Abstract: There provided a sound data delay unit for delaying sound data of a plurality of channels in a single memory area, the sound data delay unit wherein, when delay amount assigned to each channel is input into an address information generator, the address information generator generates address information for assigning storage area of the sound data for each channel in a memory, and a selector inputs the address information into the memory with respect to each channel and assigns the storage area for each channel.
Abstract: A programmable logic device with ferroelectric configuration memories storing multiple configuration data sets. The device has programmable logic blocks, interconnections, and I/O blocks to provide desired logic functions. Those building blocks can be dynamically reconfigured by changing the selection of configuration data stored in the device's integral configuration memories. The configuration memories are divided into groups, so that they can be loaded concurrently with multiple configuration data streams. To protect the content of configuration memories from unauthorized access, the device employs an authentication mechanism that uses security IDs stored in the configuration memories. The device has a memory controller to provide an appropriate power supply sequence for ferroelectric memory cells to ensure the reliable data retention when the device is powered up or shut down.
