It should be read in conjunction with similar sections from the architectural and platform HAL documentation. The package does not contain any configuration options. Implementing new chipset modules requires more experience. 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. It is designed for easy adaptation and simple code. It is intended for use in embedded systems. This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption.

STPC Atlas registers can be accessed in a variety of ways. The legacy BIOS specifications require parameter passing in registers rather than on the stack.
STMicro announces latest x86 System-on-Chip devices
In an attempt to reduce confusion various suffixes are used, and in some cases utility macros are provided to access the registers: Features not needed or desired for embedded use have been left out. The platform HAL determines the default clock frequency, and can override any of these definitions if required.
It should never be necessary to load this package explicitly. Implementing new chipset modules requires more experience. It is intended for use in embedded systems.
PC Engines tinyBIOS open source BIOS for embedded PC
It should be read in conjunction with similar sections from the architectural and platform HAL documentation. The central processor is largely compatible and can run at up to MHz.
Chipset support for two chipsets is open. I will gladly refer customers to them, or add them to the open source code base. The platform HAL can override these definitions if platform-specific macros are more appropriate.
Not recommended for new designs – please consider coreboot as atlaas alternative. A is the closest replacement I could find, easy to get through www.
Automatically Tuned Linear Algebra Software (ATLAS)
The BIOS core is less than atpas of assembly code, very manageable. Your time is worth more than that. It is up to the platform HAL to define the interrupt vector numbers. This macro executes a hlt instruction, suspending the CPU until the next interrupt and thus reducing power consumption.
The implementation uses the processor’s PIT0 timer since that is the only on-chip timer which can generate interrupts. The implementation of other parts of the HAL specification is unaffected, and no additional functionality is provided. The tspc HAL can override this definition if necessary. When the variant HAL’s clock macros are enabled the package will also provide profiling timer support. The package does not contain any configuration options. In an attempt to reduce confusion various suffixes are ,inux, and in some cases utility macros are provided to access the registers:.
Some are based on information that was provided to me by chip manufacturers under non-disclosure agreements. While ridiculously fast, it did have its limitations.
I consider the CPL to be a flexible, well-written license. Less code around lines – easier to understand and navigate. Anyone may implement and publish their own chipset modules.
Chipset modules for other parts can wtpc be implemented by the user or licensed from PC Engines for a one-time fee. Access to source code means ease of adaptation and debugging.
Chipset modules are altas for a one-time fee rather than a unit royalty. No more ” keyboard failure – press F1 to continue ” errors. Small size 16 to 32 KB means more space for your application.
