The dynamic interplay between processor speed and memory access times has rendered cache performance a critical determinant of computing efficiency. As modern systems increasingly rely on hierarchical ...

Editor’s Note: Demand for increasing functionality and performance in systems designs continues to drive the need for more memory even as hardware engineers balance the dynamics of system capability, ...

The gap between the performance of processors, broadly defined, and the performance of DRAM main memory, also broadly defined, has been an issue for at least three decades when the gap really started ...

The memory hierarchy (including caches and main memory) can consume as much as 50% of an embedded system power. This power is very application dependent, and tuning caches for a given application is a ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

This section describes three topics discussed in other chapters that are fundamental to memory hierarchies. Protection and Instruction Set Architecture Protection is a joint effort of architecture and ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

System-on-chip (SoC) architects have a new memory technology, last level cache (LLC), to help overcome the design obstacles of bandwidth, latency and power consumption in megachips for advanced driver ...

MIT researchers developed Attention Matching, a KV cache compaction technique that compresses LLM memory by 50x in seconds — ...

AMD's 7800X3D and 7950X3D CPUs reign supreme in the gaming realm, not solely due to their core count or clock speeds, but primarily owing to their abundant cache. CPU cache refers to a small yet ...
