Abstract
This paper presents an implementation independent approach to cache memories with states of blocks and kinds of blocks.An implementation independent description of states of blocks in a tightly coupled multi-processor system with private caches is presented, which distinguishes between (abstract) states of blocks and (implementation oriented) tags. Two approaches to cache consistency protocols are described using abstract states: the
ownership
approach and the
responsibleness
approach.Blocks are looked at as constituents of logical entities such as segments. Different kinds of blocks are distinguished based on different kinds of segments. Whenever caches are able to distinguish between different kinds of blocks, then cache schemes, block sizes, and other implementation related aspects may be chosen independently, facilitating a separation of concerns.
