There are a few possibilities:
1) Include only the "concise version", given below. That's my choice.
2) Ask Mike for his opinion. I vote for this if you don't like (1).
3) Include the whole kit and cheezdoodle. I think that's too much,
4) Include the concise version, plus links. That also might be
confusing, without the background information.
5) Give the concise version now, possibly amend it as appropriate
after the presentation.
I'd rather not have to try to cut down his rambling notes, and
suspect that posting them would sort of steal his thunder.
Submit your votes, or suggestions.

Subject: SVLUG talk outline
Here's a rough outline of my portion of the talk for SVLUG.
Mike earned a BSCS from the University of New Mexico in 1982 and a
MSCS from the University of Illinois in 1984. He spent ten years as a
member of Harris's Advanced Tecnology Department doing research in
VLSI CAD, parallel processing, and X. More recently, he has worked on
desktop and settop boxes for SGI, distributed parasitic extraction for
Mentor Graphics, and secure fingerprint sensors for Veridicom. He is
currently the CTO of A Cool Computer Science Company doing work with

What kernel version/source tree?
configuration: make ???config
static char log_buf[LOG_BUF_LEN];
becoming intimate with init/main.c
Got a shell prompt! What's next?
You're 5% done!
keyboards: PS/2 and scanned
user land tools/apps?
What's different about an embedded Linux?
Lack of resources:

Mike McDonald's Background:
NEC Electronics 1997 - present Working with NEC Vr CPUs Vr4102,
Vr4111, Vr4121, Vr4122, Vr4181 Worked on porting and testing software
device drivers for WINCE Software on NEC Electronics Reference boards
Supporting customer questions about the WINCE software Suggested NEC
Electronics to start supporting LINUX software on our Vr4181 Osprey
Handheld referemce design. Supported NEC Electronics to contract
porting Linux software on Vr4122 Harrier reference platform.
He is actively working with several Linux Vendors to come up with
Linux Solutions for NEC's Vr cpus. These linux solutions include
kernel porting, driver development and application programs. The
market focus is on digital consumer products.
November 13 2000
TOPIC: Porting Linux Kernel to an Embedded System with less of everything.
Questions that the Audience may want answered.
1. How much does it cost? 100K Dollars
2. How long does it take to port the Linux Kernel? 5 - 12 Months
3. How long does it take to port the Linux Applications? Forever,
because something new is always coming down the line. Seriously, a
few minutes to a couple weeks porting from x86 software to NEC Vr
MIPS. Cross Compiling has its own set of issues, with the libraries
supported and directory path names.
4. NEC's interest is in selling CPUs. Customers are asking for the
Linux software solution. NEC wants their business and is willing to
help the free software movement to port Linux software onto NEC Vr

Brad LaRonda started this off with a CVS tree and a Vadem Clio
There are 3 or 4 things needed to place an IC into a design. Working
IC, Data Sheet, Reference Board ( Hardware HOWTO ), and working
software, ( ie the Dance Step, the sequence, the register setup)
1.) The working Chip with most bugs fixed.
2.) The data sheet describing the chips pin out and registers.
3.) A working Software example that shows the order of reading and
writing those registers.
This Software has to be given away without encumbrance. ie Would you
like to see working software. Well here is an example. Propiertary
Software solutions/drivers usually need an NDA signed with a
potential customer before the customer can have the software. We ask,
"Did you sign the NDA? No, Oh sorry, I cant show the working
Company X driver software."
Linux can be given away freely and shows the pattern of accessing the
registers with known working tested software.
For example, in 1949 the magazine Popular Mechanics expressed the
opinion that "Computers in the future may weigh no more than 1.5
tons." Actually, with some of today's computers weighing a few
ounces, the magazine was sort of correct. Thomas Watson, the chairman
of IBM, stated in 1943 that "there is a world market for maybe five
computers." The founder of Digital Equipment Corporation said "There
is no reason anyone would want a computer in his home."
Today, why would you want to play songs on your computer. Nobody
would want to do that when you can buy a $50 CD-ROM or a $20 cassette
player or a $10 FM radio. Here is Napster, an idea from a college
Dr. Williams observed we survived all these errors because "the
'experts' making false predictions had not the power to impose their
vision on the future of others." He adds, "For this reason alone we
should not allow experts, no matter how smart they are - or think
they are - to control any aspect of our lives."

Olivetti MIPS machines Brad LaRonde in New York Mike Klar Jay

plus others listed on http://linux-vr.org
Who supports Linux on NEC Vr Cpus today? http://Linux-VR.org
MontaVista Software for Vr4181 & Vr5476 VioSoft for Vr5476,
Vr5074 reference boards. Cool California Software for Vr4122 Linux
Kernel www.coolcs.com Debian Linux Century Software for
MicroWindows, ViewML, graphics driver
Who will support Linux Vr in the future? Agenda Computing and the VR3
Linux Handheld in January 2001 Linux Users like yourself in the
audience when you write Linux applications for these VR3 Units.
Why use MIPS over x86?
1.) Cost. $50 up for x86 $30 and down for MIPS
2.) Power 20 Watts 2 Watts Vr5432 350 milliWatts Vr4122,
Handheld use We don't sell a '12V DC ball bearing FAN' with every
CPU. This is advantage for embedded area, like a server in wiring
closet with out air conditioning.
3.) MIPS Code advantages 32 general purpose registers with a full
64bits Where you waiting for Itanium to do a full 64bit register to
register compare? the Linux VR kernel only supports 32bit
4.) Speed, even with the Mhz Clock rating of 500Mhz for x86, a
200Mhz MIPS can get equivalent work completed.
Monitor Code in the EPROM
2.) NEC Debug Monitor with TFTP download
AC97 Stereo Sound
USB 1.1 4 types of transfers
PS/2 Keyboard / Mouse Drivers
Touch Panel Drivers
V.90 Modem Solutions
Non Volatile RAM
Integration of applications to the embedded system.
By the seat of your pants. This is difficult work to accomplish even
if it compiles easily with the x86 Linux
Chant, Make config, Make Dep, Make Oops, Make Clean, and repeat daily.
Voice over IP on Linux
efone May 31st 2000, 15:56 EST
Efone is a distributed internet phone system. It features a voice
sending/receiving client (an internet phone) and a central server
(administered via the Web) where users' information (name, nick,
password, current IP) is stored. It resembles a combination of ICQ
and Internet phone.
