IntroductionIntroduction In Part A of our project we established a In Part A of our project we established a

line of communication between a PC and line of communication between a PC and our Nios II system, at a speed of 100 Mbps, our Nios II system, at a speed of 100 Mbps, Full duplex.Full duplex.

Now we will establish a “smart” line of Now we will establish a “smart” line of communication, between multiple Nios II communication, between multiple Nios II systems and multiple PCs.systems and multiple PCs.

Project AimProject Aim We will implement the “smart” We will implement the “smart”

communication between N generators of communication between N generators of nios II systems and M processing units of nios II systems and M processing units of PCs.PCs.

We will implement the concept We will implement the concept mentioned above when N=2, M=2. We mentioned above when N=2, M=2. We will create a network which consists of 2 will create a network which consists of 2 PCs and 2 Nios II systems which are able PCs and 2 Nios II systems which are able to process packages in T time and are to process packages in T time and are managed by a management unit.managed by a management unit.

Concept - Concept - Centralized Centralized management unitmanagement unit

Our project will include a management unit which will manage the flow of packages from the systems to the processing units so that the bottleneck phenomena will be lessened.

Our Implementation…

Our project requires us to create a management unit which communicates using LAN.

We will create a generic managing unit that can be used on any platform

However, we will use the PC as a platform. The advantages to our choice are that it’s low cost, easy to manage and maintain.

The Processing Units and Nios II Systems will send a connection request to the Managing Unit using port 10000. The request will

include their Ip address. The only purpose of port 10000 will be to listen to connection requests.

The Managing Unit will hand out an ID to each computer and system as well as the port number in which the managing system will use to communicate with all systems (10001 for Nios II, 10002

for Processor) . The Computer’s Id will correspond with the port number in which the Nios II System will use to send a package to

that specific computer.

The System Units will then begin to send requests for processing packages to the Managing Unit (the requests will be stored in a queue). The Managing Unit will respond with the port number of

the available Processing Unit and the System will send the package accordingly.
