Abstract
Signal processing apparatus comprises a control read only memory storing: PA1 (i) two or more sets of signal processing parameter data to control signal processing operations of the apparatus; and PA1 (ii) configuration data specifying one of the sets of signal processing parameter data stored in the control read only memory; PA1 a control read/write memory capable of storing: PA1 (i) at least one set of signal processing parameter data; and PA1 (ii) configuration data capable of specifying a set of signal processing parameter data stored in the control read only memory or a set of signal processing parameter data stored in the control read/write memory; and control logic, responsive to an input selection signal specifying whether the configuration data in the control read only memory or the configuration data in the read/write memory should be selected for use, for controlling the signal processing apparatus to perform signal processing operations in accordance with the signal processing parameter data specified by the selected configuration data.
