LINUX STPC ATLAS DRIVER

The implementation of other parts of the HAL specification is unaffected, and no additional functionality is provided. Not recommended for new designs – please consider coreboot as an alternative. The legacy BIOS specifications require parameter passing in registers rather than on the stack. Some are based on information that was provided to me by chip manufacturers under non-disclosure agreements. Implementing this in C would be very cumbersome. The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can generate interrupts. Features not needed or desired for embedded use have been left out.

In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers:. This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption.

Embedded PC platforms

An eCos configuration for an STPC Atlas-based platform should also include dtpc platform HAL package to support board-level details like the nature of the external memory chips. It is intended for use in embedded systems. Not recommended for new designs – please consider coreboot as an alternative.

Access to source code means ease of adaptation and debugging. Your time is worth more than that. Chipset modules are licensed for a one-time fee rather than a unit royalty.

Qtlas BIOS core is less than lines of assembly code, very manageable. A is the closest replacement I could find, easy to get through www. STPC Atlas registers can be accessed in a variety of ways.

Anyone may implement and publish their own chipset modules. The platform HAL determines the default clock frequency, and can override any of these definitions if required.

It is up to the platform HAL to define the interrupt vector numbers.

In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access linuc registers: The package does not contain any configuration options. The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can ,inux interrupts.

I consider the CPL to be a flexible, well-written license. The platform HAL can override this definition if necessary. Small size 16 to 32 KB means more space for your application.

ZXE-ST586/104P

The legacy BIOS specifications require parameter passing in registers rather than on the stack. Features not needed or desired for embedded use have been left out.

The platform HAL can override these definitions if platform-specific macros are more appropriate.

Chipset modules for other parts can either be implemented by the user or licensed from PC Engines for a one-time fee.

The implementation of other parts of the HAL specification is unaffected, and no additional functionality is provided. When the variant HAL’s clock macros are enabled the package will also provide profiling timer support. Implementing this in C would be very linuux.

No more ” keyboard failure – press F1 to continue ” errors. Implementing new chipset modules requires more experience. It should never be necessary to load this package explicitly. The central processor is largely compatible and can run at up to MHz.

It should be read in conjunction with similar sections from the architectural and platform HAL documentation. I will gladly refer customers to them, or add them to the open source code base. While ridiculously fast, it did have its limitations. Some are based on information that was provided to me by chip manufacturers under non-disclosure agreements.
