The focus of effort in the ITER Engineering Design Activities (EDA) since 1998 has been the development of a new design to meet revised technical objectives and a cost reduction target of about 50% of the previously accepted cost estimate. Drawing on the design solutions already developed and using the latest physics results and outputs from technology R&D… (More)
To design a new processor or to modify an existing one, designers need to gather data to estimate the influence of specific architecture features on the performance of the <i>proposed machine</i> (PM). To obtain this data, it is necessary to measure on an <i>existing machine</i> (EM) the dynamic behavior of <i>typical programs</i>. Traditionally,… (More)
The use of registers in a processor reduces the data and instruction memory traffic. Since this reduction is a significant factor in the improvement of the program execution time, recent VLSI processors have a large number of registers which can be used efficiently because of the advances in compiler technology. However, since registers have to be… (More)
This work discusses the protection of the Processor Status Word of the PDP-11/60 computer and shows how a non-privileged user can modify the processor priority and execute his programs at PR7 priority level, that is, with all interrupts blocked. It also suggests some possible solutions to this problem. Finally, it considers how the problem is solved in the… (More)
