Awards, Honors, and Impact

2012 Computer Architecture Letters paper selected to be presented in the Best of CAL Ses-

sion at HPCA 2012.

2011 Neural branch predictors inspired by Jimenez's research are documented to be imple-'

mented in current microprocessors including the AMD Fusion C-series and E-series

APUs and the Oracle SPARC T4. Quotes from industry literature:

One particularly interesting feature is the Neural Net Logic Branch Pre-

dictor, which is designed to improve the ability of Series C and Series E

APUs to deliver performance for today's workloads. from APU 101: All

about AMD Fusion Accelerated Processing Units, emphasis added

The SPARC T4 processor incorporates new features such as Out-Of-Order

(OOO) execution of instructions,branch prediction using a simple neural

net algorithm, cryptographic processing integrated directly within the in-

struction pipeline with user-level access, and longer pipelines that enablea

higher clock rate. from Overview and Frequently Asked Questions Oracle

SPARC T4-4, emphasis added

The SPARC T4 has Perceptron branch prediction (neural net / AI -vs-

heuristic) from Oracle PartnerNetwork Day Satellite Event Italia, 31
