Summary
|
|||
|
|
*******
|
|||
|
|
|
|||
|
|
Armino software is divided into middleware layer, component layer and application layer.
|
|||
|
|
Armino Armino abstracts the coupling dependence of software on hardware platform and realizes
|
|||
|
|
the shelving of software platform. Through this shelf design and rich SDK APIs, SDK developers
|
|||
|
|
can design and develop more efficiently.

Software Architecture
|

|
|
*********************
|
|||
|
|
|
|||
|
|
Armino SDK can flexibly support different product software architectures.
|
|||
|
|
|
|||
|
|
1、 Based on Armino SDK's own software architecture
|
|||
|
|
See the legend of Architecture Overview for the overall framework of the solution.
|
|||
|
|
In this solution, the operating system has been decoupled and adapted.
|
|||
|
|
The current Armino solution supports FreeRTOS and LiteOS.
|
|||
|
|
|
|||
|
|
|
|||
|
|
2、 Based on the developer's own software architecture
|
|||
|
|
Armino SDKThe Armino SDK is compatible with a variety of software ecosystems,
|
|||
|
|
facilitating developers to integrate the Armino chip solution into their own
|
|||
|
|
mature product software architecture.

Hardware Layer
|
|||
|
|
**************
|
|||
|
|
|
|||
|
|
Hardware layer, namely hardware layer, refers specifically to the hardware of BEKEN solution.。
|
|||
|
|
|
|||
|
|
|
|||
|
|
Middleware Layer
|
|||
|
|
****************
|
|||
|
|
|
|||
|
|
Middleware layer, namely the middle layer, is an abstract layer for the underlying hardware and
|
|||
|
|
upper components. Through the M-server, we can seamlessly switch between different solutions.

Armino middleware
|
|||
|
|
|
|||
|
|
As shown in the figure:：
|
|||
|
|
- arch, It includes related functions of chip architecture, such as arm, riscv, general interrupt processing, boot, pmp, etc.
|
|||
|
|
- soc, Chip related special processing and related configuration.
|
|||
|
|
- dirver, Driver layer, including various peripheral drivers, such as I2C, GPIO, UART, etc.
|
|||
|
|
- compal, Components abstraction layer. In order to enable third-party open source components to function on the armono platform while reducing code coupling.
|
|||
|
|
- boards, Board level configuration is related, covering some engineering configurations of specific projects.
|
|||
|
|
|
|||
|
|
Component Layer
|
|||
|
|
***************
|
|||
|
|
|
|||
|
|
The Components layer, or component layer, is a service component that contains many third-party open source or self developed by armono. Developers can configure defconfig in the middleware layer to switch related component services.
|
|||
|
|
|
|||
|
|
Application Layer
|
|||
|
|
*****************
|
|||
|
|
|
|||
|
|
The application layer is organized under the projects directory, and the last level of the CmakeList directory is the building entry for a complete solution. It carries the differentiation of different projects and the configuration set of different product solutions.
