TRACKING WITH CLOSEUPS: IBM Patent Application for “Telum” Mainframe CPU Cache

The unusual “cache virtual memory” architecture of the next generation “Telum” processors for IBM's Z-Series mainframes was discussed here on 2021-09-03. IBM have filed a U.S. patent application, US 2021/0026783 A1 [PDF], on 2021-01-28 which describes the “black magic” behind how it maintains consistency and low latency with multiple levels of processors sharing cache and “borrowing” storage from one another.
