Multibank cache with dynamic cache virtualization

A cache controller, comprising:

• a processor interface to communicatively couple to one or more computing cores;
• a cache interface comprising n discrete cache buses of width b to communicatively couple to a cache having n cache banks of the same level;
• and
• cache access circuitry to:
• receive a cache access request to read from or write to the cache an object having a size s, wherein s>b;
• divide the object into k chunks, the chunks having a size b;
• and
• perform a cache access operation in one or more transactions, wherein the transactions comprise reading chunks of the object from or writing chunks of the object to a plurality of cache banks in parallel.

A method of controlling a cache, comprising:

• communicatively coupling to one or more computing cores;
• communicatively coupling a cache interface comprising n discrete cache buses of width b to a cache having n cache banks of the same level;
• and
• receiving a cache request to fetch or store an object having a size s, wherein s>b;
• dividing the object into k chunks of size b or smaller;
• and
• fetching or storing the object comprising one or more iterations of transferring n parallel chunks of the object via the n cache buses.
