....ability to be easily integrated across a wide variety of buses. Unfortunately, standardizing on one or two on chip buses does not appear to be possible, because of the diversity of constraints present in embedded systems, as recognized for example by the Virtual Socket Interface Alliance (VSIA) [4]. Thus, to achieve such ease of integration, many have proposed designing cores with their interface behavior kept separate from their internal behavior [4] 5] 6] This is especially true for peripheral cores, for which portability is a key issue.

Such separation isolates any bus specific changes to a small region of the core, which we will call an interface module (IM) However, such modularity often comes with a performance penalty. For example, ....

....has led to the marketability of Intellectual Property (IP) cores, available in various forms ranging from soft cores to hard cores (e.g. 4] The ability to easily integrate a core into a system can increase a core s usefulness. Early efforts by the Virtual Socket Interface Alliance (VSIA) [12] focused on defining a standard on chip bus, but this was soon viewed to be infeasible. Instead, they are now defining a standard that prescribes creating cores with internal behavior separated from the bus interface logic through a bus wrapper. Other researchers have also proposed such separation ....
