The Best designed computer system Architecture

CPUComputer Architecture  has a great effect on security and performance. The key components of good Computer Architecture and performance are as follows:

• Central Processing Unit (CPU) – gets instructions from memory and executes them.  Some high end CPU’s are:

  1. AMD Ryzen Threadripper 2950X @  3.5 GHz 16 core $654
  2. Intel Core i9-9900X @ 3.50GHz  3.5 GHz  10 cores (2 logical cores per physical) $899
  3. Intel Core i7-9800X @ 3.80GHz 8 cores (2 logical cores per physical) $899

• Registers – points to memory locations that contain next set of instructions to execute.

• Arithmetic logic unit (A.L.U) does the actual execution of instructions.

• Control unit manages and synchronizes system while application code and Operating System instructions are executed.

• General Register – hold variables and temporary results.

• Program status word holds conditional bit, should CPU be working in user mode (problem state) or privileged mode (kernel / supervisor mode).

• To access data, CPU sends fetch request on address bus.

Random Access Memory – temporary storage facility where data & program instructions can be temporarily held and altered. Volatile means that loss of power results in  loss of data.

Hardware segmentation – memory is separated physically instead of just logically. This help protect higher level process’s memory space.

Cache memory- high speed writing and reading activities.

Motherboards have different types of cache.

• Level 1 – fastest

• Level 2 – 2nd fastest

• Level 3  – 3rd fastest

L1 & L2 is typically built into controllers and processors.

Having a great understand of all the facets that go into computer Architecture allows you to get the best performing system while providing excellent security.
