FFT Demo Design Of Parallel Optical Interconnection On Chips

In recent years, with the density of VLSIC (Very Large Scaled Integrated Circuit) higher and higher, the demand on the transmission bandwidth is increasingly fastly. Limited by the limited bandwidth, the parallel crosstalk, high power consumption and other insurmountable weaknesses, the traditional electrical interconnection has been difficult to meet this growing demand. In contrary Optical interconnection with high-bandwidth, no crosstalk, low loss and other advantages will probably replace the electrical interconnection in the area of communication of high-density chip interconnection. Therefore, the chip-to-chip optical interconnection has become increasingly more favored by the industry and become the hot spot of development, in recent years.This paper mainly studies the transmission performance of optical interconnection and electrical interconnection. Based on 4-Channel parallel optical transportation platform, we develop the demonstration and verification platform to quantitative compare the transmission capacity of optical interconnection and electrical interconnection. Bearing 16-point and 32-point large-scale FFT parallel computing, the platform can demonstrate the transmission capacity of optical interconnection and electrical interconnection through experiments. From the simulation analysis and experimental demonstration, this paper verifies the superiority of optical interconnection compared to electrical interconnection. In addition, we have made further research about optical Network-on-Chip, two kinds of novel swithing unit of optical Network-on-Chip based on micro-resonator are designed and constructed. Compared with other switching unit of current mainstream research, these switching units can respectively reduce at least 12% and 32% of the key components micro-resonator, so it can effectively reduce the size and lower power consumption. This paper is divided into five chapters.In the first chapter, this paper has investigated and analyzed the current parallel optical interconnection researching background and situation, domestic and international research development. Chapter 2 introduces the ideas of the design, the design process and final solution. In the following chapter 3, this paper focuses on the parallel FFT demonstration design and the results of experiment and simulation of the whole case and makes a detailed description and analysis. In chapter 4, we study the theory of optical interconnection and discuss the design of switching unit of optical Network-on-Chip based on micro-resonator. Finally in Chapter 5, the whole paper is summarized.
