  • Data interface circuit
    Patent number: 8451147
    Abstract: In an illustrative embodiment, a data interface circuit is provided. The data interface circuit comprises data sources, input blocks, a space switch, output blocks and a multi-core processor. The data interface circuit allows data provided in different voltage ranges and sampling frequencies to be transmitted to the appropriate core in the multi-core processor via the switch. Data conversion elements in the input blocks convert data from the data sources and having varying voltage ranges and sampling frequencies into data having a voltage range and sampling frequency suitable for the space switch. Analogously, data conversion elements in the output blocks convert data from the space switch into data having a voltage range and sampling frequency suitable for the corresponding core in the multi-core processor. In one embodiment, level shifters and FIFO buffers are used in the input blocks and output blocks.
