A Simple FASTBUS Slave Interface Using PALs

In any bus system, it is desirable to implement the basic bus protocol with a standard interface. The paper describes such an interface which has been developed for FASTBUS Slave modules. The interface supports all FASTBUS Address and Data Cycles. Major parts of the interface have been implemented in programmable array logic (PALs*) which reduces the space occupied by the interface to less than 10% of the board area.
