However, the nature of real-time systems makes +it essential that the application designer understand certain +processor dependent implementation details. These processor +dependencies include calling convention, board support package +issues, interrupt processing, exact RTEMS memory requirements, +performance data, header files, and the assembly language +interface to the executive. + +This document discusses the ARM architecture dependencies +in this port of RTEMS. The ARM family has a wide variety +of implementations by a wide range of vendors. Consequently, +there are 100's of CPU models within it. + +It is highly recommended that the ARM +RTEMS application developer obtain and become familiar with the +documentation for the processor being used as well as the +documentation for the ARM architecture as a whole. + +@subheading Architecture Documents + +For information on the ARM architecture, +refer to the following documents available from Arm, Limited +(@file{http//www.arm.com/}). There does not appear to +be an electronic version of a manual on the architecture +in general on that site. The following book is a good +resource: + +@itemize @bullet +@item @cite{David Seal.
