Networks-on-Chip is a recent solution paradigm adopted to increase the performance of multi-core designs. The key idea is to interconnect various computation modules (IP cores) in a network fashion and transport packets simultaneously across them, thereby gaining performance. In addition to improving performance by having multiple packets in flight, NoCs also present a host of other advantages including scalability, power efficiency, and component re-use through modular design. This work focuses on design and development of high performance communication architectures for FPGAs using NoCs. Once completely developed, the above methodology could be used to augment the current FPGA design flow for implementing multi-core SoC applications. We design and implement an NoC framework for FPGAs, Multi-Clock On-Chip Network for Reconfigurable Systems (MoCReS). We enable the routers to function at independent clock frequencies, that are dictated by the FPGA place and route constraints, and yet follow a low latency virtual cut-through flow control. With increasing design complexities, power trade-offs play a significant role in FPGA design. We analyze the power consumed in the NoC framework that we have developed on a Virtex-4 FPGA. Through experimental results, we study the various components of power consumed in an FPGA based NoC. We propose a novel micro-architecture for a hybrid two-layer router that supports both packet-switched communications, across its local and directional ports, as well as, time multiplexed circuit-switched communications among the multiple IP cores directly connected to it. Results from place and route VHDL models of the advanced router architecture show an average improvement of 20.4% in NoC bandwidth (maximum of 24% compared to a traditional NoC). We parameterize the hybrid router model over the number of ports, channel width and bRAM depth and develop a library of network components (MoClib Library). Synthesizing an NoC topology for FPGAs from the above library of network components requires a complex trade-off among switch complexity, area available and bandwidth capacity. We develop an algorithm and an application-generic design flow that includes required bandwidth and area in the cost function and synthesizes the NoC topology for FPGAs. For a set of real application and synthetic benchmarks, our approach shows an average reduction of 21.6% in FPGA area (maximum of 26%) for equivalent bandwidth constraints when compared with a baseline approach. Interconnecting IP cores along with our NoC requires a glue logic that can connect different versions of the router to IPs. To accomplish this, we design a customizable Network Interface that is compatible with our 2-layer hybrid router. Towards capturing real core implementation effects, we characterize a library of soft IP cores and implement a typical image compression application on our FPGA. Through experiments we determine the area and power overhead of our on-chip network on an FPGA when implemented along with a typical application. Further by accurately modeling our On-chip network for area, delay and power, we develop a platform that could be used to floorplan a complete multi-processor application along with the NoC.

Packet processing is the enabling technology of networked information systems such as the Internet and is usually performed with fixed-function custom-made ASIC chips. As communication protocols evolve rapidly, there is increasing interest in adapting features of the processing over time and, since software is the preferred way of expressing complex computation, we are interested in finding a platform to execute packet processing software with the best possible throughput. Because FPGAs are widely used in network equipment and they can implement processors, we are motivated to investigate executing software directly on the FPGAs. Off-the-shelf soft processors on FPGA fabric are currently geared towards performing embedded sequential tasks and, in contrast, network processing is most often inherently parallel between packet flows, if not between each individual packet.Our goal is to allow multiple threads of execution in an FPGA to reach a higher aggregate throughput than commercially available shared-memory soft multi-processors via improvements to the underlying soft processor architecture. We study a number of processor pipeline organizations to identify which ones can scale to a larger number of execution threads and find that tuning multithreaded pipelines can provide compact cores with high throughput. We then perform a design space exploration of multicore soft systems, compare single-threaded and multithreaded designs to identify scalability limits and develop processor architectures allowing threads to execute with as little architectural stalls as possible: in particular with instruction replay and static hazard detection mechanisms. To further reduce the wait times, we allow threads to speculatively execute by leveraging transactional memory. Our multithreaded multiprocessor along with our compilation and simulation framework makes the FPGA easy to use for an average programmer who can write an application as a single thread of computation with coarse-grained synchronization around shared data structures. Comparing with multithreaded processors using lock-based synchronization, we measure up to 57% additional throughput with the use of transactional-memory-based synchronization. Given our applications, gigabit interfaces and 125 MHz system clock rate, our results suggest that soft processors can process packets in software at high throughput and low latency, while capitalizing on the FPGAs already available in network equipment.
