Access to devices can be made software-transparent by including I/O and memory and address mapping logic in Super I/O chip 45 in the PC. When the Super I/O chip traps an I/O or memory access in a preprogrammed range, the Super I/O chip directs data access to the appropriate PCMCIA device plugged into one of the PCMCIA connectors 113, 115, or 117 (if DSP) of the Smart Phone.
