Teletypewriter Communication Codes
Teletypewriter Communication Codes Gil Smith [email protected] 2001 (Document Notes) Abstract Preliminary -- 5/01 gil smith Corrections or comments to [email protected] This information is pulled from a variety of sources, such as various emails of the greenkeys group. For more discussion of teletypewriter code development, see: http://www.nadcomm.com/fiveunit/fiveunits.htm http://fido.wps.com/texts/codes/index.html http://www.science.uva.nl/faculteit/museum/DWcodes.html FIVE-UNIT CODES: USTTY and ITA2 (aka BAUDOT) There were a few variations in character codes for five-level teletypewriter machines. The two most-common character codes were ITA2 and USTTY (a variation of ITA2). The USTTY and ITA2 5-level teletypewriter codes are commonly referred to as "Baudot" codes. While this is technically incorrect, these popular 5-level codes evolved from the work of Jean Maurice Emile Baudot of France - - it seems fitting to accept the defacto reference to "Baudot" as implying USTTY or ITA2 codes, since they were the 5-level codes that saw practical use in teletypewriter systems. However, the true Baudot code dates to around 1874, when Baudot designed the "Baudot Multiplex System," a printing telegraph. The system used a 5-level code generated by a device with five keys, operated with two left-hand fingers, and three right-hand fingers -- this required great skill on the part of the operator who entered the code directly. However, it was still a major improvement in communications -- prior to Baudot's design, communication was carried out using Morse code with a telegraph key. The 5-level "Baudot" code was actually designed by Johann Gauss and Wilhelm Weber. -
Digital Radio Technology and Applications
it DIGITAL RADIO TECHNOLOGY AND APPLICATIONS Proceedings of an International Workshop organized by the International Development Research Centre, Volunteers in Technical Assistance, and United Nations University, held in Nairobi, Kenya, 24-26 August 1992 Edited by Harun Baiya (VITA, Kenya) David Balson (IDRC, Canada) Gary Garriott (VITA, USA) 1 1 X 1594 F SN % , IleCl- -.01 INTERNATIONAL DEVELOPMENT RESEARCH CENTRE Ottawa Cairo Dakar Johannesburg Montevideo Nairobi New Delhi 0 Singapore 141 V /IL s 0 /'A- 0 . Preface The International Workshop on Digital Radio Technology and Applications was a milestone event. For the first time, it brought together many of those using low-cost radio systems for development and humanitarian-based computer communications in Africa and Asia, in both terrestrial and satellite environments. Ten years ago the prospect of seeing all these people in one place to share their experiences was only a far-off dream. At that time no one really had a clue whether there would be interest, funding and expertise available to exploit these technologies for relief and development applications. VITA and IDRC are pleased to have been involved in various capacities in these efforts right from the beginning. As mentioned in VITA's welcome at the Workshop, we can all be proud to have participated in a pioneering effort to bring the benefits of modern information and communications technology to those that most need and deserve it. But now the Workshop is history. We hope that the next ten years will take these technologies beyond the realm of experimentation and demonstration into the mainstream of development strategies and programs. -

It runs under OS/360 MVT that supports multiple application program interaction with operators of CRT (cathode ray tube) display stations and of .a teletype. Key. design features discussed include:1) an interface. allowing application programs to be coded in either PL/I or assembler language; 2) use of the teletype for:subsystem control and diagnostic purposes; and 3)a novel interregional conduit allowing an application program running under the Chapel Hill Alphanumeric Terminal (CHAT)_: monitor to interact--like a terminal operator--with a conversational language processor in another region of the OS/360 installation.

Assessment of Data Rates on the Internal and External Cpu Interfaces and Its Applications for Wireless Network-On-Chip Development
MARIIA KOMAR ASSESSMENT OF DATA RATES ON THE INTERNAL AND EXTERNAL CPU INTERFACES AND ITS APPLICATIONS FOR WIRELESS NETWORK-ON-CHIP DEVELOPMENT Master of Science thesis Examiner: Prof. Yevgeni Koucheryavy, Dr. Dmitri Moltchanov Examiner and topic approved by the Faculty Council of the Faculty of Computing and Electrical Engineering on 27th September 2017 I ABSTRACT MARIIA KOMAR: Assessment of data rates on the internal and external CPU interfaces and its applications for Wireless Network-on-Chip development Tampere University of Technology Master of Science thesis, 56 pages November 2017 Master's Degree Programme in Information Technology Major: Information Technology Examiner: Prof. Yevgeni Koucheryavy, Dr. Dmitri Moltchanov Keywords: central processing unit, CPU, CPU performance, Wireless Networks-on-Chip, WNoC, data rates assessment Nowadays central processing units (CPUs) are the major part of the personal com- puters, and usually their progress denes personal computers (PCs) progress. How- ever, modern CPU architecture has a set of limitations mentioned in this thesis. As a result, new CPU architectures are now under development. Most prospective solution in this eld are based on a proposed concept of Wireless Networks-on-Chip (WNoCs), where part of wired connections is changed into wireless links. However in order to design and develop this kind of system, information about data rates on the internal and external CPU interfaces of modern CPUs is needed. Main goals set in the beginning of working on this thesis were to get this data rates assessment and give an assessment of suitable wireless technologies for milticore CPUs with dierent number of cores. In this thesis CPU evolution is described and peculiarities of modern CPU archi- tectures are mentioned.
