Products

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 Modem Compute Engine, supported by
the Software Defined Modem Operating System (SDM-OS).
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 the SDM Design Envirnoment, consisting of 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, optimised PHY Kernel Libraries are available to support several RAT standards.
