Professor Krste
Asanovic moved from MIT to join the EECS faculty at UC Berkeley in
Summer 2007, and has started a new Architecture Group at ICSI. The
major focus of the group is the realization of efficient parallel
programmable architectures exploiting advances in circuit and device
technologies. The group works closely with the ParLab at UC Berkeley,
developing a new parallel software stack, and the RAMP consortium, developing
FPGA-based parallel architecture emulators.
Current Projects:
Monolithic Silicon Photonics for Processor-to-DRAM Interconnects
In a collaboration with the MIT Center
for Integrated Photonic Systems, researchers from the Architecture Group are exploring the use of
silicon photonics for processor-to-memory interconnect. Projected
advances in electrical signaling seem unlikely to fulfill the memory
bandwidth demands of future manycore processor chips. Monolithic
silicon photonics, which integrates optical components with electrical
transistors in a conventional CMOS process, is a promising new
technology that could provide large improvements in achievable
interconnect bandwidth. In a DARPA-funded effort, the ICSI
Architecture Group is exploring possible memory interconnect schemes
to exploit the new photonic device and circuit technology being
developed at MIT.
Maven (Malleable Array of Vector-thread ENgines)
In earlier work at MIT, Professor Asanovic's team developed
the Scale
vector-thread architecture and processor prototype, which combines
data-level and thread-level parallel execution models in a single
unified architecture. Maven is the second-generation vector-thread
architecture, designed to scale up to hundreds of execution lanes, and
with the goal of providing very high throughput at low energy for a
wide variety of parallel applications. Maven is based on a new
compact lane design, which is replicated to yield a "sea-of-lanes"
execution substrate. At run-time, lanes are ganged together to form
variable-sized vector-thread engines, sized to match application
needs.
