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.
