Considerations for Multiprocessor Topologies *

چکیده
Choosing a multiprocessor interconnection topology may depend on high-level considerations, such as the intended application domain and the expected number of processors. It certainly depends on low-level implementation details, such as packaging and communications protocols. We first use rough measures of cost and performance to characterize several topologies. We then examine how implementation details can affect the realizable performance of a topology.

Routability Prediction of Network Topologies in FPGAs
A fundamental difference between ASICs and FPGAs is that the wires in ASICs are designed to match the requirements of a particular design. Conversely, in an FPGA, area is fixed and routing resources exist whether or not they are used. Modern FPGAs have the logic and routing resources to implement networks of multiprocessor systems, and system-level interconnection becomes a key element of the d...
متن کاملPhysical Planning for On-Chip Multiprocessor Networks and Switch Fabrics
On-chip implementation of multiprocessor systems requires the planarization of the interconnect network onto the silicon floorplan. Manual floorplanning approaches will become increasingly more difficult and ineffective as multiprocessor complexity increases. Compared with traditional ASIC architectures, multiprocessors have homogeneous processing elements and regular network topologies. Theref...
متن کاملEvaluation of memory latency in cluster-based cache- coherent multiprocessor systems with dierent interconnection topologies
This research investigates memory latency of cluster-based cache-coherent multiprocessor systems with dierent interconnection topologies. Each node in a cluster includes a small number of processors and a portion of the shared-memory, which are all connected through a split transaction bus. Each processor has two levels of caches. As the number of processors in a node is small, a snoopy cache ...
متن کاملSelf-Organizing Process Mapping in a Multiprocessor System
In this report we describe a self-organizing map to solve the mapping problem in a multiprocessor system with a distributed memory architecture. Experimental results for 2-dim lattice based processor networks are presented and the generalization of this approach to arbitrary processor topologies is discussed.

On-chip implementationofmultiprocessor systemsneeds toplanarise the interconnect networks onto the silicon floorplan. Compared with traditional ASIC/SoC architectures, Multiprocessor Systems on Chips (MPSoC) node processors are homogeneous, and MPSoC network topologies are regular. Therefore, traditional ASIC floorplanning methodologies that perform macro placement are not suitable for MPSoC de...
