Wintegra is offering a family of single chip processors and associated software for WiMAX basestation applications.
Designed to be used in picostations and multi-sector macro basestations supporting advanced features such as adaptive antenna system (AAS) and MIMO, the device can be customised to support newer standards such as wav-2, 16j relay stations, 16h for unlicensed frequency bands and the 16m next generation mobile network standard.
The WinMax processor itself is based on the recently introduced WinPath2 family of processors, which utilizes the same data path software (DPS) and WDDI API software architecture as the company’s successful WinPath1 processors.
This datapath engine architecture is based on Symmetric Multi Thread Processor (SMTP) technology. It offers market leading density in terms of the number of sectors and subscribers per sector that can be supported. Up to 4 MAC instances can be accommodated on a single part.
“We intend to support the WinMAX system with a series of reference platforms that will reduce development time and thus improve time-to-market,” said Colin Alexander, director of wireless marketing at Wintegra.
The design incorporates a software suite of DPS modules that provide the user with a suite of low level (typically Layer 2 - 4) protocol and interworking implementations. DPS executes on a series of custom-designed RISC processor cores – collectively called WinComm – and are accessible from the on-chip host processor through a software API called the WinPath Device Driver Interface (WDDI).
This architecture allows the control and data path functions to be integrated on the same device, with the host device handling termination and management functions, and the WinComm engine handling the switching, interworking, or backplane data path functions from the line interface.
