Abstract--This paper presents ReMAP, a reconfigurable
architecture geared towards accelerating and parallelizing
applications within a heterogeneous CMP. In ReMAP, threads
share a common reconfigurable fabric that can be configured
for individual thread computation or fine-grained communica-
tion with integrated computation. The architecture supports
both fine-grained point-to-point communication for pipeline
parallelization and fine-grained barrier synchronization.
The combination of communication and configurable com-
putation within ReMAP provides the unique ability to perform
customized computation while data is transferred between
cores, and to execute custom global functions after barrier
synchronization. ReMAP demonstrates significantly higher
performance and energy efficiency compared to hard-wired
communication-only mechanisms, and over what can ideally
