Betalkort : Slutrapport
- 1980
-
Reports (other academic/artistic)abstract
- Idén till Universalkort uppkom för cirka tre år sedan, som en följd av ett examensarbete med namnet "ID- kort med minne". Där undersöktes möjligheten att placera ett nonvolatilt minne på ett kort. Fortsättningen på det projektet beskrivs kort under rubriken ”Existerande hårdvarusystem”.Utvecklingen av Betal- och Universalkortsidén har sedan dess bedrivits i samarbete med personal på Institutionen för Systemteknik inom ämnesområdet informationsteori vid LiTH. Jag vill rikta ett varmt tack till dessa och speciellt till Rolf Blom , Robert Forchheimer och Ingemar Ingemarsson för deras bidrag till arbetet.

Automatic computer code generation for hyperbolic and parabolic differential equations
- 1980
-
In: SIAM JOURNAL ON SCIENTIFIC AND STATISTICAL COMPUTING. - : Society for Industrial & Applied Mathematics (SIAM). - 0196-5204 .- 2168-3417. ; 1:2, s. 249-259
-
Journal article (peer-reviewed)abstract
- A program system which generates computer code for the numerical solution of systems of hyperbolic and parabolic differential equations is described. The input to the program is a mathematical formulation of a hyperbolic or parabolic initial boundary value problem in one space dimension. The differential equations and boundary conditions are analyzed by the program system, and a finite difference algorithm is designed for the given problem. The output is an executable FORTRAN program.

CAD & VLSI Course in Linköping, 1981
- 1981
-
Reports (other academic/artistic)abstract
- On July 6 - 11, 1981, the LSI Design Center and the DIGSIM team at Linköping Institute of Technology arranged a CAD & VLSI Course. 60% of the 75 attendants represented different European industries. The aim of the course was to present current and future directions in techniques, methods and CAD-tools for development of LSI and VLSI designs. 6 of the 11 lecturers represented industries as IBM, WANG, DEC, ASEA-HAFO and Electric Bureau. The course attendants had access to DEC-10 and· VAX-11 / 78 computers from graphic terminals. Among the offered software packages were CIFPLOT, DIGSIM, GAELIC, ISPS, NAP2, SPICE and CALMOS.

En studie av kryptering vid satellitkommunikation
- 1982
-
Reports (other academic/artistic)abstract
- Stormakterna övervakar varandra och den övriga världen med hjälp av ett stort antal spionsatelliter. Det finns många olika typer av rent militära satelliter, men även alla . .normalt civila satelliter som lämnar information som kan vara av taktisk eller strategisk betydelse och måste betraktas som militära i en konfliktsituation. Som exempel på dessa "halvmilitära" satelliter kan nämnas; vädersatelliter, telesatelliter, navigationssatelliter och fjärranalyserande satelliter typ LANDSAT….

Linear Codes for Real-Time Colour Graphics
- 1980
-
Reports (other academic/artistic)abstract
- In this paper, the problem of 'hidden - surface' elimination is considered. It is shown that a new linear surface- filling algorithm leads to some simple techniques for hidden-surface removal. Necessary conditions are established for three such methods to work and hard ware to implement these solutions is shown to be practicable. Each of the three proposed methods is seen to have advantages in certain circumstances - the choice between them depends very much on the nature of the graphics system in which they might be used.

Picture Coding wiht the General Operator Processor (GOP)
- 1980
-
Reports (other academic/artistic)abstract
- Basically, this report gives guidelines for picture coding within the framework of GOP. Two general methods are suggested, exploiting the structures of this general, versatile and elegant operator. The first one is based on the convolutional aspects (sub band coding) whereas the second uses contour and texture description. Alternatives of these two techniques are also indicated. Because GOP has close similarities with the human visual system, super compression in picture coding can be expected. Obtainable efficiencies are indicated in a rather speculative way.

Hierarkisk kodning för faksimilbilder
- 1980
-
Reports (other academic/artistic)abstract
- Här undersöks hierarkisk kodning av binära bilder och jämförs med en av CCITT standardiserad endimensionell kod. Resultaten visar att prestanda för de hierarkiska koderna uppfyller det mål man vanligtvis vill uppnå.

Micro- and System Architectures in the 1980's
- 1980
-
Reports (other academic/artistic)abstract
- After approxirnate1y 30 years experience with microprogrammed control concepts, we find ourselves at an interesting turning point leading into the 1980's. Experience with various microprogrammed contro1 techniques has been obtained, some experience has been obtained in recent years in the redistribution of functions between various software and microarchitectureal levels and we have a better idea of methods of timing and synchronization. This know1ed~e together with the possibilities brought on by VLSI will meet in the 1980's and have several interesting effects upon system architecture at microarchitecture and higher architectural levels.We shall consider some of the opportunities and limitations of VLSI and their potential effects upon microarchitecture followed by a view of the future utilization of "programmed logic". More specifically, we shall be considering the structuring of logic, synchronization, microarchitecture characteristics, target machine properties and special purpose microprogrammed machines. Further, we shall touch upon relationships to function distribution, computer aided design and the possibilities for architectural synthesis.
