Peripheral and interface components - about

The Programmer’s View (PV) models behave equivalently to what you would see if you were using hardware. However, they sacrifice accuracy in timing to achieve fast simulation speeds.

You can test software functionality with PV models, but do not rely on the accuracy of cycle counts, low-level component interactions, or other hardware-specific behavior.

The major components are:

  • Bus components, including conversions between AMBA and PV Model components for use with the SystemC export feature of Fast Models.
  • Input/output devices.
  • Memory, including flash.
  • Ethernet controller.
  • Interrupt controllers.
  • Static and dynamic memory controllers.
  • Audio interface.
  • Programmable clock generators.

Some components are software implementations of specific hardware functionality. Components based on PrimeCells are an example. Other components are necessary as part of the modeling environment and do not represent hardware. Examples of the latter category of component are the bus, clock, telnet and visualization components.

Components based on specific hardware functionality are either:

Validated Peripheral Components
Components that are functionally complete, or have clearly specified limitations. These components can be used to create virtual platforms and have been validated.
Example Peripheral Components
Components that have been developed as examples to illustrate ways to model different component types and to enable the creation of specific example virtual platforms. These components can be partially validated.

For information about the hardware, see the technical reference manuals.
