Emulation Baseboard Model: Platform and Components 7.8 Other Emulation Baseboard components This section briefly describes the purpose of selected additional components included with the Emulation Baseboard platform model. 7.8.1 EBConnector and EBSocket components The EBConnector and EBSocket components are used to forward Interrupts, CLK and PVBus transactions between the EBBaseboard and the Core Tile. As their names indicate, the two components emulate the connections in a Core Tile to the Emulation Baseboard. 7.8.2 EBInterruptForwarder component The EBInterruptForwarder component is an assistant component for EBSocket. EBInterruptForwarder receives all interrupts and is responsible for telling the socket which interrupt happened. 7.8.3 EBRemapper component The EBRemapper component is a control component involved with remapping logic on the Emulation Baseboard. The component receives the remap_clear signal from the SP810_SysCtrl component and boot_switch value from the EB_SysReg component to determine which devices are to be remapped and unremapped. The EB_SysReg component is described elsewhere in this document. See EB_SysRegs component on page 7-13. The SP810_SysCtrl component is described in Chapter 5 Peripheral and Interface Components.

Emulation Baseboard Model: Platform and Components 7.9 Differences between the EB hardware and the system model The following sections describe features of the Emulation Baseboard hardware that are not implemented in the models or have significant differences in implementation: • Features not present in the model • Remapping and DRAM aliasing on page 7-24 • Dynamic memory characteristics on page 7-24 • Status and system control registers on page 7-24 • Generic Interrupt Controller on page 7-24 • GPIO2 on page 7-25 • Timing considerations on page 7-25. 7.9.1 Features not present in the model The following features present on the hardware version of the Emulation Baseboard are not implemented in the system models: • two wire serial bus interface • character LCD interface • smart card interface • PCI controller configuration registers • debug access port • disk on chip • configuration flash • USB • PISMO expansion memory • PCI interface bus windows • UART Modem handshake signals • VGA support. Note For more information on memory-mapped peripherals, see Emulation Baseboard memory map on page 7-3. The following features present on the hardware version of the Emulation Baseboard are only partially implemented in the Real-Time System Models: • Sound • Dynamic memory controller. Partial implementation means that some of the components are present but the functionality has not been fully modeled. If you use these features, they might not work as you expect. Check the model release notes for the latest information. Sound The EB RTSMs implement the PL041 AACI PrimeCell and the audio CODEC as in the EB hardware, but with a limited number of sample rates. Dynamic memory controller The dynamic memory controller, though modeled in the EB RTSMs, does not provide direct memory access to all peripherals. Only the audio and synchronous serial port interface components can be accessed through the DMC. ARM DUI 0423J Copyright © 2008-2011 ARM. All rights reserved. 7-23 ID051811 Non-Confidential
