Network-on-Chip (NoC) has been proposed as a solution for the communication challenges of Multi-ProcessorSystem-on-chip (MPSoC) design in nanoscale technologies and it has better reusability and scalability. However along with the advantages of any communication parameter follow its disadvantages. Most state-of-the-art NoC architecture and their design flows is optimized for a single application, and no single NoC can provide optimal performance across a wide range of applications. In this research, a reconfigurable and adaptable Network-on-Chip architecture is proposed. Adaptive routing components are designed to enable the router to select a path with less congestion. Parameterize file is designed to enable the NoC to be reconfigured and scalable.

Abstract-XY adaptive routing protocol is a routing protocol used on UTAR NoC communication architecture. This routing algorithm adapts shortestpath first algorithm, which it will not able to work optimally if the closest route have no longer enough bandwidth to continue the packet.The router will store Packet inside and forwarded to the nearest router when closest route has enough bandwidth. This paper suggests TTL based routing algorithm to resolve this issue. TTL based routing algorithm adapts XY adaptive routing protocol by adding several limits on RTL UTAR NoC and added bit in each packet sent by router. TTL based algorithm used more bit and parameters in choosing alternative routes inside the communication architecture. Use of TTL on TTL based routing different from use TTL on communication network. Packets that carry TTL value that equal to Maximum TTL will be route using XY adaptive routing protocol. TTL based routing algorithm has shown better performance compared to XY adaptive routing on some of the experiment done using MSCL NoC Traffic Pattern Suite. This research also proves that TTL based routing algorithm cannot work optimally on smallscaled architecture.

Abstrak-Jaringan wireless LAN banyak digunakan dalam perkantoran yang memberikan keuntungan seperti Samba Server, Printer, Squid Server, dan Torrent Client. Namun pada umumnya dibutuhkan paling tidak sebuah komputer untuk menjalankan layanan-layanan tersebut. Dalam jaringan wireless LAN dibutuhkan perangkat wireless router yang dilengkapi dengan firmware agar bisa berjalan dengan baik. Firmware DD-WRT dinyatakan sebagai firmware open source yang memberikan keleluasaan kepada user untuk menambahkan layanan pada sebuah wireless router. Penelitian ini bertujuan untuk mempelajari penambahan layanan pada wireless router berbasis DD-WRT serta menguji kinerja layanan yang ditambahkan tersebut pada wireless router. Hasil pengujian menunjukkan DD-WRT dapat digunakan sebagai firmware alternatif untuk memenuhi kebutuhan layanan pada skala kecil. Namun, penambahan layanan ini harus memperhatikan spesifikasi wireless router.
