Architecture

The architecture of the 17-inch MacBook Pro is based on the Intel Core Duo microprocessor and two custom ICs, the North Bridge memory controller and the South Bridge I/O controller, connected to each other by a Direct Media Interface (DMI) bus. The North Bridge IC provides the bridging functionality among the processor, the memory system, the DMI, and the 16-lane PCI Express bus to the graphics controller. The South Bridge IC supports these components:

• Ultra ATA/100 bus for the optical drive (running at UATA/66)

• A 1.5 Gbps Serial ATA (SATA) bus for the disk drive

• 1-lane PCI Express link for the AirPort Extreme module

• SPI bus, direct memory access bus to the boot ROM

• USB 2.0 controller, which in turn supports the Bluetooth module, IR receiver, built-in iSight camera, built-in trackpad and keyboard, ExpressCard/34 slot, and 3 external USB 2.0 ports

• Channel to the audio subsystem

• 1-lane PCI Express link for the Ethernet PHY

• 33 MHz, 32-bit internal PCI bus to the FireWire 400 (1394a) and FireWire 800 (1394b) OHCI and PHY

• 1-lane PCI Express link and one USB 2.0 interface for the ExpressCard 34 mm slot

A DMA controller internal to the South Bridge supports LPC DMA (low pin count direct memory access). The DMA controller has registers that are fixed in the lower 64 KB of I/O space. The DMA controller is configured using registers in the PCI configuration space.

Figure 1 provides a simplified block diagram of the North Bridge and South Bridge ICs and the buses that connect them together.

Features

The 17-inch MacBook Pro computer includes a built-in iSight video camera, an integrated IR receiver, and the Apple Remote. For a complete list of user-visible features, see the 17-inch MacBook Pro specification sheet at Apple's Specifications site. Other features are described in this section.

Intel Core Duo Microprocessor

The microprocessor in the 17-inch MacBook Pro is an Intel Core Duo with a clock speed of 2.16 GHz. It has the following features:

• 2.16 GHz dual core processors

• 2 MB shared L2 cache

• Digital Media Boost

• Connection to the North Bridge IC over a 667 MHz frontside bus

See the Intel Core Duo Processors support site for detailed microprocessor documentation.

Digital Media Boost

Intel Digital Media Boost accelerates data manipulation by applying a single instruction to multiple data at the same time, known as SIMD processing. SIMD technology accelerates vector math operations and floating-point calculations. Digital Media Boost supports Intel Streaming SIMD Extensions (SSE) versions 1, 2, and 3.

For information on Digital Media Boost, refer to the following websites.

http://www.intel.com/products/processor/coreduo/digitalmediaboost.htm

Processor Bus

The processor bus is an up-to-667 MHz bus connecting the processor to the North Bridge IC. The data bus is 64-bit wide. The processor has 32-bit addressing.

The point-to-point architecture provides each subsystem with dedicated bandwidth to main memory. The North Bridge IC implements an independent processor interface. The input clock to the processor PLL is 166 MHz.

Memory

The computer provides two RAM slots that accommodate 200-pin DDR2 SDRAM SO-DIMMs up to 1.25” in height. The SO-DIMMs must be DDR2 PC2-5300-compliant and must be unbuffered, unregistered, 8-byte, nonparity, and non-ECC. For additional information, refer to RAM Expansion Developer Note.

Direct Media Interface Bus

The North Bridge and South Bridge ICs are connected by a Direct Media Interface (DMI) bus, a high-speed, bidirectional, point-to-point link supporting a clock rate of 1 GB per second in each direction

Extensible Firmware Interface (EFI) Boot ROM

The Extensible Firmware Interface (EFI) Boot ROM consists of 2 MB of on-board flash EEPROM. It includes the hardware-specific code and tables needed to start up the computer, load an operating system, and provide common hardware access services.The EFI Boot ROM connects to the South Bridge via Serial Peripheral Interface (SPI) bus.

Graphics/Video Subsystem

The graphics subsystem includes an ATI Mobility Radeon X1600 IC, with 256 MB GDDR3 SDRAM, connected to the North Bridge IC by a x16 link (16 lane), dual simplex, 2.5 GHz PCI Express bus. The 17-inch MacBook Pro has a dual-link DVI connector for an external video monitor and supports video mirroring mode and extended desktop display mode. For more information on the graphics subsystem and display capabilities, refer to Video Developer Note.

For more information on PCI Express, refer to PCI Developer Note.

Serial ATA Drive Interface

The 17-inch MacBook Pro comes with a 120 GB 5400 rpm (optionally, a 100 GB 7200 rpm) Serial ATA (SATA) Gen-I (1.5 Gbps) disk drive. The SATA disk drives operate through an AHCI 1.1 controller that supports advanced SATA-II features such as Native Command Queuing (NCQ) and PHY power management.

For more information on SATA, see the Serial ATA International Organization (SATA-IO) website.

For information on the AHCI controller, see http://www.intel.com/technology/serialata/ahci.htm.

Ultra ATA Interface

In the 17-inch MacBook Pro computer, the South Bridge controller provides an Ultra ATA/100 interface (running at UATA/66) to the slot-loading, SuperDrive. The drive can read and write DVD media and CD media, as shown in Table 1.

The SuperDrive is configured as device 0 (master) and complies with the ATA/ATAPI-5 industry standard. For information on parallel ATA interfaces, see the International Committee on Information Technology Standards (INCITS) Technical Committee T13 AT Attachment website.

FireWire Controller

The computer has one IEEE-1394a FireWire 400 port, which supports transfer rates of 100, 200, and 400 Mbps and one IEEE-1394b FireWire 800 port, which supports 800 Mbps transfer rates in addition to 1394a transfer rates. For more information, see FireWire Developer Note.

Ethernet Controller

The computer has a built in Ethernet port for a 10BASE-T/UTP, 100BASE-TX and 1000BASE-T Gigabit operation. For more information, see Ethernet Developer Note.

USB 2.0 Controller

The South Bridge IC includes an integrated USB 2.0 controller supporting the Bluetooth module, IR receiver, built-in iSight camera, built-in trackpad and keyboard, Express Card/34 slot, and 3 external USB 2.0 ports. The USB ports comply with the Universal Serial Bus Specification 2.0. For more information, see Universal Serial Bus Developer Note.

AirPort Extreme and Bluetooth 2.0 + EDR Module

The 17-inch MacBook Pro computer has an internal AirPort Extreme module, connected to a dedicated 1-lane PCI Express link, and a Bluetooth 2.0 + EDR (enhanced data rate) module, connected to the USB 2.0 controller. AirPort Extreme and Bluetooth have independent built-in antennas. AirPort Extreme has two antennas built into the display clutch barrel. Bluetooth has a single antenna along the left edge of the body, to the left of the palm rest. For more information, see AirPort Developer Note and Bluetooth Developer Note.

Audio System

The computer has a built-in microphone, a combination analog audio line-in and S/PDIF digital optical audio line-in jack, and a combined analog output and S/PDIF digital optical audio line-out jack. For more information, see Audio Developer Note.

System Management Controller

The MacBook Pro uses an advanced system management controller (SMC) to manage thermal and power conditions, while keeping the acoustic noise to a minimum. The SMC is fully independent of the operating system.
