Abstract
This document briefly characterizes the communication media used in multiprocessed architectures. The main objective of this characterization is to show a new communication model based on packet switching called Networks-On-Chip (NoC). This publication shows a network architecture called NoC Hermes, which was interconnected to a Multiprocessor-Systems-on-Chip (MPSoC) composed of four MicroBlaze processors. This connection was made thanks to the design and development of a Network Interface generated in VHDL code. The MicroBlaze processors could interact with the Hermes Switches through the Network Interface to create a multiprocessor architecture interconnected by a NoC. Another architecture of multiprocessors interconnected by buses was also created to make comparisons. A steganography application was developed for both architectures, in which two processors are multiprocessed and work simultaneously. Unfortunately, in this application, measuring the latency and energy consumption directly was impossible, so simulators were used to estimate these measurements.
