초록
Disclosed are a cache with a scratch pad memory (SPM) structure and a processor including the same. The cache with a scratch pad memory structure includes: a block memory configured to include at least one block area in which instruction codes read from an external memory are stored; a tag memory configured to store an external memory address corresponding to indexes of the instruction codes stored in the block memory; and a tag controller configured to process a request from a fetch unit for the instruction codes, wherein a part of the block areas is set as a SPM area according to cache setting input from a cache setting unit. According to the present invention, it is possible to reduce the time to read instruction codes from the external memory and realize power saving by operating the cache as the scratch pad memory.
