Many 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.
Original Equipment Manufacturers (OEMs) can develop a common modem platform across multiple silicon suppliers.
Semiconductor platform vendors can separate 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 wireless modem and protocol stack design in standards such as GSM, 3G, HSPA and LTE.
The system diagram shows each product in context. Layer1 control and Physical Layer data processing is carried out by the Modem Compute Engine (MCE), supported by the Software Defined Modem Operating System (SDMOS).
MCE is a generic computing platform, which means that implementation of each RAT is purely a software development task. The multi-processor architecture uses three different types of processing element to execute the control thread, the real-time PHY sequencing and the actual PHY signal processing.
Development of the modem itself is supported by the SDM Development Environment, 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.
