What Is L1 And L2 Cache?
Answer:
1.The Level 1 cache memory is also known also Primary Cache Memory, and is attached with the CPU or Processor and is also it is used for temporary storage of Instructions and background organized in the blocks of 32 bytes. This type of Cache memory is also one of the fastest form of storage Memory used in Computer. Since because it's integrated with chip beside a zero wait-state (delay) interface to the processor's execution unit, where it is restricted in size. And This memory is also implemented using Static RAM (SRAM).
2. Today's most of the PCs are having near Level 2 Cache Memory to extent / bridge the processor / memory performance gap. This memory is also known as lesser Cache Memory and uses the same control logic as Level 1 cache memory do, and is also implemented in SRAM.
Level 2 cache typically comes contained by two sizes, 256KB or 512KB, and can be found, or soldered onto the motherboard. The main Aim of Level 2 Cache Memory is to supply the stored information to the processor without any delay (wait-state). For this purpose, the bus interface of the processor is used for Transfer Protocol call DURST MODE.
Cpu cache or cache memory is used by CPU of a computer to reduce the average time to access memory. The cache is a faster memory which stores the data or copies of the data from the most frequently used principal memory.
L1 cache memory, usually built onto the microprocessor chip itself.
L2 cache memory is on a separate chip, that can be accessed more quickly than the larger or main memory.
