6U Boards
The 6U LightningBolt board provides all the resources required to
obtain optimal
performance from SKY’s compute and I/O modules. It is
configured with one
compute module of four MPC7448 processors.
Data is transferred throughout the LightningBolt over the SKYchannel
Packet
Bus at 320 MB/sec. Data moves transparently through the SKYchannel P2
interface to other boards in a SKYchannel chassis. System control is
handled by
the System Processor, which performs I/O and operating system tasks
that would
otherwise burden the compute processors. A full VME64 interface
provides
communication to the host and other off-board communication. The
application
runs on the processors resident on the compute module. Front-panel I/O
expansion modules may be added to the LightningBolt for maximum I/O
performance.
LightningBolt uses the 1.2 GHz PowerPC
MPC7448 microprocessor and the ANSI/VITA
standard SKYchannel interconnect fabric, delivering
optimal computing and I/O performance.
The advanced SKYvec® software development
environment provides tools that simplify complex
multiprocessor programming. The 6U
LightningBolt is configured with one compute
module of four MPC7448s and one optional I/O
module.
The new LightningBolt embedded computers are
100 percent compatible with SKY’s previous
SKYbolt® family of products. Customers can
easily upgrade to LightningBolt without re-writing
their applications.

System Processor: Offloading System-Level Functions
The LightningBolt employs a System Processor (SP) to off-load
system-level
functions from the compute processors. At its core is an Intel
i960HD™ superscalar
processor. SKY adds 2 MB SRAM used as zero-wait-state RAM and 16
MB Flash RAM for non-volatile storage of configurable boot code. The large
flash memory of the SP provides a Self Boot capability for the
LightningBolt
Compute Module which results in 10 second Fast Boot for start up and
initialization.
On power-up, the software monitor, kernel, and application are loaded
into the
working memory of the SP and the compute modules. Because the SKY
boards
all boot in parallel, the SKY fast boot capability allows an entire
16-board, 64-
processor system to start a typical SAR application in 10 seconds
instead of the
up to 10 minutes for systems without parallel boot capability. This is
key in realtime
mission-critical applications, where the length of time in the start or
re-start
of a system can mean missing a potential threat or target. It also
saves time in
development environments which normally require multiple boots while
debugging.
