“…The advantages of deterministic routing are many, simple design and analysis, ease of implementation, low latency for well behaved loads, etc. Likewise, wormhole flow control dominates the NoC architectures [24], [26]- [28]. Flitbased flow control schemes, such as wormhole, are popular because they provides a level of data management that is ideal for the kind of transfers and resource constrains commonly found in today's NoC.…”

System-level design (SLD) provides a solution to the challenge of increasing design complexity and time-to-market pressure in modern embedded system designs. In this paper, we propose a novel system-level approach to communication architecture modeling, which was not yet well addressed in existing SLD methodologies. In particular, we show how to develop statistical models for communication architectures. These new models are capable of capturing communication details at higher abstraction levels than previously possible. We demonstrate how to use the mean-square-error as a tool for developing these models, and show where to integrate these models in the design process.

“…A tree-based routing algorithm which has hardware support for multicast (VCTM) was presented in [12]. Similar to [11], VCTM used ID-tag-based Multicast routing named virtual circuit table (VCT). It constructs the multicast tree incrementally by sending a unicast packet to each destination node.…”

“…For the reason that they used just one setup packet to build the whole path, the latency of the setup is long [10]. An ID-tag-based multicast routing is proposed in [11]. In this paper, a flexible mechanism to manage broadcast-flow to share the communication link in NoCs is presented.…”

In this paper, a novel hardware support for multicast on mesh Networks-on-Chip (NoC) is proposed. It supports multicast routing on any shape of tree-based paths. Two powerefficient tree-based multicast routing algorithms, Optimized tree (OPT) and Left-XY-Right-Optimized tree (LXYROPT) are also proposed. XY tree-based (XYT) algorithm and multiple unicast copies (MUC) are also implemented on the router as baselines. Along with the increase of the destination size, compared with MUC, OPT and LXYROPT achieve a remarkable improvement in both latency and throughput while the average power consumption is reduced by 50% and 45%, respectively. Compared with XYT, OPT is 10% higher in latency but gains 17% saving in power consumption. LXYROPT is 3% lower in latency and 8% lower in power consumption. In some cases, OPT and LXYROPT give power saving up to 70% less than the XYT.

“…Performing a multicast operation in all approaches mentioned above requires setting up a connection explicitly or implicitly before the transmission starts. In XHiNoC (Samman et al, 2008) the detailed implementation of a wormhole router offering multicast communication service is presented. The XHiNoC router transfers a flit to its all destinations in parallel.…”
