Re: New ARM Cortex Microcontroller Product Family from STMicroelectronics

I'm with Jon on this, the semantics matter little; but it would be
good to answer the simple question "Can it execute code from RAM?"
- in some systems, that is useful.

In the case of my original article:
http://www.microcontroller.com/news/arm_cortex_stm.asp
the answer is YES - the ST part can execute code from RAM off the data (system) bus. Of
course, there will be extra cycles.

Back when I was but a fledgling FAE, in my presentations I used to label architectures
as Harvard, Modified Harvard, Von Neumann, etc.

In PPT presentations, engineers would ALWAYS debate amongst themselves as to the
differences between these architectures, and sometimes whether or not Von Newman (What,
Me Worry???). was spelled right...

What you decide to call the architecture is much less important than what you decide to
do with it.
