传统的缓存对软件是透明的，但无法直接利用摩尔定律结束和通用处理器速度的速度，对专业化的重视和兴趣越来越大。内存（CLAM），可以增加软件和硬件之间的接口，并让编译器控制缓存管理启用。超出传统内存系统设计的优化。从多个台式套件进行测试。
Traditional caching is transparent to software but cannot utilize program information directly. With Moore’s Law ending and general-purpose processor speed plateauing, there is increasing importance and interest in specialization including the interaction between the software and the cache. This paper presents Compiler Lease of cAche Memory (CLAM) which augments the interface between software and hardware and lets a compiler control cache management. The new software control enables optimization beyond what is possible in traditional memory system designs. CLAM has been implemented on a CycloneV-GT FPGA card with a RISC-V processor and the new hardware cache, and the evaluation has shown performance improvements over existing techniques in all of the 7 programs tested from the Polybench suite.
