Abstract:
1. Circuitry for accessing configuration data stored on a logic device and sending the configuration data to an output, comprising: a memory in which the configuration data is stored, wherein the memory comprises frames of memory cells; an address register capable of storing a number of bits at least equal to a number of the frames, wherein each bit stored in the address register is associated with a different frame of the frames of memory cells; a data register coupled to the memory; and control logic coupled to the memory, the address register, and the data register to access a particular frame of memory cells, wherein the control logic asserts a bit in the address register associated with the particular frame of memory cells, causes data from the particular frame of memory cells to be loaded into the data register, and causes a subset of data from the particular frame of memory cells to be loaded from the data register to the output.
