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 Texas Instrument C3x/C4x +architecture dependencies in this port of RTEMS. The C3x/C4x +family has a wide variety of CPU models within it. The following +CPU model numbers could be supported by this port: + +@itemize +@item C30 - TMSXXX +@item C31 - TMSXXX +@item C32 - TMSXXX +@item C41 - TMSXXX +@item C44 - TMSXXX +@end itemize + +Initiially, this port does not include full support for C4x models. +Primarily, the C4x specific implementations of interrupt flag and +mask management routines have not been completed. + +It is highly recommended that the RTEMS application developer obtain +and become familiar with the documentation for the processor being +used as well as the documentation for the family as a whole. + +@subheading Architecture Documents + +For information on the Texas Instruments C3x/C4x architecture, +refer to the following documents available from VENDOR +(@file{http//www.ti.com/}): + +@itemize @bullet +@item @cite{XXX Family Reference, Texas Instruments, PART NUMBER}. +@end itemize + +@subheading MODEL SPECIFIC DOCUMENTS + +For information on specific processor models and +their associated coprocessors, refer to the following documents: + +@itemize @bullet +@item @cite{XXX MODEL Manual, Texas Instruments, PART NUMBER}. +@item @cite{XXX MODEL Manual, Texas Instruments, PART NUMBER}. +@end itemize + |
