Cache Memory and Multicore Processors"
From the e-Activity, determine the type of cache memory (i.e., Level 1, Level 2,
or another type) that resides on a computer that you own or on a computer that
you would consider purchasing.
CPU #1 – My Computer
Total L2 Cache 2MB -
It works together with the L1 and L2 cache to improve computer
performance by preventing bottlenecks due to the fetch and execute cycle taking too long. The
L3 cache feeds
to the L2 cache, which then forwards information to the L1 cache.
Typically, its memory performance is slower compared to L2 cache, but is still faster than the
main memory (RAM).
Total L1 Cache 38KB -
Both of these depend on the CPU. There are CPUs which have no cache
at all, there are CPUs which have the L1 cache on die and the L2 cache on a separate die on the
same chip or even on a separate chip, or there are CPUs which have both L1 and L2 cache on the
same die as the CPU core.
Because L2 Cache works with L1 and L2 Improving computer performance allowing for easier
traffic flow , and because L3 feeds information to the L2 cache providing for better computer
performance I’m sticking with what I have.
It was also cost affect also.
Examine the primary manner in which the type of cache memory that you have
identified interfaces with the CPU and memory on your computer. Determine
which type of cache memory is the most efficient and provide one (1) example
that depicts the manner in which the use of one (1) type of cache memory makes
your computer processing more efficient than another.
L1 and L2 cuts access latencies and reduces the chance of cache contention — meaning two
different cores won’t overwrite vital data that the other put in a location in favor of their own
workload. The common L3 cache is slower but much larger, which means it can store data for all
the cores at once. Sophisticated algorithms are used to ensure that Core 0 tends to store
information closest to itself, while Core 7 across the die also puts necessary data closer to itself.
