• Isolates the hardware from the software. This means that the application software can be hardware independent, greatly reducing the cost and risk of migrating to a new hardware platform.
• Allows the driver code to be reused, leading to greater efficiency and performance.
• Allows the application writer to access hardware services easily, by reducing ambiguity in the usage of the hardware.
• Enables the user to constrain the functions needed in the peripherals and to eliminate unnecessary "hardware features" that make the interface more difficult.

Libraries - SDK components are grouped into software libraries. There are three major sets of libraries:

• Core Libraries - include interrupt handling, memory management, timer, I/O, and Board Support Packages (BSPs).
• DSP Function Libraries - provide general purpose DSP algorithms for basic fractional math, trigonometric math, vector and matrix manipulations.
• Domain Specific Libraries - focus on more specific application areas. These libraries may contain DSP algorithms for modem applications, image processing applications, and others.

Services - SDK defines and implements the following services:

• Board Support Package
• Interrupt Handling
• Memory Management
• I/O
• Timers
  

Rules and Guidelines - To achieve a goal of truly portable and reusable software, software developers must go beyond the use of common APIs and services. SDK defines programming rules that apply to all applications and algorithms on all DSP architectures regardless of the area of application. These rules must be followed in order for software to be SDK-compliant. Guidelines, on the other hand, are strongly suggested notations that should be obeyed but may be violated by SDK-compliant software.

Reference Applications - To minimize the learning curve, SDK contains a large number of reference application designs. These applications serve as an example of how to implement user-specific designs which use SDK features.

Documentation - It contains the most comprehensive and complete set of manuals, data sheets, application notes, and white papers designed to help you find quick answers for your questions.
