  • Making the Switch to Rapidio

Leroux Technology Analyst QNX Software Systems Ltd. [email protected] Introduction Manufacturers of networking equipment have hit a bottleneck. On the one hand, they can now move traffic from one network element to another at phenomenal speeds, using line cards that transmit data at 10 Gigabits per second or higher. But, once inside the box, data moves between boards, processors, and peripherals at a much slower clip: typically a few hundred megabits per second. To break this bottleneck, equipment manufacturers are seeking a new, high-speed — and broadly supported — interconnect. In fact, many have already set their sights on RapidIO, an open-standard interconnect developed by the RapidIO Trade Association and designed for both chip-to-chip and board-to-board communications. Why RapidIO? Because it offers low latency and extremely high bandwidth, as well as a low pin count and a small silicon footprint — a RapidIO interface can easily fit Making the Switch to RapidIO into the corner of a processor, FPGA, or ASIC. Locked Out by Default: The RapidIO is also transparent to software, allowing Problem with Conventional any type of data protocol to run over the intercon- Software Architectures nect. And, last but not least, RapidIO addresses the demand for reliability by offering built-in While RapidIO provides a hardware bus that is error recovery mechanisms and a point-to-point both fast and reliable, system designers must find or architecture that helps eliminate single points develop software that can fully realize the benefits of failure.

  • Rapidio™: an Embedded System Component Network Architecture
    February 22, 2000 RapidIOª: An Embedded System Component Network Architecture Architecture and Systems Platforms Motorola Semiconductor Product Sector 7700 West Parmer Lane, MS: PL30 Austin, TX 78729 Abstract This paper describes RapidIO, a high performance low pin count packet switched sys- tem level interconnect architecture. The interconnect architecture is intended to be an open standard which addresses the needs of a variety of applications from embedded infrastructure to desktop computing. Applications include interconnecting microproces- sors, memory, and memory mapped I/O devices in networking equipment, storage sub- systems, and general purpose computing platforms. This interconnect is intended primarily as an intra-system interface, allowing chip to chip and board to board com- munications at giga-byte per second performance levels. Supported programming mod- els include globally shared distributed memory and message-passing. In its simplest form, the interface can be implemented in an FPGA end point. The interconnect archi- tecture deÞnes a protocol independent of a physical implementation. The physical fea- tures of an implementation utilizing the interconnect are deÞned by the requirements of the implementation, such as I/O signalling levels, interconnect topology, physical layer protocol, error detection, etc. The interconnect is deÞned as a layered architecture which allows scalability and future enhancements while maintaining compatibility. 1 of 25 Introduction 1 Introduction Computer and embedded system development continues to be burdened by divergent requirements. On one hand the performance must increase at a nearly logarithmic rate, while on the other hand system cost must stay the same or decrease. Several applica- tions, such as those found in telecommunications infrastructure equipment, are also bur- dened with increasing capabilities while decreasing the board size and ultimately the ßoor space which equipment occupies.

  • Analysis and Optimisation of Communication Links for Signal Processing Applications
    Analysis and Optimisation of Communication Links for Signal Processing Applications ANDREAS ÖDLING Examensarbete inom elektronik- och datorsystem, avancerad nivå, 30 hp Degree Project, in Electronic- and Computer Systems, second level School of Information and Communication Technology, ICT Royal Institute of Technology, KTH Supervisor: Johnny Öberg Examiner: Ingo Sander Stockholm, November 12, 2012 TRITA-ICT-EX-2012:287 Abstract There are lots of communication links and standards cur- rently being employed to build systems today. These meth- ods are in many way standardised, but far from everyone of them are. The trick is to select the communication method that best suit your needs. Also there is currently a trend that things have to be cheaper and have shorter time to market. That leads to more Component Off The Shelf (COTS) systems being build using commodity components. As one part of this work, Gigabit Ethernet is evaluated as a COTS-solution to building large, high-end systems. The computers used are running Windows and the pro- tocol used over Ethernet will be both TCP and UDP. In this work an attempt is also made to evaluate one of the non-standard protocols, the Link Port protocol for the TigerSHARC 20X-series, which is a narrow-bus, double- data-rate protocol, able to provide multi-gigabit-per-second performance. The studies have shown lots of interesting things, e.g. that using a standard desktop computer and network card, the theoretical throughput of TCP over Gigabit Ethernet can almost be met, reaching well over 900 Mbps. UDP performance gives on the other hand birth to a series of new questions about how to achieve good performance in a Windows environment, since it is constantly outperformed by the TCP connections.

  • Serial Multiprotocol Transmission with the Latticesc FPGA
    SERIAL MULTI-PROTOCOL TRANSMISSION WITH THE LatticeSC FPGA A Lattice Semiconductor White Paper February 2006 Lattice Semiconductor 5555 Northeast Moore Ct. Hillsboro, Oregon 97124 USA Telephone: (503) 268-8000 www.latticesemi.com 1 Serial Multi-Protocol Transmission with the LatticeSC FPGA A Lattice Semiconductor White Paper Introduction The movement towards serial chip to chip and backplane interconnects continues at a frantic pace, particularly in the communications and storage arena. Standardization forums such as the OIF, RapidIO TA, PCI-SIG, OBSAI and CPRI have solidified their work and various packet-based protocols are in the process of being adopted by system and chip vendors. In addition to these emerging protocols, there is also a broad installed base of more mature serial-based protocols such as GbE, 10G Ethernet, SONET and Fibre Channel that must be addressed as they undergo a facelift to accommodate the multi-protocol nature of the network. As the PHY and protocol layers of these new standards are being established and work continues to upgrade existing technology in the field, system vendors now have to decide how best to transmit these various protocols over existing transmission infrastructures, both inter- and intra-board. Although each protocol is unique, one thing that they all have in common is a layered protocol stack. However, all protocol stacks are not created equal: their implementation can vary greatly from one layer to the next. Typically, the physical layer consists of fixed functionality that is common to multiple packet-based protocols, while the upper layers tend to be more customizable. The dynamic of upper layer functionality is necessitated by both the natural evolution that takes place when dealing with an emerging standard as well as the desire of system vendors to create their own “value add” via proprietary functionality.

U prvom poglavlju data je opšta podela magistrala, ukratko je opisan njihov način funkcionisanja, dati su odgovarajući standardi, generacije, a ukratko su opisane i suerbrze magistrale. U drugom poglavlju dat je alfabetni spisak portova, od kojih je većina obuhvaćena ovim radom. Treće poglavlje odnosi se na portove personalnih računara, kako Pentium tako i Apple i Mackintosh. Četvrti deo odnosi se na opisane portove i interfejse i njihovo međusobno poređenje. U ovom poglavlju date su i detaljne tabele u kojima su navedene i opisane neke od najvažnijih funkcija. I konačno, peto poglavlje se odnosi na hardver – USB portove, memorijske kartice SCSI portove. U Nišu, 03.10.2008. godine 3 1. Magistrale Prilagodljivost personalnog računara - njegova sposobnost da se proširi pomoću više vrsta interfejsa dozvoljavajući priključivanje mnogo različitih klasa dodatnih sastavnih delova i periferijskih uredjaja - bila je jedan od ključnnih razloga njegovog uspeha. U suštini, moderni PC računarski sistem malo se razlikuje od originalne IBM konstrukcije - to je skup komponenata, kako unutrašnjih tako i spoljašnjih, medjusobno povezanih pomoću elektronskih magistrala, preko kojih podaci putuju, dok se obavlja ciklus obrade koji ih pretvara od podataka ulaza u podatke izlaza.
