Getting Started With Blackfin Processors 1-7
Introduction
The Blackfin Family of Processors
New high-performance Blackfin processors are available now, while plans
for additional Blackfin processors are designed to offer feature-packed,
future-ready architectures for media-rich applications.
Blackfin Processors (Currently Available)
The ADSP-BF535 was the first released Blackfin processor, followed in
March 2003 by three pin-compatible devices, the ADSP-BF531,
ADSP-BF532, and ADSP-BF533 Blackfin processors. These three devices
offer a range of memory and speed options, providing maximum scalabil-
ity and design flexibility.
