Unloading the package should only happen as a side effect of switching target hardware. In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers: Not recommended for new designs – please consider coreboot as an alternative. Less code around lines – easier to understand and navigate. I consider the CPL to be a flexible, well-written license.

The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can generate interrupts.
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. The platform HAL can override these definitions if platform-specific ilnux are more appropriate. It should be read in conjunction with similar sections from the architectural and platform HAL documentation.
Anyone may implement and publish their own chipset modules. 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.

Implementing this in C would be very cumbersome. Access to source code means ease of adaptation and debugging. Less code around lines – easier to understand and navigate. Chipset support for two chipsets is open.
The BIOS core is less than lines of assembly code, very manageable. No more ” keyboard failure – press F1 to continue ” errors. STPC Atlas registers can be accessed in a variety of ways. When the variant HAL’s clock macros liux enabled the package will also provide profiling timer support.
Your time is worth more than that.
Some are based on information that was provided linnux me by chip manufacturers under non-disclosure agreements. It should never be necessary to load this package explicitly.
I will gladly refer customers to them, or add them to the open source code base. Small size 16 to 32 KB means more space for your application.
It is intended for use in embedded systems. The central processor is largely compatible and can run at up to MHz. The implementation of other parts of the HAL specification is unaffected, and no additional functionality is provided. 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.
Not recommended for new designs – please consider coreboot as an alternative. A is the closest replacement I could find, easy to get through www. While ridiculously fast, it did have its limitations.

Chipset modules for other parts can either be implemented by the user or licensed from PC Engines for a one-time fee. It is designed for easy adaptation and simple code.
Chipset modules are licensed for a one-time fee rather than a unit royalty. This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption. The platform HAL can override this definition if necessary. The package does not contain any configuration options.
I consider the CPL to be a flexible, well-written license. Unloading the package should only happen as a side effect of switching target hardware.
