On-Chip Interconnect Schemes for Reconfigurable System-On-Chip
On-chip Interconnect Schemes for Reconfigurable System-on-Chip Andy S. Lee, Neil W. Bergmann. School of ITEE, The University of Queensland, Brisbane Australia {andy, n.bergmann} @itee.uq.edu.au ABSTRACT On-chip communication architectures can have a great influence on the speed and area of System-on-Chip designs, and this influence is expected to be even more pronounced on reconfigurable System-on-Chip (rSoC) designs. To date, little research has been conducted on the performance implications of different on-chip communication architectures for rSoC designs. This paper motivates the need for such research and analyses current and proposed interconnect technologies for rSoC design. The paper also describes work in progress on implementation of a simple serial bus and a packet-switched network, as well as a methodology for quantitatively evaluating the performance of these interconnection structures in comparison to conventional buses. Keywords: FPGAs, Reconfigurable Logic, System-on-Chip 1. INTRODUCTION System-on-chip (SoC) technology has evolved as the predominant circuit design methodology for custom ASICs. SoC technology moves design from the circuit level to the system level, concentrating on the selection of appropriate pre-designed IP Blocks, and their interconnection into a complete system. However, modern ASIC design and fabrication are expensive. Design tools may cost many hundreds of thousands of dollars, while tooling and mask costs for large SoC designs now approach $1million. For low volume applications, and especially for research and development projects in universities, reconfigurable System-on-Chip (rSoC) technology is more cost effective. Like conventional SoC design, rSoC involves the assembly of predefined IP blocks (such as processors and peripherals) and their interconnection. -

Wishbone Bus Architecture – a Survey and Comparison
International Journal of VLSI design & Communication Systems (VLSICS) Vol.3, No.2, April 2012 WISHBONE BUS ARCHITECTURE – A SURVEY AND COMPARISON Mohandeep Sharma 1 and Dilip Kumar 2 1Department of VLSI Design, Center for Development of Advanced Computing, Mohali, India [email protected] 2ACS - Division, Center for Development of Advanced Computing, Mohali, India [email protected] ABSTRACT The performance of an on-chip interconnection architecture used for communication between IP cores depends on the efficiency of its bus architecture. Any bus architecture having advantages of faster bus clock speed, extra data transfer cycle, improved bus width and throughput is highly desirable for a low cost, reduced time-to-market and efficient System-on-Chip (SoC). This paper presents a survey of WISHBONE bus architecture and its comparison with three other on-chip bus architectures viz. Advanced Microcontroller Bus Architecture (AMBA) by ARM, CoreConnect by IBM and Avalon by Altera. The WISHBONE Bus Architecture by Silicore Corporation appears to be gaining an upper edge over the other three bus architecture types because of its special performance parameters like the use of flexible arbitration scheme and additional data transfer cycle (Read-Modify-Write cycle). Moreover, its IP Cores are available free for use requiring neither any registration nor any agreement or license. KEYWORDS SoC buses, WISHBONE Bus, WISHBONE Interface 1. INTRODUCTION The introduction and advancement of multimillion-gate chips technology with new levels of integration in the form of the system-on-chip (SoC) design has brought a revolution in the modern electronics industry. With the evolution of shrinking process technologies and increasing design sizes [1], manufacturers are integrating increasing numbers of components on a chip. -

This technology promises new levels of integration on a single chip, called the system-on-a-chip (SoC) design, but also presents significant challenges to the chip designers. Processing cores on a single chip may number well into the high tens within the next decade, given the current rate of advancements [1]. Interconnection networks in such an environment are, therefore, becoming more and more important [2]. Currently, on-chip interconnection networks are mostly implemented using buses. For SoC applications, design reuse becomes easier if standard internal connection buses are used for interconnecting components of the design. Design teams developing modules intended for future reuse can design interfaces for the standard bus around their particular modules. This allows future designers to slot the reuse module into their new design simply, which is also based around the same standard bus [3]. -

Xilinx XAPP1000: Reference System : Plbv46 PCI Express in a ML555
Application Note: Embedded Processing Reference System: PLBv46 Endpoint Bridge R for PCI Express in a ML555 PCI/PCI Express Development Platform XAPP1000 (v1.0.1) May 6, 2008 Author: Lester Sanders Abstract This reference system demonstrates the functionality of the PLBv46 Endpoint Bridge for PCI Express® used in the Xilinx ML555 PCI/PCI Express Development Platform. The PLBv46 Endpoint Bridge is used in x1 and x4 PCIe® lane configurations. The PLBv46 Endpoint Bridge uses the Xilinx Endpoint core for PCI Express in the Virtex®-5 XC5VLX50T FPGA. The PLBv46 Bus is an IBM CoreConnect bus used for connecting the IBM PPC405 or PPC440 microprocessors, which are implemented as hard blocks on Xilinx Virtex FPGAs, and the Xilinx Microblaze microprocessor to Xilinx IP. A variety of tests generate and analyze PCIe traffic for hardware validation of the PLBv46 Endpoint Bridge. PCIe transactions are generated and analyzed by Catalyst and LeCroy test equipment. For endpoint to root complex transactions, the pcie_dma software application generates DMA transactions which move data over the PCIe link(s). For root complex to endpoint transactions, Catalyst and LeCroy scripts generate PCIe traffic. A Catalyst script which configures the PLBv46 Endpoint Bridge and performs memory write/read transactions is discussed. The steps to use Catalyst to measure PCIe performance are given, and performance results are provided.The principal intent of the performance testing is to illustrate how performance measurements can be done. Two stand-alone tools, PCItree and Memory Endpoint Test, are used to write and read PLBv46 Endpoint Bridge configuration space and memory in a PC environment.
