Abstract Wavefront alignment, an irregular workload, spans CPUs, GPUs, FPGAs, ASICs and processing-in-memory, each benchmarked in isolation. We re-measure every implementation we could run under one gap-affine objective, on four CPU and four GPU configurations, across synthetic and real data, indexed by alignment score.

Abstract Deepfake detectors achieve strong benchmark performance but remain difficult to interpret and can degrade under unseen manipulation methods, compression and acquisition conditions. We present PRISM (Physics-Reality Integrated Signal Multistream) a video-level framework based on 50 explicit handcrafted forensic descriptors capturing sensor-residual, physiological, geometric, motion, texture, illumination and compression evidence.
