Embedded Systems Dilemma of Chip Memory Diversity by Scratchpad Memory for Cache On-chip Memory

-The aim of this paper is the problem of chip memory selection for computationally intensive applications by proposing scratch pad memory as an alternative to cache. Area and energy for different scratch pad and cache size are computed using CACTI tools w hile performance was evaluated using the trace resu lts. In this paper, an algorithm integrated into a compiler is presented which analyses the application and se lect program and data parts which are placed into the sc ratchpad. Comparisons against a cache solution show remarkable advantages between 12% and 43% in energy consumption for designs of the same memory size. Key Words-Scratchpad Memory, Cache Memory, CACTI, C ompiler, Memory.
