Abstract:
1. A modem device for use in a wireless communication terminal, the modem device comprising: a plurality of functional units configured to perform signal processing tasks, wherein: said plurality of functional units are connected in a ring structure; each of the functional units comprises a plurality of sub-components including a local processor, a plurality of hardware accelerators and further comprises a switching matrix connected between a data input of a respective functional unit and each of said sub-components; said local processor configured to receive task instructions from a controller of the modem device over a first bus system using a first protocol which includes addressing and an advanced high-performance bus (AHB) based protocol and, in response to said task instructions, arranged to configure the sub-components and configured to switch the switching matrix to selectively produce connections between said data input and said sub-components in a manner to perform said task; and wherein data flow in said ring structure between said functional units and within each functional unit is performed using a second protocol without addressing, said second protocol further configured to have three binary signals including a valid and an accept signal for handshaking between a data source and a data sink, and a frame signal which marks a beginning and an end of a logical group of data elements within a data stream.
