Introduction

RDK-B components are designed to avoid platform or silicon dependencies. Hardware Abstraction Layer (HAL) defines a standard interface for hardware vendors to implement. The HAL layer abstracts the underlying hardware like MOCA, Wi-Fi, etc. through a standard set of APIs defined as part of RDK-B HAL for the respective components. This HAL layer is implemented per platform and the rest of the components can be compiled to run on the new platform without major modifications.

The HAL in RDK-B Architecture section gives an overview of CCSP framework's Hardware Abstraction Layer.

HAL can be common-HAL or component-specific-HAL

•  A common HAL provides the necessary abstraction to all the CCSP components to interface with other common hardware components.
•  Components may define a component specific HAL to hardware drivers, that are only used by that component

Component Specific HAL

HAL APIs will be available in the CMF repo path: "../rdkb/components/opensource/ccsp/hal/source/"
