Skeduleringsalgoritmer

Formålet med skedulering Operativsystemer kan bruke forskjellige teknikker for å skedulere en mengde arbeidsoppgaver i form av tråder og prosesser,  med en begrenset mengde ressurser (CPU). Du har en PC med en Intel i7 prosessor (CPU) og kan velge mellom en rekke forskjellige operativsystemer som bruker forskjellige skeduleringsalgoritmer. Hvilken skeduleringsalgoritmer er best?. Det avhenger først … Read more

CPU the easy way – Part 4 (Von Neumann bottleneck)

In the last three posts in this series we have covered the Arithmetic/Logic Unit (ALU), the Control Unit, memory and bus. So far we have seen that the Von Neumann architecture is working very well by transferring instructions and data back and forth between memory and CPU via a bus. So what is this Von … Read more

CPU the easy way – Part 1 (Von Neumann architecture)

Ok, so you have just started studying Computer Science or a similar study and you are now learning about Von Neumann architecture. You might be asking yourself “Why do we care about this in year 2015?” Well, trust me, you do care. The details about the architecture is very well documented and you find dozens … Read more
