L1datavälimuisti, often referred to as L1 data cache, is a small, extremely fast memory located on the CPU chip itself. It serves as the first level of cache that the processor accesses for data. Its primary purpose is to reduce the average time required to access data from main memory, which is significantly slower. The L1 data cache is typically divided into two parts: one for instructions and one for data, though the term L1 datavälimuisti specifically refers to the data portion.
This cache stores frequently used data, allowing the CPU to retrieve it almost instantaneously without needing
