Version 1.0.G1.0f                                           February 15, 1994
*****************************************************************************

First release of Nucleus PLUS for ARM60 using the ARM development tools.

Version 1.1.G1.1                                               March 18, 1994
*****************************************************************************

The following items were changed or corrected by this release:

        .       Components broken into multiple files to reduce 
                instruction area memory requirements.

        .       Added NU_DEBUG conditional compilation flag 
                that maps the NU data structures (NU_TASK, 
                NU_QUEUE, etc.) to the actual internal data 
                structures.  This allows the user to examine 
                (with a source-level debugger) the actual 
                contents of each system object.  If used, all
                PLUS and applicable application files should 
                be compiled with this symbol defined.

         .      Added NU_INLINE conditional compilation flag 
                to replace some linked-list processing with 
                inline code.  This may be applied to any or 
                all PLUS files.

         .      Mailbox, queue, and pipe message copying was
                optimized.

         .      Simplified internal protection logic to increase
                performance in suspend and resume task threads.

         .      Added NU_Local_Interrupt_Control and 
                NU_Restore_Interrupts service calls.

         .      Fixed a problem in time-slice logic that could 
                result in a system crash.

         .      Fixed a problem in the error checking functions 
                for NU_Resume_Task and NU_Resume_Driver that could
                result in permanent task suspension.

         .      Fixed a problem in timer management that could 
                cause a loss of a tick in some task sleep, task 
                timeout, and application timer requests.

         .      Fixed a problem in task terminate/timeout 
                processing that could result in a system crash.

         .      Fixed a problem in queue and pipe reset logic.

         .      Fixed a problem in NU_Control_Interrupts function.

         .      Fixed a problem in TCT_Unprotect_Specific function.

All files have been updated for this release of Nucleus PLUS.

The following items were changed or corrected by this release:

                Corrected ARM bug in TMT.S which had to do with the
                calling the new TMT_Adjust_Timer routine with the 
                referance to the TMD_Timer variable.

The following items were changed or corrected by this release:

        1) NUCLEUS.H - NU_Mailbox_Pointers is not prototyped. (SPR40)

        2) NUCLEUS.H - NU_Current_HISR_Ptr is incorrectly mapped 
                       when error checking is turned on. (SPR51)

        3) TMT.S - In TMT_Timer_Adjust, corrected a problem where a created
                   timer would never time out. (SPR79)

Nucleus PLUS generic version 1.2.

-  PICE.C       Corrected bug in PICE_Receive_From_Pipe where variable size
                pipes where being treated liked fixed size pipes. (SPR65)

-  TCC.C        Corrected bug in TCC_Resume_Service where "task" parameter in
                the HIC_Make_History_Entry call should be "task_ptr". (SPR36,
                SPR64, SPR66, SPR77)

-  TCCE.C       Enhanced TCCE_Task_Sleep where we now return if a sleep time
                value of 0 or less is passed in. (SPR37)

-  TCS.C        Corrected bug in TCS_Send_Signals where the tc_enabled_signals
                mask was not being checked before trying to execute the signal
                handler. (SPR107)

-  TMC.C        Corrected numerous timer problems. (SPR52)

-  RLD.C        Updated Release string to represent Generic 1.2 release.

-  TC_EXTR.H    Corrected a typo in the function prototype for
                INT TCT_Control_Interrupts(INT new_level); (SPR??)
