1.1 systems Architecture
factors affecting CPU performance
Cache Size
reduces the waiting time for instructions to be removed by memory
clock speed
frequency of the pulses that synchronizes the system
measured in hertz
faster the clock speed, more processes per second
overclocking can be done to temporarily increase the performance of the CPU
between 3 - 5 hertz
number of cores
each core acts as a processor
more processors means that more FDE cycles can be performed simultaneously
1.3 Embedded systems
not programmable by the user
forms part of a larger system
examples include central heating systems etc.
characteristics of an embedded system
Limited function
cheaper to design and build
tends to require less power
can be coded in the processor unit
assembly language
