| Cool-* (read
CoolStar) is
our
flagship research; it is a compiler-enabled, statically speculative, low-power
microprocessor architecture.
Our goal is to reduce power and energy
consumption by a suite of combined
architecture-compiler techniques. Our
main philosophy is leveraging static
information speculatively and providing
support for static execution modes in
addition to other circuit and
architecture level techniques. We
estimate that our approach can reduce
power (energy) by 40-70% of a
state-of-the-art low-power
microprocessor such as the StrongARM. We
have developed techniques in different
areas of the processor, the Cool-*
suite, e.g., Cool-Cache (see Micro-34,
Dec 2001),
Cool-Fetch (ACM Computer Architecture
Letters, 2002, May), Cool-Mem
(to appear in ASPLOS 2002), Cool-Run (in progress),
Cool-Ways(submitted), Cool-Watts (in
progress), MiniMax Cache (in HPCA
2002)). Check the list of publications
for already published works and check
back later because we have many
interesting approaches cooking in the
pipeline .....

FlexCache
is
a
fully compiler-enabled memory
system.
It integrates software
cache partitions,
compiler managed
partitions, and
conventional cache
partitions into a uniform
memory system framework.
We plan to target
FlexCache to:
- synthesize
caches for reconfigurable
architectures,
provide
predictable
memory
systems in real-time
embedded systems,
improve
caching
efficiency in
microprocessors,
reduce
power consumption in
memory systems.

Euphoria
and EuphoriaLite
focuses on
scalable software
infrastructure for global
dynamic content
management applications
on cluster of
workstations and
multiprocessors, as well as in
distributed embedded systems.
Euphoria implements
it's scalable/adaptive resource
management based on:
- non-intrusive
introspection
-
byte code
level analysis and
transformations (Java and .NET CLR),
- individualized
content management,
- object
cache store management,
- ,
- analytical
forecasting models.
- web
caching
- wireless
client integration
HTML/XML-WAP
- real-time
JVM for resource
constrained devices
From the
outside it aims to be
compatible with
application server and
client software
technologies such as
defined in J2EE, J2ME,
CLDC, WAP, KVM
specifications and have
support for both
traditional web based and
wireless clients.

in SMP/NUMA/single-chip
multiprocessors
most recently we have made lots of
progress on this especially related to
synchronization coherence protocols (our
new concept :-)).
