 		Workshop on Hardware Support for Objects
                   and Microarchitectures for Java

                     In conjunction with ICCD '99

                        Oct 10, Austin, Texas

Most modern programming languages and techniques include
object-oriented methods.  However, mainstream computer architectures
have not acknowledged the presence of objects.  With the widespread
use of object-oriented programming languages and techniques, it is
becoming important for computer architects to acknowledge the
existence of these methods and their impacts on execution (including
high object allocation rates, the impact of garbage collection,
dynamic binding of calls to methods, and dynamic assembly of programs
at run time from components obtained from disparate sources).

Java is an exciting new object-oriented technology.  Hardware for
supporting objects and other features of Java such as multithreading,
dynamic linking and loading is the focus of this workshop.  The impact
of Java's features on micro-architectural resources and issues in the
design of Java-specific architectures are interesting topics that
require immediate attention of the research community.

The purpose of this workshop is to draw together researchers and
practitioners concerned with hardware support for objects and Java
implementations for a stimulating exchange of views.  To the
organizers' best knowledge, this is the first event of its kind, and
as such is an attempt to begin the task of building a community in
this field.
Topics of interest include (but are not limited to):
 - Microarchitectural features for object-oriented systems, especially
   their quantitative evaluation
 - Measurements of hardware-level behavior of object-oriented systems
 - Design of Java Processors: resource, power and performance constraints
 - Tuning Java compilers and applications to efficiently utilize hardware 
 - Memory hierarchy for supporting objects
 - Instruction set designs and enhancements to support objects and 
   Java execution.  

The format of the workshop will include presentations of selected
papers and plenty of time for discussion. There will be a special
panel session on 

"How can hardware support Java Virtual Machine Implementations"
