Micro BTB: A High Performance and Storage Efficient Last-Level Branch Target Buffer for Servers

Vishal Gupta

High-performance branch target buffers (BTBs) and the L1I cache are key to high-performance front-end. Modern branch predictors are highly accurate, but with an increase in code footprint in modern-day server workloads, BTB and L1I misses are still frequen ...

Unified prefetching into instruction cache and branch target buffer

Babak Falsafi, Boris Robert Grot, Ilknur Cansu Kaynak

A system and method of coupling a Branch Target Buffer (BTB) content of a BTB with an instruction cache content of an instruction cache. The method includes: tagging a plurality of target buffer entries that belong to branches within a same instruction blo ...

Shared Frontend for Manycore Server Processors

Ilknur Cansu Kaynak

Instruction-supplymechanisms, namely the branch predictors and instruction prefetchers, exploit recurring control flow in an application to predict the applicationâ s future control flow and provide the core with a useful instruction stream to execute in ...

Confluence: unified instruction supply for scale-out servers

Babak Falsafi, Boris Robert Grot, Ilknur Cansu Kaynak

Multi-megabyte instruction working sets of server workloads defy the capacities of latency-critical instruction-supply components of a core; the instruction cache (L1-I) and the branch target buffer (BTB). Recent work has proposed dedicated prefetching tec ...

GPU Acceleration for Simulating Massively Parallel Many-Core Platforms

David Atienza Alonso, Luca Benini, Martino Ruggiero, Shivani Raghav

Emerging massively parallel architectures such as a general-purpose processor plus many-core programmable accelerators are creating an increasing demand for novel methods to perform their architectural simulation. Most state-of-the-art simulation technolog ...

Temporal instruction fetch streaming

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

L1 instruction-cache misses pose a critical performance bottleneck in commercial server workloads. Cache access latency constraints preclude L1 instruction caches large enough to capture the application, library, and OS instruction working sets of these wo ...

Last-touch correlated data streaming

Babak Falsafi, Michael Ferdman

Recent research advocates address-correlating predictors to identify cache block addresses for prefetch. Unfortunately, address-correlating predictors require correlation data storage proportional in size to a program's active memory footprint. As a result ...
