Title:
PROGRAMMABLE LOGIC DEVICE-BASED DATA PROCESSING APPARATUS AND DRIVING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/238527
Kind Code:
A1
Abstract:
A programmable logic device-based data processing apparatus. The data processing apparatus (100) comprises: at least one functional circuit (1051, ..., 105f) configured to process input data; and at least one current smoothing circuit (1101, ..., 110h), each of which being in one-to-one correspondence with one of the at least one functional circuit (1051, ..., 105f) and being configured to smooth a current change of the programmable logic device due to on-off switching of the corresponding functional circuit. The current smoothing circuit (1101, ..., 110h) comprises: a control circuit (1151, ..., 115h) configured to generate a driving signal on the basis of a switching mode of the functional circuit corresponding to the current smoothing circuit; and a redundant circuit (1201, ..., 120h) configured to operate according to the driving signal to smooth the current change. The control circuit (1151, ..., 115h) comprises: a decoding control word generation circuit (1251, ..., 125h) configured to generate a control word on the basis of the switching mode of the functional circuit corresponding to the current smoothing circuit; and a decoding circuit (1301, ..., 130h) configured to generate the driving signal on the basis of the control word.
