CHAPTER 2 Architecture Main ICs and Buses The architecture of the PowerBook G4 17-inch computer is designed around the PowerPC G4 microprocessor and Intrepid IC that contains the memory controller and I/O device controller. The PowerPC G4 microprocessor is connected to the Intrepid IC by a MaxBus bus. The bus clock speed is 167 MHz. Other buses that connect with the Intrepid IC are summarized in Table 2-1 (page 19), which is in the section “Intrepid Controller and Buses” (page 19). The Intrepid
