Problems solved by technology

[0004] Computing the product sum or scalar product of two data vectors is a typical application of this type of signal processor, for example, when computing autocorrelation functions and cross-correlation functions, or when processing digital signals with FIR filters, when the algorithm requires many In the case of calculation time and real-time execution, for example, in digital mobile radios, the calculation speed of the signal processor of the prior art cannot meet the requirements, by connecting another data processing unit in parallel and the other unit is passed through an additional The method of data bus to obtain data to increase the calculation speed requires a lot of circuits and costs

Embodiment Construction

[0019] figure 1 The signal processor has a bus system 1 to which a plurality of functional units are coupled. A bus system has buses for transferring data, addresses and transferring signals. For example, the bus system 1 has a data bus system and a program bus which will not be described in detail here, and the addressing unit 2 provides addresses to the memory unit 3 to read out relevant storage contents. The storage unit 3 is generally made of ROM and / or RAM, and then first and second data processing units 4 and 5 are provided here, which are used to process the data read out by the storage unit 3, and the processing unit 5 is not directly connected A data bus system to the bus system 1, but receiving data via the first data processing unit 4, the program storage unit 6 is connected to the units connected to the bus system 1 via the program bus.

[0020] Furthermore, a peripheral unit 7 is connected to the bus system 1, which unit has input and output units. Connected to...

Abstract

The invention relates to a signal processor having a first data processing unit (4) with means for processing data by means of arithmetic or logic operations, and to a radio transceiver having such a signal processor. For the purpose of increasing the computing speed, it is proposed, in particular when calculating autocorrelation functions or cross-correlation functions or in the case of digital filtering using FIR filters, to provide at least one further data processing unit (5), which operates in parallel with the first data processing unit (4) and has means (17, 18, 19) for processing, by means of arithmetic or logic operations, data which are derived from the data supplied to the first data processing unit (4).

Description

technical field [0001] The invention relates to a first signal processor comprising a data processing unit comprising processing means for processing data by means of arithmetic or logical operations, the invention also relates to a transceiver comprising a signal processor , the signal processor includes a data processing unit with processing means to process data through arithmetic or logic operations. Background technique [0002] The radio transceiver for the vehicle implements complex algorithms to process speech in real time, generally a signal processor is used for this purpose, another possible technical solution is to use a special chip specially developed for this application, a signal processor Other areas of application are eg audio, video, medicine and automation technology. From by M.Kappelan and H.Mucke. Published Radio Magazine 16 / 1993, pages 66 to 69, entitled "Digital Signal Processors Part 1: Processors Fulfilling Special Requirements", it is possible to...
