Embodiment Construction

[0020] Turning now to FIG. 1, it shows a block diagram of one embodiment of a multimode wireless communication device including a programmable baseband processor. In the illustrated embodiment, some basic parts of a radio communication system are shown from a functional and hardware perspective. More specifically, the multi-mode wireless communication device 100 includes a receiving subsystem 110 and a transmitting subsystem 120, both of which are coupled to one or more antennas 125. Note that in various embodiments, the multi-mode wireless communication device may be a handheld mobile phone device or the like. Note also that elements having reference identifiers including numbers and letters may suitably be indicated by numbers only.

[0021] The receiving subsystem 110 includes a part of an RF front end 130 coupled between an antenna 125 and an analog-to-digital converter (ADC) 140. The ADC 140 is coupled to a programmable baseband processor (PBBP) 145A, and the programmable bas...

Abstract

A programmable digital signal processor including a clustered SIMD microarchitecture includes a plurality of accelerator units, a processor core and a complex computing unit. Each of the accelerator units may be configured to perform one or more dedicated functions. The processor core includes an integer execution unit that may be configured to execute integer instructions. The complex computing unit may be configured to execute complex vector instructions. The complex computing unit may include a first and a second clustered execution pipeline. The first clustered execution pipeline may include one or more complex arithmetic logic unit datapaths configured to execute first complex vector instructions. The second clustered execution pipeline may include one or more complex multiplier accumulator datapaths configured to execute second complex vector instructions.

Description

Technical field [0001] The invention relates to a digital signal processor, and more specifically, to a programmable digital signal processor microarchitecture. Background technique [0002] In a short period of time, the use of wireless devices, especially mobile phones, has increased significantly. This worldwide growth of wireless devices has led to the convergence of a large number of emerging radio standards and wireless products. This in turn has also aroused increasing interest in Software Defined Radio (SDR). [0003] As stated in the SDR Forum, SDR is a collection of hardware and software technologies that can implement reconfigurable system structures for wireless networks and user terminals. SDR provides an effective and relatively inexpensive solution to the problem of establishing multi-mode, multi-band, and multi-function wireless devices that can be enhanced by software upgrades. Therefore, SDR can be regarded as an enabling technology that can be applied in a wide...
