This paper describes Fido, a predictive cache [Palmer 19901 that prefetches by employing an associative memory to recognize access patterns within a context over time. Repeated training adapts the associative memory contents to data and access pattern changes, allowing on-line access predictions for prefetching. We discuss two salient elements of Fido MLP, a replacement policy for managing prefetched objects, and Estimating Prophet, the component that recognizes patterns and predicts access.
