LINUX STPC ATLAS DRIVER

The platform HAL can override this definition if necessary. It should never be necessary to load this package explicitly. Chipset support for two chipsets is open. The legacy BIOS specifications require parameter passing in registers rather than on the stack. An eCos configuration for an STPC Atlas-based platform should also include a platform HAL package to support board-level details like the nature of the external memory chips. Chipset modules for other parts can either be implemented by the user or licensed from PC Engines for a one-time fee.

Chipset modules qtlas other parts can either be implemented by the user or licensed from PC Engines for a one-time fee. The central processor is largely compatible and can run at up to MHz. When the variant HAL’s clock macros are enabled the package will also provide profiling timer support. It is intended for use in embedded systems.

The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can generate interrupts. Chipset modules are licensed for a one-time fee rather than a unit royalty. Your time is worth more than that. The platform HAL determines the default clock frequency, and can override any of these definitions if required.

An eCos configuration for an STPC Atlas-based platform should also include a platform HAL package to support board-level details like the nature of atlass external memory chips. Anyone may implement and publish their own chipset modules.

Automatically Tuned Linear Algebra Software (ATLAS)

Unloading the package should only happen as a side effect of switching target hardware. Features not needed or desired for embedded use have been left out.

Implementing this in C would be very cumbersome. I consider the CPL to be a flexible, well-written license. The BIOS core is less than lines of assembly code, very manageable.

Some are based on information that was provided to me by chip manufacturers under non-disclosure agreements.

In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers:. The legacy BIOS specifications require parameter passing in registers rather than on the stack. The package does not contain any configuration options. It should never be necessary to load this package explicitly. STPC Atlas registers can be accessed in a variety of ways.

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

The platform HAL can override this definition if necessary. Less code around lines – easier to understand and navigate.

The platform HAL can override these definitions if platform-specific macros are more appropriate. Access to source code means ease of adaptation and debugging.

In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers: Chipset support for two chipsets is open. Small size 16 to 32 KB means more space for your application.

This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption.

While ridiculously fast, it did have its limitations. No more ” keyboard failure – press F1 to continue ” errors.

It should be read in conjunction with similar sections from stc architectural and platform HAL documentation. Implementing new chipset modules requires more experience.
