Embodiment Construction

[0017] Figure 2A-2B A transformation of a system data flow 200, 200' according to an example of the invention is shown. Figure 2A The example dataflow 200 shows that input INa 201 may be processed by various functional units F1 - F4 210 - 240 to produce output Q 209 . Functional elements F1-F4 may represent any of the various functions. In the context of a digital television system such as that shown in Figure 1, functional blocks F1-F4 may represent individual blocks in a channel decoder that use feedback through F4 to modify the characteristics of filter F1. In this example, block F2 may be a demodulator, and block F3 may extract a parameter from the demodulated signal to provide feedback to block F4.

[0018] As technology advances and new features and capabilities become acceptable, the data flow 200 may need to be revised as Figure 2B is shown so that these characteristics and capabilities are provided as modified output Q'209'. As shown, it can be seen that functi...

Abstract

An architecture including reconfigurable bridges for routing data between functional units is provided. Routing of data between registers associated with each functional unit is performed by a register transfer unit. Both synchronous and asynchronous register transfers are supported, including generation of interrupt signals to support active digital signal processors. A preferred embodiment of the reconfigurable bridge includes a plurality of reconfigurable datapath units that provide auxiliary functions to facilitate processing and preprocessing of data items as they are transferred between registers. The preferred embodiment of the present invention also includes an instruction memory containing instructions for performing desired register transfers and auxiliary operations.

Description

technical field [0001] The present invention relates to the field of signal processing, in particular to a programmable bridge that facilitates the processing of digital signal streams between various functional units and one or more digital signal processors. Background technique [0002] Figure 1A An exemplary block diagram of an exemplary system 100 for receiving and processing source input 101 for rendering by a user application 150 is shown. For example, source input 101 may be a broadcast television signal and user application 150 may be a reproduction of a television program on a display screen. Source input 101 may be an optical signal from a DVD or CD player, and user application 150 may be a video or analog reproduction device. Source input 101 may be a satellite or cellular phone signal, and user application 150 may be a wireless phone. [0003] An analog processor 110 performs filtering and amplification on the analog source input 101, and a digital-to-analog ...
