MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The fastest portion of the CPU cache is the register file, which contains multiple registers. Registers are small storage locations used by the CPU to store instructions and data. The next fastest form of cache memory is Level 1 cache, located on the CPU itself.

Detailed explanation-2: -The CPU cache stands at the top of this hierarchy, being the fastest. It is also the closest to where the central processing occurs, being a part of the CPU itself. According to Tech Target, “Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request."

Detailed explanation-3: -Level 1 (L1) is the fastest type of cache memory since it is smallest in size and closest to the processor. Level 2 (L2) has a higher capacity but a slower speed and is situated on the processor chip. Level 3 (L3) cache memory has the largest capacity and is situated on the computer that uses the L2 cache.

Detailed explanation-4: -Cache is the temporary memory officially termed “CPU cache memory.” This chip-based feature of your computer lets you access some information more quickly than if you access it from your computer’s main hard drive.

Detailed explanation-5: -Fastest memory is cache memory. Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster. More items
