Embodiment Construction

[0020] figure 1 A data processing circuit is shown comprising a timing circuit 16 and a chain of processing elements 10 a , 10 , 10 b each comprising a storage element 12 and a logic circuit 14 . Each storage element has an input (terminal) and an output (terminal). The input is coupled to the output of the processing element of the logic circuit 14 . The output is coupled to the input of logic circuit 14 in the next processing element in the chain. Although a single line is used to represent input and output, it should be appreciated that each storage element 12 can be used to receive and output its own multiple bits in parallel. Timing circuit 16 has control inputs whose outputs are coupled to respective storage elements.

[0021] In operation, logic circuit 14 forms an output signal as a function of an input signal applied to its input. Any kind of logic operations can be implemented using, for example, NAND gates, NOR gates, inverters, etc. (not shown). According to t...

Abstract

A chain of processing element (l0a, 10, 10b) with a logic circuit (14) and a storage element (12) is provided. The storage elements (12) of all except a final processing element (10b) in the chain have one or more outputs coupled to the logic circuit (14) of a next processing element (10a, 10, l 0b) in the chain. A timing circuit (16) controls respective loading time points at which the storage elements (12) load data from the logic circuits (14) in respective ones of the processing elements (10a, 10, 10b). The data is loaded progressively later in processing elements (10a, 10, 10b) that successively precede one another in the chain. The time interval between successive loading time points of the final processing element (l0b) includes loading time points of loading all processing elements(l0a, 10) other than the final processing element (10).

Description

technical field [0001] The invention relates to an electronic circuit with a chain of processing elements and a data processing method. Background technique [0002] Pipelining is a conventional technique for increasing the throughput of electronic circuits. In a pipelined circuit, a logic circuit is divided into sections, and successive sections are coupled through memory elements, and clock signals are generated by these sections. The results are loaded into storage elements at the end of these segments at the end of the clock cycle. During the next clock cycle, the results of each segment are provided to the next segment. [0003] Such pipelined circuits exhibit power consumption spikes around clock edges in order to load data into storage elements, and then generate new results. Current peaks can cause interference problems and place high demands on the power supply. One way to avoid interference problems and reduce power consumption is to use asynchronous circuits, w...
