Wishbone (computer bus)

The Wishbone Bus is an open source hardware computer bus intended to let the parts of an integrated circuit communicate with each other. The aim is to allow the connection of differing cores to each other inside of a chip. The Wishbone Bus is used by many designs in the OpenCores project.

Wishbone topologies
Wishbone adapts well to common topologies such as point-to-point, many-to-many (i.e. the classic bus system), hierarchical, or even switched fabrics such as crossbar switches. In the more exotic topologies, Wishbone requires a bus controller or arbiter, but devices still maintain the same interface. Shared bus Data flow Crossbar switch ==Comparisons==
