An electronic circuit, in particular a receiver circuit contains a chain of stream processing circuits ( 10 a-c). The stream processing circuits ( 10 a-c) have control parameter inputs for receiving control parameter values. In order to facilitate design of circuits that receive data with a variable block size, a control circuit ( 14 ) is included that selects block sizes of blocks of samples in the respective streams of a plurality of the stream processing circuits ( 10 a-c), a control parameter value for each particular block. The control circuit transmits instructions that specify the selected block sizes and control parameter values to local control circuits ( 11 ). Each local control circuit is coupled to the control circuit ( 14 ) and the control input of a respective corresponding stream processing circuit ( 10 a-c) from the chain. Each particular local control circuit ( 11 ) is arranged to receive at least part of the instructions and to apply parameter values from the instructions to its corresponding stream processing circuit ( 10 a-c). The particular local control circuit ( 11 ) controls timing of control parameter updates using block sizes from the instructions by counting off block size dependent time intervals between times points of successive control parameter updates. As a result there is no need to adapt the design of the stream processing circuits ( 10 a-c) to the block sizes.
