Abstract: An apparatus and a method for configuring or updating a programmable logic device are provided. The apparatus includes a control module and a storage module connected to the control module. The control module includes: a JTAG interface for connecting the control module to a JTAG host, and a configuration interface compatible with a to-be-configured programmable logic device. The control module is configured to: after receiving a first control instruction including configuration information via the JTAG interface, store the configuration information into the storage module; and after receiving a configuration instruction, read the configuration information to configure the to-be-configured programmable logic device. A configuration clock used in a process that the control module configures the to-be-configured programmable logic device is generated from the to-be-configured programmable logic device, the control module or an external clock source.
