DSP Firmware/Software Development
AISD, Inc. provides consulting services to develop DSP firmware for audio
processing, telephony and wireless modem designs and other DSP related
tasks, such as frequency synthesis, control and regulation systems, recognition
systems, and so forth.
Key Benefits
Allows your company to develop DSP product without a staff of DSP developers.
Quality design and verification by staff of highly qualified personnel
with both hardware and software background. On time delivery with specified
schedule and cost predictions ahead of project commencement.
Capabilities
AISD can plan and specify the product providing documentation for the
design implementation. Then the implementation will be done based on the
schedule provided in the plan. Finally, the product testing is completed.
We do not throw designs over the wall. We are with you until you have
a successful product.
Planning and Specification
AISD can be contracted to perform a study and planning phase for a product
development. Generally this is necessary so that the development work
to be completed can be agreed upon with the customer to their satisfaction.
Design Implementation Development During this phase of the development,
AISD will provide the detailed implementation of the design.
Cooperative Design Partnerships
AISD can be contracted as a design partner in your system development.
In some cases where the client knows of the need, but does not have the
staff to develop it into a product, we can form a design partnership.
This can have the impact of reducing your up front development costs for
a new product, in exchange for a sharing arrangement in the success of
the product after it goes into production. In situations like this, we
will do a market analysis together with the client to develop an agreement
regarding the future value of the product. We welcome serious opportunities
of this nature.
Test and Verification
Most of the time, there is a hardware environment on which the firmware
development must be verified. This can be a standard environment of a
customer specific one. Our task at this point is the hardware/firmware
integration. Generally we work closely with the customer during this phase
to complete the product.

Single Chip 2400 baud modem firmware
 AISD, Inc. worked together with a major silicon vendor to produce
the cheapest single chip 2400 baud modem. AISD, Inc. assisted in the development
of the DSP architecture used in the IC, and we also developed the data
pump firmware that does the modem math in code within the processor. AISD,
Inc. worked together with this customer through testing and certification.
This IC is one of our clients highest selling products.
Jitter Attenuator
Under contract with major semiconductor vendor, AISD, Inc. developed
a Jitter Attenuator IC for use on T1 and other high speed com links.
We
developed a model for the part, and then prototyped the digital section
of the part in an FPGA. The client added their analog front end and
produced
a DSP based jitter attenuator product that ius produced in high volume.
RF Network (RFN) - RF Propagation Simulator
Under government sub-contract, AISD, Inc. is developing an RF propagation
simulator that allows the US Navy to test JTIDS terminals and navigation
equipment in the lab simulating distance related attenuation and
delay as would be experienced in a dynamic combat scenario. This project
also included development of a Windows GUI to interact with the RFN
and with
a script controller over the network. This test equipment
is in use in the US Navy SPAWAR System Integration Facility (SIF) in
San Diego,
California. We are currently developing a
follow-on system to support JTRS radios (2MHz - 2GHz).
Digital Power Supply Controller
AISD, Inc. has worked together with a major developer of power supply
controller ICs in the development of small digital PWM controller
ICs used
in cell phone chargers, laptop power supply assemblies, and so forth.
Working with the client, AISD
developed the DSP code firmware/hardware in these IC's.
We also participated in the development of the control algorithms used
in those chips, as well as the IC implementation. These ICs are sold
in high volumes, and lead the industry in terms of efficiency, small
size, and total cost of ownership.
Custom Measurement While Drilling Communications Modem
Under contract with a national drilling pipe manufacturer, AISD,
Inc. developed a mathmatical model for the client's specialized media
(modified drill pipe), and
then designed a modem
to communicate over that media at up to 2 Mbits/sec. We implemented a
cycle-accurate C model with channel simulator to verify operation and
BER in the presence of noise and other impairments, then converted it
to synthesizeable Verilog. AISD, Inc. developed the TDMA Full Duplex
protocol
for
the
system that
included
the facility for time synchronous recording. We developed several working
prototypes for the final IC (approx 75k gates) using a Xilinx FPGA and
discrete
analog
circuits (VGA, carrier detect, TX/RX switch) with ADC's and DAC's.
AISD, Inc. also developed the board level products
for the first and second
level
prototypes
for
this
system, as well as GUI data collection and processing software. These
boards were used downhole in test wells, collecting accelerometer and
temperature data. |
