TALK:

"A High Temperature Embedded Network Interface in Software"

ABSTRACT

A bit-banged CAN network interface running at 390 degrees on an 8051?
This talk describes HSCAN, an experimental implementation of a
communication network protocol bridge for a high-temperature (200 C /
392 F) application. The software uses a new compilation technique called
Software Thread Integration (STI) to interleave multiple real-time
program threads for efficient concurrent execution, allowing an
off-the-shelf, high-temperature, low-speed 8 bit microcontroller to
translate messages between a CAN bus and a serial UART data link. The
prototype system has been built and baked for 100 hours (while running)
to demonstrate the feasibility of using STI in real-world applications.
STI provides the techniques needed to automate the tedious
hand-scheduling of time-sensitive code from multiple simultaneous
threads so common in cost-driven microcontroller-based applications. STI
can be used to eliminate hardware, or perform functions unavailable in
hardware.

BIO

Alex Dean is the lone embedded-systems-oriented Ph.D. student of John
Shen. He got his BSEE at UW-Madison (1991) and his MSEE at CMU (1993).
He worked for a couple of years in an industrial r&D lab investigating
and designing architectures and communication networks for embedded
systems (cars, jet engines, elevators, etc.) and then returned to CMU
with grant money (including a healthy travel budget) to work on compiler
support for embedded systems. For the past three years he's been
bouncing back and forth between here and there, doing things such as
HSCAN. On average, he presents at conferences 4428 miles away from
Pittsburgh.
