks. At the same time, it reuses application components of the software system, including the operating system, file system, and network system, under the "storage-allocation" method.

[0055] This invention employs object-oriented principles to abstract various common functions, enhancing the versatility of functional modules and thereby achieving reusable products, thus improving code reusability. For example, when user requirements change and project application schemes need adjustment, only the application scheme layer needs development, while other layers remain unchanged, significantly reducing the workload of product development. Similarly, when underlying hardware devices are upgraded, only the lowest-level hardware driver layer needs updating, without requiring changes to other code, making hardware device updates very easy.
