Abstract:
1. An architecture for a SDR communications system, comprising: a plurality of processors, a switching fabric comprising a plurality of nodes, each of said nodes comprising at least one switching element associated with at least one of said processors; said plurality of nodes connected to one another in a grid; wherein: said nodes comprise a distinct set of Software Defined Radio Processor (SDRP) blocks controlled by software; each of said SDRP blocks from said set connected to another neighboring SDRP block from said set, said SDRP blocks are connected to substantially identical SDRP blocks from said set along said North-South direction and connected to substantially different SDRP blocks from said set along said East-West directions, said SDRP blocks comprise a Modem Block having circuitry to convert a sampled analog signal into digital baseband data; a Black Block having a processor that processes data received by said Black Block that is encrypted, a Red Block having a processor that processes data received by said Red Block that is sensitive data that must be encrypted; a Crypto Block having circuitry to encrypt data received by said Crypto Block, using cryptographic algorithms, the Crypto Block has ports along said North-South direction and ports along said East-West direction, said Crypto Block disposed between said Red block and said Black Block and communicating with said Red and Black Blocks along said East-West direction via said East-West ports, and communicating with another plurality of adjacent Crypto Blocks along said North-South directions via said North-South ports; and, said Crypto Block is comprised of a Black Block and a Red Block operatively joined together and communicating with one another; and, the Black and Red Blocks each have ports along said North-South direction and ports along said East-West direction; said Black and Red Blocks topologically adjacent to at least one other Black and Red Block; said Black and Red Blocks communicating with neighboring SDRP blocks according to the following: Black Blocks communicate with adjacent neighboring Black Blocks via said North-South Black ports; Red Blocks communicate with adjacent neighboring Red Blocks via said North-South Red ports; Black Blocks communicate with at least one of said Modem Blocks, Red Blocks and Crypto Blocks via said East-West Black ports; and Red Blocks communicate with at least one of said Modem Blocks, Black Blocks and Crypto Blocks via said East-West Red ports.
