In this paper, we describe the design flow, architecture and implementation of our 3D multiprocessor with NoC. The design based on 16 processors communicating using a 4x2x2 mesh NoC spread on two tiers is discussed in detail and will be fabricated using Tezzaron technology with 130 nm Global Foundaries low power standard library. The purpose of this work is to accurately measure NoC performances in real 3D chip when running mobile multimedia applications to evaluate the impact of 3D architecture compared to 2D.

This paper discusses the relative merits of the various digital signal processing techniques used to channelise signals. ChannelCore Flex (CCF) exploits all of these strengths to provide a flexible channeliser architecture that is capable of supporting thousands of independently defined channels in a single FPGA. The CCF core can be tailored at build-time to support the user’s generic channel plan and required level of flexibility. The precise channel plan can then be loaded and updated at run-time. The FPGA resources required to implement CCF in a Xilinx Spartan-6 LX100 are presented for an example channel plan with 1024 channels of various bandwidths.

This paper presents a digital design flow in order to design high performance differential Emitter Coupled Logic (ECL) circuits efficiently. The proposed flow is similar to the ordinary digital CMOS Design Flow. It uses standard design tools for gate-level synthesis and layout generation. The differential logic synthesis is separated in two phases. Starting from a synthesized, single-ended HDL design description, a fully differential ECL netlist is generated using a Verilog netlist converter before the layout phase. This results in a short development time and fast verification possibilities. Furthermore, the layout generation can be done in one shot together with digital CMOS components.
