Embedded Systems
Gunn systems has extensive experience in developing embedded control systems.
We have a
broad base of experience, from simple single-threaded
systems to complex multi-threaded systems. We can take your product
from specification to prototype to manufacturing quickly and efficiently.
Gunn Systems
has the unique advantage of "bridging the gap"
between hardware and software. We have staff with experience in hardware design and software
applications. This experience allows us to develop embedded systems
firmware/software that has the best possible trade-offs between hardware
and software control. We can also recommend the best fit for off-the-shelf
hardware or custom-designed hardware.
Gunn Systems
also has experience with embedded Linux solutions. Linux is an excellent
option for complex embedded system designs that need multiple threads
and processes. Gunn Systems has been developing embedded Linux solutions
for more than four years (far longer than most embedded systems developers).
For simpler
systems that do not require the extensive services and power of an operating
system, Gunn Systems offers a simple, executive-based system for small
processor type systems.
Our expertise
in embedded systems includes:
- Languages
such as C, C++ and Assembly.
- Real
time operating systems and executives.
- Embedded
Linux solutions.
- Utilizing
in-house development platforms and emulators.
- Debugging
and testing, including hardware simulation.
- Network
and serial communications.
- Interface
to communications equipment.
- Interface
to computer applications via custom
programming services.

and GSI-2 Controller section for information

Embedded
Platforms
Although
Gunn Systems has a variety of experience in many types of embedded platforms,
we often find these platforms meet most customer needs:
| |
|
| |
Gunn
Systems GSI-2 Platform. - The Gunn Systems' GSI-2 is an open-source
embedded control board, a PLC (Programmable Logic Controller) with
built-in sensors and an X10 interface. See the GSI-2
section for more information on GSI-2 hardware and software capabilities
and options. |

|
| |
Freescale Semiconductor
68HC11 Platforms. - The Freescale 68HC11 processor offers excellent
performance for small and low budget embedded systems applications.
Gunn Systems has used several 68HC11-type embedded systems (see Links
below) to meet stringent project budget and time requirements. We
find this processor offers more capability than PIC based designs
for comparable costs. We often recommend the Axiom CMM11E1 (pictured
above) with the Gunn Systems Expansion Module because of its price
and performance. |

|
| |
Embedded
PC Platform. - The Embedded PC platform (PC-104, or single board
ISA/PCI computers) is an excellent platform choice when performance
is a must. Leveraging the PC industry's cost-to-performance benefits,
this platform offers the most bang for the buck. With this platform,
we can offer embedded Linux for situations where an operating system
with networking and other facilities are required. For simpler embedded
system design, we use the TICS real-time operating system for low
cost and simple needs. A variety of hardware is available for implementing
an embedded system using off-the-shelf PC hardware. |
Examples
of Solutions Provided
These are
just a sampling of the Embedded Solutions that Gunn Systems has provided:
| |
Tank
Monitoring System |
Firmware
and Hardware for monitor and control system for storage tanks. Written
using 68HC11 C and Assembly. Developed from specification into low
volume manufacturing. |
| |
Sign
Control Firmware & Hardware |
Firmware
for controlling large overhead variable message signs on highways.
This was a complex design that used a real time operating system on
an embedded PC platform. Written using C for an embedded PC application
(80286). Uses the TICS real-time operating system. Hardware was off-the-shelf
PC hardware integrated with Gunn Systems Developed custom hardware. |
| |
Enclosure
Management Controller Firmware |
Firmware
for controlling disk drive enclosures. The firmware was written using
the 6502 instruction set using C and assembly for an embedded system
on a chip. This project was done for a product sold by a major semiconductor
supplier! Firmware was hand-optimized for speed and memory requirements.
This firmware had SCSI and I2C interfaces. |
|
Specialized Inkjet Printer Hardware & Firmware |
Developed
a working prototype of an Inkjet printing device for painting fingernails.
Gunn Systems worked closely with the startup company and hit the
required target budgets and time schedules to build working prototypes
for market analysis. We assisted in-house staff with the software
and technical issues faced by the introduction of a new product
by a startup company.
The system involved design and development of an embedded system
using the 68HC08 microprocessor to drive a proprietary printing
platform. Gunn Systems developed the Hardware, PC Board, and Firmware
programming to control the printer.
