HAL: Fast matching algorithm one, Introduction The generation system of forward inference has been applied in various fields. The basic structure of these production systems is divided into three parts. The first part is the inference engine of the control rule. The second section is a working m

1.HAL (handerware abstraction layer, hardware abstraction layer) is a set of libraries built on Linux programs that are not part of the kernel, but that belong to the application layer on top of the kernel.2. Reasons to join Hal in Android: There are generally two types of code in Linux drivers: code to access hardware registers and business logic code. There is no secret to the code that accesses the hardw

First, Android added Hal's main purpose in addition to avoiding direct access to the Linux driver, an important reason is to protect the business or personal core business logic. Linux drivers in traditional Linux systems generally have two types of code: Access to hardware register code and business logic code, for access to hardware register code, is called the Linux kernel standard function to operate and there is no secret to say. For business logic code, there are some trade secrets or tech

Why add HAL to Android Goggle for Android to join HAL mainly has the following purposes:The calling interface for unified hardware. Because HAL has a standard calling interface, HAL can be used to mask Linux to drive complex, non-uniform interfaces.Fixed the GPL copyright issue. Because the Linux kernel is based o

In the last two articles, we described how to write drivers for the hardware of the Android system, including how to implement kernel drivers in the Linux kernel space and implement hardware abstraction layer interfaces in user space. Both are implemented to provide hardware access to the upper tier, providing hardware services for the application frameworks layer of Android. We know that Android applications are written in the Java language, and hardware drivers are implemented in C, so how doe

Nineth Hardware Abstraction Layer: HALThe Nineth chapter mainly introduces a set of library HAL (Hardware abstraction Layer) built on Linux driver. This library is not part of the Linux kernel, but rather belongs to the application layer on top of the Linux kernel layer.Google's main purpose of adding Hal to Android is to protect "private property" in addition to avoiding direct access to Linux drivers.

The Nineth chapter:As long as you're talking about hardware abstraction Layer Hal,hal is a set of libraries built on Linux drivers. Hal is not part of the Linux kernel but is located on the Android system runtime layer. The first thing to say is the benefits of joining HAL. Includes: Unified hardware call excuse, to so

9th chapter: Hardware Abstraction Layer HAL1.HAL (Hardware abstraction layers, Hardware abstraction layer) is a set of flip fonts built on Linux drivers. This library is not part of the Linux kernel, but rather belongs to the application layer on top of the Linux kernel layer.2. Steps to write a Linux driver that supports HALWriting a Linux driver that supports HAL is a bit more complicated than writing a n

This course solves the problem of how to understand the beginner's mind of Android architecture design and develop a featured product with Android system with deep customization and soft and hard integration capability.The course takes the five core of Android: HAL, Binder, Native service, Android service (and the example of AMs and WMS), the View system as the spindle, a one-time thorough mastery of the essence of Android.The reason why the developme

This chapter focuses on the hardware abstraction layer: HAL, which is a set of libraries built on Linux drivers. Just started to introduce why to add HAL to Android, the purpose is three, one, unified hardware call interface. Second, solve the GPL copyright issue. Third, for some special requirements.

In this section we examine the hardware abstraction layer: Halhal, a set of libraries built on Linux drivers. Just started to introduce why to add HAL to Android, the purpose is three, one, unified hardware call interface. Second, solve the GPL copyright issue. Third, for some special requirements. You can use the HAL code located in user space to assist the Linux driver in doing some work.

Nineth Hardware Abstraction Layer: HAL9.1 Why should I join Hal in Android?First, Google added HAL's main purpose for Android, in addition to avoiding direct access to Linux drivers, there is one important reason, that is, to protect "private property." -ForThose who both want to publish stubble · Android, Linux drivers, and businesses or individuals who don't want to expose their core business logic, are simply the gospel.HAL is not part of the Linux

1. HAL is a set of libraries built on Linux drivers that are not part of the Linux kernel but belong to Linux The application layer above the kernel layer. 2, Google for Android to join HAL mainly has the following purposes:Unified hardware Call interface, solve the GPL Copyright issues. 3. The drive to join HAL allows applications to not care about how Linux dr

Hardware Abstraction Layer: HALGoogle to join HAL for Android mainly has the following purposes:1. The calling interface of the unified hardware. Since HAL has a standard calling interface, HAL can be used to shield Linux drivers from complex, non-uniform interfaces.2. Fixed the GPL copyright issue. Because the Linux kernel is based on the GPL protocol, Android i
