It is actually an ARMv7a. This a LATER chip than the ARM11, much less the ARM9. The NEON is a powerful 128 bit wide SIMD processor capable of doing floating point arithmetic.
Bob This is definitely going to make a VERY nice low power SDR board. Another we should consider is the OMAP-L137 which has ARRL SDR Working Group Chair Member: ARRL, AMSAT, AMSAT-DL, TAPR, Packrats, NJQRP, QRP ARCI, QCWA, FRC. "Trample the slow ....

The Beagle uses a Cortex-A8 which is an armv7 architecture processor. Confusing? Yes. An arm9 processor uses an armv5 instruction set. (From memory) The arm7 technical reference is not public, but if you ask nicely you can get a copy. Needing it to implement NEON based filters for GNU Radio was a good reason. Bottom line: companies are still "funny" about doucmentation for high end products, but attitudes are changing very slowly.
