DRAM Aware Last-Level-Cache Policies for Multi-core Systems
x latency DTC in two cycles. In contrast, state-of-the-art DRAM cache always reads the tags from DRAM cache that incurs high tag lookup latencies of up to 41 cycles. In summary, high DRAM cache hit latencies, increased inter-core interference, increased inter-core cache eviction, and the large application footprint of complex applications necessitates efficient policies in order to satisfy the ...
متن کاملLevel-2 Shared Cache versus Level-2 Dedicated Cache for Homogeneous Multicore Embedded Systems
Multicore brings tremendous amount of processing speed. On the contrary, it offers challenges for embedded systems as embedded systems suffer from limited resources. Various cache memory hierarchies are proposed to satisfy the requirements of different systems. Traditionally, level-1 cache memory is dedicated to each core. However, level-2 cache can be shared (like Intel Xenon) or dedicated (li...
متن کاملDRAM-Aware Last-Level Cache Replacement
The cost of last-level cache misses and evictions depend significantly on three major performance-related characteristics of DRAM-based main memory systems: bank-level parallelism, row buffer locality, and write-caused interference. Bank-level parallelism and row buffer locality introduce different latency costs for the processor to service misses: parallel or serial, fast or slow. Write-caused...
متن کاملMapping the Intel Last-Level Cache
Modern Intel processors use an undisclosed hash function to map memory lines into last-level cache slices. In this work we develop a technique for reverse-engineering the hash function. We apply the technique to a 6-core Intel processor and demonstrate that knowledge of this hash function can facilitate cache-based side channel attacks, reducing the amount of work required for profiling the cac...
متن کاملEfficient Cache Locking at Private First-Level Caches and Shared Last-Level Cache for Modern Multicore Systems
Most modern computing systems are having multicore processors with multilevel caches for high performance. Caches increase total power consumption and worsen execution time unpredictability. Studies show that way (or partial) cache locking may improve timing predictability and performance-to-power ratio for both single-core and multicore systems. Even though both private first-level and shared ...
