• Description: SC100 Application Binary Interface Reference Manual
• Manufacturer: Motorola / Freescale Semiconductor

This manual defines the SC100 Application Binary Interface (ABI). The ABI is a set of interface standards
that writers of compilers, assemblers, and debugging tools must use when creating tools for the SC100
architecture. These standards cover run-time aspects as well as object formats to be used by compatible
tools chains. The standard definition ensures that all SC100 tools are compatible and can interoperate.
Although compiler support routines are provided, this manual does not describe how to develop SC100
tools, nor does it define the services provided by an operating system or a set of libraries. These
components must be defined by tools, libraries, and operating system suppliers.
1.1 Purpose
The standards defined in this manual are intended to ensure that all development tool chains for the SC100
architecture are fully compatible. This ensures that the tools can interoperate, thus making it possible to
select the best tool for each component of the application development tools chain. The standards in this
manual also ensure that compatible libraries of binary components can be created and maintained.
Developers can build up libraries over time with the assurance of continued compatibility.
