MSIO Infrared Controller Logic 5-6 Super I/O Controller Serial UARTs Two 16550A-compatible UARTS are provided in the MSIO. They can be mapped to any of the standard legacy I/O addresses and interrupts. UART-A is dedicated to the RS-232 transceiver and serial connector on the back of the unit. UART-B interfaces internally to an IrDA-compliant infrared encode/decoder and an IrDA module for serial infrared communications. Information on configuration of the UARTs can be found in the MSIO documentation. Shared Flash ROM Interface The MSIO provides a means for the system processor to access the 8051 ROM, so that a single Flash ROM device, shown in Figure 5-7, can be used to store system BIOS as well as 8051 code. To prevent simultaneous access by both processors, the 8051 enters the idle mode and stops its internal clock when the reset-out line (SYS_RESET#_3) is deasserted by the 8051 to PXII4M. The system CPU then has control of the ROM interface and "boots" from the ROM. After executing some very basic test routines, the BIOS code copies itself into system DRAM, begins to execute from DRAM, then starts the 8051 clock again. The system does not need to access the ROM again until it loses power to the DRAM. Host CPU ROM nCS ISA Bus AD[7:0] ALE FDC37N97X LATCH FLASH 512 x 8 ADDR[17:8] nKBWR nKBRD nCE Figure 5-7. The support functions ensure efficient transfer of audio data streams to and from system memory buffers, providing a system solution with maximum performance and minimal host CPU loading. The architecture enables implementation of communications over the Internet from multiple sources.

ESS Maestro 2E Block Diagram used in the Armada E500 and Armada V300 Computers The M2E has a variety of audio interfaces. The secondary AC'97 CODEC interface is used to handle the Docking station CODEC interface. The M2E, which operates at 3. 3 volts, has several special features for notebook operation, including compliance with the Advanced Power Management (APM) 1. 2, Advanced Configuration and Power Interface (ACPI) 1. 0, and PCI Power Management Interface (PPMI) 1. 0. The M2E has multiple power-saving modes (D0, D1, D2, and D3) for power-efficiency when the audio system is both active and idle. Its high-quality docking solution supports an AC link-based digital docking solution with its secondary 20-bit AC link. This helps achieve the lowest power consumption in D3 hot mode. 6-2 Audio Subsystem The device supports full DOS game compatibility for both PC motherboard and add-in card solutions through three hardware implementations: PC/PCI, Distributed DMA (DDMA), and Transparent DMA (TDMA). While PC/ PCI and DDMA are industry-standard protocols for legacy support, ESS's TDMA technology implements DOS game compatibility over the standard PCI 2. 1 bus.

Besides the low power CMOS technology used to process the M2E, various features are designed into the device to provide benefits from popular power-saving techniques. These features and techniques are discussed in this section. CLKRUN Protocol The PCI CLKRUN feature is one of the primary methods of power management on the PCI bus interface of the M2E for the notebook computer. Audio Subsystem 6-3 PCI Power Management Interface (PPMI) The PCI Power Management Interface (PPMI) specification establishes the infrastructure required to let the operating system control the power of PCI functions. [. . . ] Once the CPU has generated a Quick Start special cycle and moved the Quick Start state, stopping the CPU clock input causes the CPU to enter the Deep Sleep state. To return to Full-On, the CPU clock must be restarted and remain stable for 1 millisecond. From there, the return to full on is completed by de-asserting the STPCLK# signal. Deep Sleep state is used only during Standby because of the 1 millisecond latency. Processor Thermal Management The processor temperature is monitored by the CPUTEMP signal. [. . . ]
