Introduction - Analog Devices VisualDSP++ 5.0 Service Manual

1 INTRODUCTION

This manual describes the system services and device driver architecture
for Analog Devices embedded processors.
The system services form a collection of functions that are commonly
found in embedded systems. Each system service focuses on a specific set
of functionality such as direct memory access (DMA), power management
(PM), interrupt control (IC), and so on. Collectively, the system services
provide a wealth of pre-built, optimized code that simplifies software
development, allowing you to get Blackfin processor-based designs to
market more quickly.
The device driver model provides a simple, clean and familiar interface
into device drivers for Blackfin processors. The primary objective of the
device driver model is to create a concise, effective, and easy-to-use
interface through which applications can communicate with device
drivers. Secondarily, the model and device manager software significantly
simplifies the development of device drivers, making the development of
new device drivers very straightforward.
Currently, the system services and device drivers are available for use with
the following Blackfin families: ADSP-BF531/532/533,
ADSP-BF534/536/537, ADSP-BF538/539,
ADSP-BF542/544/547/548/549, ADSP-BF522/524/526,
ADSP-BF532/525/527, and ADSP-BF561.
