+This directory contains a family of BSPs for the v850 simulator
+found in the GNU Debugger. A variant is provided for each CPU
+model option flag found in the GCC SVN head as of 30 May 2012.
+
+This simulator is an instruction simulator and does not include
+devices for a clock tick or benchmark timer driver. Traps are used
+to provide console I/O.

+ *     -# task level context stuff::  Context_Control
+ *     -# floating point task stuff:: Context_Control_fp
+ *     -# special interrupt level context :: CPU_Interrupt_frame

+ *  On some processors, it is cost-effective to save only the callee

+ *  persist across function calls.  It is not mandatory to make this

+ *  If the cost of saving extra registers is minimal, simplicity is the
+ *  choice.  Save the same context on interrupt entry as for tasks in

+ *  Additionally, if gdb is to be made aware of RTEMS tasks for this CPU, then

+ *  @a Priority_bit_map_Control.  This type may be either 16 or 32 bits
+ *  wide although only the 16 least significant bits will be used.
+ *
+ *  There are a number of variables in using a "find first bit" type
+ *  instruction.
+ *
+ *    -# What happens when run on a value of zero?
+ *    -# Bits may be numbered from MSB to LSB or vice-versa.
+ *    -# The numbering may be zero or one based.
+ *    -# The "find first bit" instruction may search from MSB or LSB.
+ *
+ *  RTEMS guarantees that (1) will never happen so it is not a concern.
+ *  (2),(3), (4) are handled by the macros @ref _CPU_Priority_Mask and
+ *  @ref _CPU_Priority_bits_index.  These three form a set of routines
+ *  which must logically operate together.  Bits in the _value are
+ *  set and cleared based on masks built by @ref _CPU_Priority_Mask.
+ *  The basic major and minor values calculated by @ref _Priority_Major
+ *  and @ref _Priority_Minor are "massaged" by @ref _CPU_Priority_bits_index
+ *  to properly range between the values returned by the "find first bit"
+ *  instruction.  This makes it possible for @ref _Priority_Get_highest to
+ *  calculate the major and directly index into the minor table.
+ *  This mapping is necessary to ensure that 0 (a high priority major/minor)
+ *  is the first bit found.
+ *
+ *  This entire "find first bit" and mapping process depends heavily
+ *  on the manner in which a priority is broken into a major and minor
+ *  components with the major being the 4 MSB of a priority and minor
+ *  the 4 LSB.  Thus (0 << 4) + 0 corresponds to priority 0 -- the highest

+@endverbatim

+ *      bit set

+@chapter V850 Specific Information
+
+This chapter discusses the
+@uref{http://en.wikipedia.org/wiki/V850,V850 architecture}
+dependencies in this port of RTEMS.  The V850 was originally manufactured
+by NEC but is now part of the Renesas Electronics product line.
+
+@subheading Architecture Documents
+
+For information on the V850 architecture refer to the
+@uref{http://am.renesas.com/products/mpumcu/v850/index.jsp,Renesas v850 product page}.
+
+@section CPU Model Dependent Features
+
+This section presents the set of features which vary across V850 implementations and are of importance to RTEMS.  The set of CPU model feature macros are defined in the file @file{cpukit/score/cpu/v850/rtems/score/v850.h} based upon the particular CPU
+model flags specified on the compilation command line.
+
+@subsection CPU Model Name
+
+The macro @code{CPU_MODEL_NAME} is a string which designates
+the architectural level of this CPU model.  See in
+@file{cpukit/score/cpu/v850/rtems/score/v850.h} for the values.
+
+@subsection Count Leading Zeroes Instruction
+
+The V850v5 and later has the count leading zeroes @code{clz} instruction which
+could be used to speed up the find first bit operation.  The use of this
+instruction should significantly speed up the scheduling associated with a
+thread blocking.  This is currently not used.
+
+@subsection Floating Point Unit
+
+A floating point unit is currently not supported.
+
+@section Calling Conventions
+
+Please refer to the
+@uref{http://www.filibeto.org/unix/tru64/lib/ossc/doc/cygnus_doc-99r1/html/6_embed/embV850.html,
+Procedure Call Standard for the V850 Architecture} or the GCC source
+code for detailed information on the calling conventions.
+
+@subsection Register Usage
+
+Fixed registers are never available for register allocation in the
+compiler. By default the following registers are fixed in GCC:
+
+@itemize @bullet
+@item r0 (zero)
+@item r3 (sp)
+@item r4 (gp)
+@item r30 (ep)
+@end itemize
+
+@c r1 is mentioned as special purpose but I do not see a purpose
+
+Caller saved registers can be used by the compiler to hold values that
+do not live across function calls. The caller saved registers are r2,
+r5 through r19, and r31.
+
+Callee saved registers retain their value across function calls. The
+callee saved registers are r20 through r29.
+
+r6 through r9 are parameter registers while r10 and r11 are function return registers. r31 is the return pointer.
+
+r29 is used as the frame pointer in some functions.
+
+@section Memory Model
+
+A flat 32-bit memory model is supported.  
+
+@section Interrupt Processing
+
+The V850 architecture has ...
+
+@subsection Interrupt Levels
+
+The RTEMS interrupt level mapping scheme for the V850 is very simple. If
+the requested interrupt level is 1, then interrupts are disabled in the
+PSW register using the @code{di} instruction. If the requested interrupt
+level is 0, then interrupts are enabled in the PSW register using the
+@code{ei} instruction or restoring the previous value of the PSW register.
+ 
+@subsection Interrupt Stack
+
+The board support package must initialize the interrupt stack. The memory for
+the stacks is usually reserved in the linker script. 
+
+@section Default Fatal Error Processing
+
+The default fatal error handler for this architecture performs the
+following actions:
+
+@itemize @bullet
+@item disables operating system supported interrupts (IRQ),
+@item places the error code in @code{r10}, and
+@item executes a halt processor instruction.
+@end itemize
