What three major components does the Northbridge interface with?
RAM, GPU, and CPU
100
What kinds of data do CPUs process?
Floating Point and Integer instructions (Bonus: SIMD)
100
What is the purpose of L2 cache?
To overcome the limitations of L1 cache. L1 cache is limited in how large it can be. L2 cache can be much larger than L1 cache. It also can be used to interface between multiple CPU cores.
200
What is the function of a CPU?
It is the main computational unit of a computer. It is responsible for the processing of data
200
How many levels of cache are there?
There are three different levels of cache.
200
What is the purpose of L3 cache?
Like L2 cache, it is to overcome the inherent limitations of L2 cache; its size. L3 cache can be larger than L2 cache. It also has the ability to interface between multiple cores. L3 cache can also interface between a CPU and a GPU.
300
How does the CPU interact with the rest of the system?
Via the Chipset. The CPU is interfaced by the Northbridge.
300
What is the purpose of L1 cache?
It holds both CPU instructions, and also fulfills the need to hold data within a core.
300
What is L4 cache?
It is a hybrid Cache that fulfills the role of fast access RAM for GPUs, while at the same time, it fills the general purpose of Cache RAM at the same time.
400
What does the Northbridge and Southbridge makeup?
The chipset
400
What is Cache RAM?
It is a memory internal to the CPU. Although there is RAM to act as a conduit between the CPU and the HDD, even RAM isn’t fast enough to keep up with the HDD. Cache RAM is needed to overcome this. It also serves the purpose so that the CPU can hold data. (Bonus: L1 instruction cache holds instructions for the CPU)
500
What is RAM? What is its function?
RAM is Random Access Memory. It acts as a conduit between the processor and the HDD, since the CPU is running exponentially faster than the HDD.
500
What are the different types of L1 cache?
instruction cache and data cache
