Next-Generation Championship in Branch Prediction (CBP-NG), hosted by Ampere Computing.
In conjunction with ISCA 2026
Raleigh, NC, USA
Building on the strong history of previous branch prediction
championships, CBP-NG adds a new twist: it is the first to directly
consider the energy consumed and latency required to compute predictions
in addition to (of course!) accuracy. Participants are invited to
submit predictors (code and papers) with their best energy-efficient,
high-performance branch prediction algorithm. Predictors will be
implemented in a new framework measuring energy, prediction latency, and
accuracy on hard-to-predict workloads including newly-released traces
from Ampere Computing.
Submissions will be selected based on how well the predictor
maximizes the championship score (defined under the Scoring section at https://cbp-ng.bpchamp.com/rules)
across the set of judging traces. The practicality of the design and
quality of the paper and submitted code will also be considered. Novelty
which improves important metrics is highly encouraged. Top submissions
will be invited to present their designs as an ISCA 2026 workshop on
June 28th, 2026 in Raleigh, NC.
Additional information on CBP-NG and how to participate may be found on our website: https://cbp-ng.bpchamp.com/. We look forward to seeing you there!
