OVP Peripheral Model: ArmLcdPL110



Model Specific Information

This page provides introductory usage information for an Imperas OVP peripheral behavioral model. The page is split into sections providing specific information for this peripheral, including any ports for connecting into a platform, registers, other component parts, and configuration options and general information for peripheral modeling with Imperas OVP.

Description

ARM PL110 LCD Controller

Limitations

The VGA display refresh is not optimised resulting in the VGA peripheral causing a limit on the maximum performance of a platform it contains to be around 300 MIPS (actual dependent upon refresh rate of LCD).

The LCD peripheral utilises memory watchpoints to optimise display refresh. This requires the use of ICM memory for the frame buffers, which currently may stop its use in SystemC TLM2 platforms.

Interrupts are not supported
