Jacob, BruceBhattacharyya, Shuvra S.This paper demonstrates the intractability of achieving statically predictable performance behavior with traditional cache organizations (i.e., the real-time cache problem) and describes a non-traditional organization—combined hardware and software techniques—that can solve the real-time cache problem. We show that the task of placing code and data in the memory system so as to eliminate conflicts in traditional direct-mapped and set-associative caches is NP-complete. We discuss alternatives in both software and hardware that can address the problem: using address translation with software support can eliminate non-predicted conflict misses, and explicit management of the cache contents can eliminate non-predicted capacity misses. We present a theoretical analysis of the performance benefits of managing the cache contents to extend the effective size of the cache.en-USreal-time cachesmemory systems for real-time systemsstatic & dynamic cache managementTechnical Report
