Getting Started With Blackfin Processors
What are the recent Dhrystone and Whetstone benchmarks?
The most recent Dhrystone and Whetstone benchmarks are the following:
• Dhrystone: 380225.1 Dhrystones/sec (-O3 -ffast-math –mfast-fp)
• Whetstone: 176.5 Whetstone MIPS (–O3 -ffast-math –mfast-pf)
What is the µClinux footprint?
The default kernel is 500 Kbytes – 1 Mbytes
What size flash is recommended?
A workable image will fit in 4 Mbytes of flash memory (serial, NAND or
parallel NOR).
What debugging tools are supported?
The following debugging tools are supported:
• GDB with simulation and JTAG support
• KGDB (for kernel and driver development)
• GDBSERVER (over ethernet or serial port)
• ICEBear USB ICE (for use with GBD). Visit this URL:

• IGLOO (parallel port) ICE (for use with GBD). Visit this URL:

Do real-time and general-purpose kernels coexist?
ADEOS has been ported to the Blackfin processor. ADEOS is a hardware
abstraction layer allowing a real-time kernel and a general-purpose kernel
to coexist. ADEOS supports the kinds of dual-OS Linux environments
that are achieved using RTLinux or RTAI, without making use of the
technology that is the subject of the RTLinux patent.
