On the Energy-Efficiency of Byte-Addressable Non-Volatile Memory
Non-volatile memory (NVM) technology holds promise to replace SRAM and DRAM at various levels of the memory hierarchy. The interest in NVM is motivated by the difficulty faced in scaling DRAM beyond 22 nm and, long-term, lower cost per bit. While offering higher density and negligible static power (leakage and refresh), NVM suffers increased latency and energy per memory access. This paper dev…

On-Demand Dynamic Branch Prediction
In out-of-order (OoO) processors, speculative execution with high branch prediction accuracy is employed to achieve good single thread performance. In these processors the branch prediction unit tables (BPU) are accessed in parallel with the instruction cache before it is known whether a fetch group contains branch instructions. For integer applications, we find 85 percent of BPU lookups are d…

Persistent Transactional Memory
This paper proposes persistent transactional memory (PTM), a new design that adds durability to transactional memory (TM) by incorporating with the emerging non-volatile memory (NVM). PTM dynamically tracks transactional updates to cache lines to ensure the ACI (atomicity, consistency and isolation) properties during cache flushes and leverages an undo log in NVM to ensure PTM can always consis…

Peripheral Memory: A Technique for Fighting Memory Bandwidth Bottleneck
Memory bottleneck has always been a major cause for limiting the performance of computer systems. While in the past latency was the major concern, today, lack of bandwidth becomes a limiting factor as well, as a result of exploiting more parallelism with the growing number of cores per die, which intensifies the pressure on the memory bus. In such an environment, any additional traffic to memor…

On Optimal Kernel Size for Integrated CPU-GPUs – A Case Study
Integrated CPU-GPU architectures with a fully addressable shared memory completely eliminate any CPU-GPU data transfer overhead. Since such architectures are relatively new, it is unclear what level of interaction between the CPU and GPU attains the best energy efficiency. Too coarse grained or larger kernels with fairly low CPU - GPU interaction could cause poor utilization of the shared resou…

CIDR: A Cache Inspired Area-Efficient DRAM Resilience Architecture against Pe…
Faulty cells have become major problems in cost-sensitive main-memory DRAM devices. Conventional solutions to reduce device failure rates due to cells with permanent faults, such as populating spare rows and relying on errorcorrecting codes, have had limited success due to high area overheads. In this paper, we propose CIDR, a novel cache-inspired DRAM resilience architecture, which substantia…

Coding Last Level STT-RAM Cache For High Endurance And Low Power
STT-RAM technology has recently emerged as one of the most promising memory technologies. However, its major problems, limited write endurance and high write energy, are still preventing it from being used as a drop-in replacement of SRAM cache. In this paper, we propose a novel coding scheme for STT-RAM last level cache based on the concept of value locality. We reduce switching probability in…

Diversity: A Design Goal for Heterogeneous Processors
A growing number of processors have CPU cores that implement the same instruction set architecture (ISA) using different microarchitectures. The underlying motivation for single-ISA heterogeneity is that a diverse set of cores can enable runtime flexibility. Modern processors are subject to strict power budgets, and heterogeneity provides the runtime scheduler with more latitude to decide the l…

DRACO: A Deduplicating FTL for Tangible Extra Capacity
The rapid random access of SSDs enables efficient searching of redundant data and their deduplication. However, the space earned from deduplication cannot be used as permanent storage because it must be reclaimed when deduplication is cancelled as a result of an update to the deduplicated data. To overcome this limitation, we propose a novel FTL scheme that enables the gained capacity to be us…

DRAMA: An Architecture for Accelerated Processing Near Memory
Improving energy efficiency is crucial for both mobile and high-performance computing systems while a large fraction of total energy is consumed to transfer data between storage and processing units. Thus, reducing data transfers across the memory hierarchy of a processor (i.e., off-chip memory, on-chip caches, and register file) can greatly improve the energy efficiency. To this end, we propos…

DRAMSim2: A Cycle Accurate Memory System Simulator
In this paper we present DRAMSim2, a cycle accurate memory system simulator. The goal of DRAMSim2 is to be an accurate and publicly available DDR2/3 memory system model which can be used in both full system and trace-based simulations. We describe the process of validating DRAMSim2 timing against manufacturer Verilog models in an effort to prove the accuracy of simulation results. We outline t…

Dynamic Resource Sharing for High-Performance 3-D Networks-on-Chip
3D logic-on-logic technology is a promising approach for extending the validity of Moore’s law when technology scaling stops. 3D technology can also lead to a paradigm shift in on-chip communication design by providing orders of magnitude higher bandwidth and lower latency for inter-layer communication. To turn the 3D technology bandwidth and latency benefits into network latency reductions …
