1 6 System Software Legacy Document | 2003-03-0 1 | © 2003 Apple Comput er , Inc. All Rights Reserved. CHAPTER 1 Over view of P owerBook G4 1 7-inch.
This chapter describe s the architecture of the P owerBook G4 1 7-inch computer . I t includes information about the major components on the main logic board: the micropr ocessor , the other main ICs, and the buses that connect them to each other and to the I/O interfaces.
Main ICs and Buses The architecture of the P owerBook G 4 1 7-inch computer is designed ar ound the Po werPC G4 microprocessor and Intrepid IC that con tains the memor y controller and I/O device c ontroller . The P owerPC G4 microprocessor is connected to the Intrepid IC b y a MaxBus bus.
Le vel 2 Cache The data storage f or the L2 cache consists of 256 KB of fast static RAM that is built into the micropr ocessor chip along with the cache controller and tag st orage. The built-in L2 cache runs at the same clock speed as the microproce ssor .
Syst em RAM The memory subsystem in the P owerBook G4 1 7-inch computer suppor ts two slots for 3 33 MHz DDR (PC2700) SO-DIMMs (small-outline dual inline memory modules). The data bus to the RAM and DIMM is 64 bits wide, and the memory inter face is synchronized to the MaxBus bus interface at 1 67 MHz.
● support for 6 4 MB of DDR video memor y with 1 28-bit int er face ● 2D and 3D graphics acceleration ● transform accelera tion ● lighting acceleration ● video acceleration ● support for M.
The DB-DMA system pro vides a scatter-gather proc ess based on memor y resident data structure s that describe the data transfers . The DMA engine is enhanced to allow bursting of data file s for improved performance.
The internal modem is a separa te module that contains the data pump IC and the int er face to the telephone line (DAA). F or more information about the modem, see “Internal Modem ” (page 30). Sound Circuitr y The sound circuitry , called Snapper , is connected to the Intrepid IC by a standar d IIS (inter-IC sound) bus.
T wo antennas are built into the c omputer ’ s case. T o improv e reception, a diversity module between the antennas and the card measure s the signal strength from both antennas and selects the stronger signal for AirP or t Extreme. AirP or t Extreme is based on the IEEE draft specification of the 802.
This chapter describes both the built-in I/O de vices and the por ts for connecting external I/O devices. Each of the following sections describes an I/O port or device.
The P owerBook G 4 1 7-inch computer supports all four data transfer types defined in the USB specifica tion. USB devices can pro vide a remote wakeup function for the computer . The USB root hub in the computer is set to support remote wakeup whenever a device is attached to the bus .

This chapter describe s the expansion features of the P owerBook G4 1 7-inch computer ’ s RAM expansion slots and the CardBus slot. RAM Expansion Slots The computer has two RAM expansion slots tha t accommodate standard SO (small outline) DIMMs using DDR SDRAM devices.
Mechanical Design of DDR RAM SO-DIMMs The RAM expansion modules used in the P owerBook G 4 1 7-inch computer are PC2 700 DDR33 3 RAM SO-DIMMs, as defined in the JEDEC specifications. The mechanical characteristics of the RAM expansion SO-DIMM are given in the JEDEC specifica tion for the DDR SO-DIMM.
DDR SDRAM Devices The DDR SDRAM devices used in the RAM expansion modules must be self-r efresh type devices for opera tion from a 2.5 V power supply . The speed of the DDR SDRAM device s must be 1 67 MHz or higher . The devices ar e programmed to operate with a CAS lat enc y of 2.
Note: The P owerBook G4 1 7-inch computer does not use memory interleaving , so installing two SO-DIMMs of the same size does not re sult in any per formance gain.
CardBus Slot The CardBus slot acc epts one T ype I or T ype II card. The slot supports both 1 6-bit PC Cards and 3 2-bit CardBus Cards. T he card can be removed and replac ed while the computer is operating . Note: The CardBus slot does not pro vide 1 2 V power .
