Modem Hardware Abstraction Layer (MHAL)
Support for MHAL Application Programming Interfaces on the SDR-4000

Spectrum now offers early support for the U.S. Joint Tactical Radio System’s (JTRS) Modem Hardware Abstraction Layer (MHAL) Application Programming Interfaces (API) on its SDR-4000 products for qualified customers. The MHAL API was designed specifically to enhance portability of waveform components and radio applications operating on specialized processing devices such as Field Programmable Gate Arrays (FPGAs) and Digital Signal Processors (DSPs).

The U.S. Joint Program Executive Office (JPEO) for the JTRS program announced the release of the MHAL API on June 6, 2007. The MHAL API abstracts the modem hardware and radio Operating Environment from the waveform applications to provide a consistent waveform host environment across the Software Communications Architecture (SCA)-compliant platforms. The SCA itself is an open specification sponsored by the U.S. Department of Defense JTRS program that standardizes the deployment, management, interconnection and intercommunication of software application components in embedded, distributed-computing communication systems. The SCA specifies software, hardware, security, and networking architecture requirements for open, programmable SDR systems with flexible, re-programmable communication capabilities.

The MHAL API Library Support for SDR-4000 is available to qualified customers as an optional software package. Please contact Spectrum for pricing and further information.
