1.1 Flashcards
the three characteristics of cpu performance
core count, clock speed, cache amount
what does higher core count do
processing multiple instructions simultaneously
what does clock speed increase
more cycles per second (the speed at which data from ram goes to cache)
what does cache amount change
the amount of data and instructions that can quickly be accessed frequently
what happens if clock speed is too high
there is a risk of overheating and damaging the cpu (system failure)
how do you know which instruction is next
program counter PC
how do you know which bit of ram a process is using
memory address register
how do you know the value stored in ram
memory data register
how do you know which instruction is being processed
current instruction register
how do you store the results of any process
accumulator acc
what is a cycle
fetch, decode, execute
the architecture all processors are based on
von neumann architecture
what is a register
a part of the cpu used as a storage location
