Analog Devices Blackfin

A2E have considerable experience in developing hardware and software solutions using the Analog Devices Blackfin DSP running at up to 600Mhz.

We have designed products using BF527, BF531, BF533, BF537 and BF561 Blackfins, and have used multiple Blackfin variants working together on single board solutions to produce products with over 2900 MIPS performance yet low power usage.

A2E can provide rapid prototyping, producing custom hardware daughter-boards for the Blackfin EZKit boards, along with bespoke drivers and software. We create software solutions from the lowest level, through to Analog Devices' System Services layer and VDK, along with optimised embedded Linux solutions with rapid boot time and low memory footprint.

Using Blackfin Linux provides instant access to a wealth of drivers and applications, and a ready familiar platform for your own code to run on an embedded device.

A2E Linux Blackfin solutions include:

• Access up to 256MB RAM
• Multiple Serial (SPI) and Parallel Flash
• 10/100baseT ethernet with full TCP/IP networking
• Network filing systems (NFS, SMB)
• Web server
• AC97 audio in/out
• I2C sensors and IO expanders
• USB2.0 device and host
• Fully wired RS232 with hardware handshake control
• RS422/RS485
• High speed parallel input from megapixel CMOS sensors
• SD card with MSDOS/VFAT filing sytem
• Interfacing to slave Blackfin and CPLD devices
• Very low power sleep modes with true instant restart
• Flash upgrade with redundancy failover
• Ultra low power consumption using 1.8V supply
• JTAG debug
