Level 1 cache is cache built into the microprocessor and contains a subset of the contents of the L2 cache.
in systems with two separate sets of cache memory between the CPU and standard memory, the set nearest the CPU. L1 cache is often provided within the same integrated circuit that contains the CPU. In operation, the CPU accesses L1 cache memory; if L1 cache memory does not contain the required reference, it accesses L2 cache memory, which in turn accesses standard memory, if necessary. [SILC99
Level 1 cache is a small piece of very fast memory that's on the CPU chip itself, usually meant for holding instructions as they get executed. It sits between the CPU registers and the L2 cache.
A memory cache built into i486 and higher-level processors. The L1 cache, typically containing 8 KB, can be read in a single clock cycle, so it is tried first. The i486 contains one L1 cache; the Pentium contains two, one for code and one for data. Also called level 1 cache, on-chip cache. See also cache, i486DX, Pentium.

A small amount of high-speed memory located on the CPU. Frequently accessed data is kept in the L1 cache so it won't have to be fetched from the main memory, which takes longer. The size and speed of the L1 cache in a computer can have a significant impact on performance.
A small amount of SRAM memory used as a cache that is integrated or packaged within the same module as the processor. It is clocked at the same speed of the processor. L1 cache is used to temporarily store instructions and data, making sure the processor has a steady supply of data to process while the memory catches up delivering new data.
Level 1 cache. A small cache integrated in a processor that provides quick access to the most recently used data.
The first cache accessed when a storage reference occurs.
