Does PEG support processors that contain internal video controllers?

Yes, we provide screen driver templates that support CPU embedded controllers and those with hardware acceleration capabilities.

Is it easy to port PEG to a new processor?

Yes, because the majority of PEG's library is hardware independent and its hardware interface objects are well defined. The library’s portability has been verified because PEG applications are running on most of the common embedded processors.

Does PEG support any reference platforms?

Yes, PEG supports a variety of popular reference platforms.

For more information see Reference Platforms.

What are the display devices that PEG supports?

For devices that are not on the list, we provide screen driver templates to help you create your own driver. Using a template, your will only need to write three functions; GetVideoAddress(), SetupPalette(), and ConfigureController().

What are the video controllers that PEG supports?

For controllers that are not on the list, we provide screen driver templates to help you create your own driver. The templates support both external and internal (CPU embedded) controllers including those with hardware acceleration capabilities.

What are the input devices that PEG works with?

PEG supports all standard input devices including mouse/joystick, touch screen, keyboard/keypad, and soft keys.

What are the screen drivers included with PEG?

A set of screen driver templates is provided for 1-bpp (monochrome) through 24-bpp (TrueColor RGB) video output and screen resolutions of 1 x 1 to 65535 x 65535 pixels. They are designed to work with any CPU architecture that supports direct, linear access to the video memory buffer.

PEG is fully integrated with RTOS messaging, memory management, and synchronization services. PEG input devices are interrupt driven and use RTOS services to communicate user-input information to the GUI. This yields the lowest possible overhead and the only true real-time multi-tasking GUI environment available.

For more information see RTOS Support.

Does PEG need a file system for normal operation?

No, PEG does not need a file system for normal operation.

What is PEG's level of real-time awareness?

PEG is fully integrated with RTOS messaging, memory management, and synchronization services. PEG input devices are interrupt driven and use RTOS services to communicate user-input information to the GUI. This yields the lowest possible overhead and the only true real-time multi-tasking GUI environment available.

For more information see RTOS Support.

Is it easy to port PEG to an RTOS?

Yes, because PEG makes no assumptions about the software environment. OS-specific dependencies are encapsulated and well documented. Included are examples that you can use to create new interface classes for any environment.

For more information see RTOS Support.

Can PEG run standalone without an RTOS?

Yes, PEG can be run standalone without a multi-tasking kernel. This model is often used in smaller, less complex applications.

Is Linux Supported?

Yes. See PEG for Linux for a list of Linux distributions.

How much does a PEG Pro License cost?

The cost of a PEG Pro license depends on the type of license purchased. To receive current pricing information contact Sales. For license information, see Licensing.

What is the PEG Pro footprint size?

A minimum PEG Pro footprint requires roughly 220K of code space, 4K of stack, and 2K of dynamic memory. A typical full-featured PEG Pro GUI requires roughly 240K of code space, 4K of stack, and 8K of dynamic memory.
