- High-Performance Computer Systems (Ron Ho)
Ron Ho is a Distinguished Principal Engineer at Sun Microsystems,
working in the Sun Labs VLSI Research Group. He received the
Ph.D. degree from Stanford University, Stanford, CA, in 2002.
In 2003, he joined Sun Labs in Menlo Park, CA, where he has been
working on chip-to-chip and on-chip communication technologies,
memory design, and asynchronous circuits.
Over the past several decades, the technology scaling of silicon
circuits has completely transformed the power and performance space
of VLSI chips. However, continued technology scaling also presents
designers with several challenges. Chief among these are the
increasing costs of communication. On a chip, scaled metal wires
are getting slower and slower, while consuming more and more of a
chip's power budget. Off a chip, area solder balls are not scaling
nearly as fast as transistors, making chip-to-chip communication a
worsening bottleneck, even with the liberal use of high-power
serial links on every I/O pad.
SunSPOT (Poornaprajna Udupi)
Project Sun SPOT (Sun; Small Programmable Object Technology) is a snapshot of ongoing research in Sun Microsystems Laboratories.
Established in 1990, Sun Labs, with locations in California and
Massachusetts, is the applied research and advanced development arm of
Sun Microsystems, Inc. Sun Labs is one of the ways Sun invests in the
future -- the Labs is responsible for many of the technology
advancements and inventions that have made Sun a technology powerhouse.
In 2003 researchers at Sun Labs began working on Wireless Sensor
Networks. Over the course of the first year of research, we found that
we wanted more powerful sensor devices that were easier to program. We
felt that our progress was limited by the lack of useful tools and by
inflexible hardware designs. Based on our experience with Java and with
the KVM (both of which were invented in Sun Labs) and its use in cell
phones, we thought that applying Java to development of the platform we
envisioned would help us get past some of these limits.
In November of 2004, Sun Labs started project Sun SPOT to build our
own sensor hardware and to adapt a small, flexible Java Virtual Machine
(Project Squawk) to the sensor platform. Within days of getting our
first hardware running, our eager researchers had developed several
interesting application and we were off and running.
