Abstract
A generic interface controller for a processor to peripheral device interface. This circuit eliminates marginal timing between a processor and a plurality of different peripheral devices while providing read and write operations within a minimum amount of cycle time. The processor interface controller generates read, write and acknowledge signals. This controller is particularly useful for ASIC applications where some of the peripheral devices such as memory, may be co-located on the ASIC circuit while other peripheral devices may be remotely located from the application Specific Integrated Circuit (ASIC) circuit.
