Our products enable developers of communications
enabled devices, such as cellphones, mobile internet
devices, access points and femtocells to realise a truly
software defined modem. This approach means that
Radio Access Technologies (RAT) may be combined in
a modular fashion to create highly efficient multimode
solutions which can be evolved without costly and
time-consuming silicon re-design.
The technology can be used by Original Equipment
Manufacturers (OEM) to develop a common modem
platform across multiple component suppliers; or
directly by semiconductor component developers as
a means of separating the complex modem design
cycle from the costly silicon design cycle.
At the heart of Cognovo’s products are two decades
of experience in highly parallel processor and tools
development, combined with modem and protocol
stack design in standards encompassing GSM, 3G,
LTE and TD-SCDMA.
The system overview diagram shows how each
product forms part of a complete system. Layer1 and
Physical Layer processing is carried out by the
L1PHY Compute Engine, supported by the L1PHY
runtime software, which together with the Protocol
Plane (P-Plane) processing subsystem and Protocol
Framework constitute a complete SoftModem Platform.
The modem hardware is a generic computing platform,
which means that implementation of the actual RAT
standard is purely a software development task.
Development of the modem is supported by two Software Development Kits (SDK) – one focused on Physical Layer kernels and a second focused on overall system design, integration and validation.
To ease development, low level run time software is provided for the control plane processor which is designed to support porting of existing layer 1 code. In addition, optimised PHY Kernel Libraries are available to support several RAT standards.
The Protocol Framework is an object oriented software framework to support modular multi-mode protocol stack development and is a complement to the software defined modem platform.
