The ARM Cortex Adventure
The ARM Cortex A53 was introduced October 30, 2012.
It has a 64 bit instruction set,
and 1-8 cores per cluster.
The processor runs at 400 Mhz
to 2.3 GHz.
Back in 1982, 42 years ago,
When I was taking CS-113
Programming with Pascal,
Our University Computer
was a CDC Cyber 170...
A SuperComputer based on
the Cray designed 7600...
64 bit words
Memory: 1.3 - 2.6 million WORDS
64 bit Instruction Set
8 692 MB Disk Drives
65 Kw
Water Cooled
The Instructor, Juanita Day,
said that in 20 years or so,
SuperComputers would be
small enough to fit in an
earring ..
I talked to her after class, and
said I didn't think they would
get THAT small, because we
would still need some kind
of User Interface.
I predicted that they would
probably be the size of
a TI SR-50a calculator,
because they would still
need batteries, and charger
ports... and some kind of
Keyboard and Display.
She agreed.
Now, Smartphones have
16+ gigs of memory,
multi-core processors,
and Gigahertz clock speeds.
The only thing they are
lacking is the "Screaming I/O"
to quote Bob Hanzlian...
who was now a University Systems Quality Assurance Programmer
after the folding of Nanodata.
Small Board Computers have
been built from the Cortex A53, including the
and the
It's used by everybody
from Smartphone Manufacturers,
to Amazon's Echo...
All over the world.
