F-04/06-0
corresponding Interrupt Mask Register bit has been set. At this
point, the library references a lookup table, which will then invoke
one of several specific user routines associated with specific
interrupt events. In responding to specific interrupt events, the
user routines may then invoke other library functions.
After a particular interrupt event has been responded to, the
thread will then perform a "manual" interrupt clear (if necessary).
At that time, the thread will then revert to its "blocking" condition.
This is all done internally by the library and driver to ensure reli-
ability. The user can optionally set up a user defined ISR by call-
ing the aceSetIrqConditions() function.
VXWORKS DRIVER
The BU-69090S2 is the Enhanced Mini-ACE API library with a C
language based VxWorks driver. This driver, which is designed to
operate with version 5.2 of Wind River's VxWorks, was devel-
oped using a Motorola MVME 2700 card, which is based on a
Power PC 750 processor. The drivers were developed using
Wind River's Tornado II integrated development environment.
The source code for the driver and library are provided to allow
the driver to be tailored to any specific host board. A version of
the software for Intel platforms is also included.
The driver makes the required calls to the operating system nec-
essary to acquire the correct address and interrupt resource
information. The driver will use these resources during initializa-
tion of the card, and for read, write, and interrupt functions dur-
ing normal operation. The ability to establish configuration in this
manner enables a hands-off configuration of the card in any sys-
tem.
LINUX DRIVER
The BU-69090S1 is the Enhanced Mini-ACE API library with a C
language based Linux driver. This driver is a loadable module
with source code available so that the driver can be compiled
against your version of the Linux kernel source code. This allows
for compatibility with any kernel version.
INTEGRITY DRIVER
The BU-69090S5 is the Enhanced Mini-ACE API Library with a
C language based Integrity driver. The driver is designed to oper-
ate with Power PC hosts.
OFFLINE DEVELOPMENT ENVIRONMENT
The software includes support of an offline development envi-
ronment (reference FIGURE 5). This allows code to be devel-
oped using a BU-65569 PCI card or BU-65553 PCMCIA card on
an offline workstation such as a desktop PC, rather than on
embedded system hardware. The Enhanced Mini-ACE library
includes a function that creates two files that download into the
application program for the target embedded system. The first file
is a binary file that contains an image of Enhanced Mini-ACE
registers and memory, and the second file is a C header file that
indicates all locations to structures/frames within memory.
The Enhanced Mini-ACE API library can also be programmed
without the need of an Enhanced Mini-ACE card. In simulated
access mode the library allocates host memory to be used as if
it were memory on the device. All application code can be devel-
oped before you actually receive hardware. Files can also be cre-
ated to allow the programmer to recreate the setup inside of an
embedded system.
The binary image file is stored in the embedded system non-
volatile memory. During initialization, it is then loaded into the
Enhanced Mini-ACE shared RAM and registers. The header file
contains a readable ASCII representation of the entire mapping
of the Enhanced Mini-ACE based on the operations entered into
the program. The header file includes the location and size of
message blocks and other data structures.
The benefits of the use of image and header files include: (1)
reduction in the size of embedded code; (2) reduced computa-
tional resources (CPU bandwidth cycles); and (3) the user has
greater control over the development, validation, and documen-
tation of flight critical and mission critical code.
