Network-on-Chip (NoC) is the most advanced technology to address the communication bottleneck of System-on-Chip (SoC). Routing algorithms using wormhole packet switching is best for NoC as it provides high throughput, low latency and requires small buffers. But it can cause deadlock during the system operation. Ensuring deadlock-free operation of NoC is a major challenge. This paper presents a combined method to make the network routing-dependent deadlock-free by using hold-release tagging method and message-dependent deadlock-free by adding virtual channels. This uses wormhole switching and supports adaptive and multicast routing. The data body flits of multicast packets will follow the same path made by the multicast headers which are sending in advance. An additional Identification (ID) field is packetized together with the flits belongs to the same packet. These methods are supported by the NoC router which controls the deadlock in tree-based multicast routing.

Like democratic equality where everyone has the right to participate and exercise freedom to enjoy the resources of the nation, digital equality is the urge of modern times to acquaint the prospective nationals to enjoy the internet services at ease and access. There are a lot of bottlenecks on the way of obtaining an approach by every person to the benefits of internet. These are due several economic, social, gender based, demographic, psychological or personal reasons for being unable to achieve digital equality. For example, disabled persons have insufficient scope for use and possession of internet services. Intelligent Communities promote digital equity because it is the moral thing to do. They also do it for eminently practical reasons. The use of ICT is the need of hour for coming at par with the international challenges of progress and standards and more important is its use by every person of a nation. World is facing digital divide at the very outset ever since the world has witnessed the digital progress and advancement. This digital divide has to be shortened to minimum by employing necessary efforts to bring together the haves and have nots.

I have designed a Real-Time Co-Operating System (RTCS) for simultaneously supporting real-time and non-real-time activities on a workstation with two or more processors. The RTCS is the software equivalent of a co-processor, with software architecture analogous to the hardware architecture that has been used in many workstations and personal computers. In this paper, I discuss a software prototype of the RTCS, which co-exists with Solaris 7 on a four-processor Sun SPARC 20. I summarize the feasibility of the approach through an experimental characterization of Solaris 7. I address the various technical issues involved and present the details of my design. The RTCS is targeted towards real-time applications in the signal processing, sensor- based control, process control, multimedia, and manufacturing domains.
