REGISTER READ MECHANISM

摘要

Integrated circuits have expanded a set of custom registers and a read mechanism for control registers. One embodiment includes a circuit having a first set of registers (19); a second set of registers to be written via one or more write operations addressed to one or more registers of the first set; and a read controller coupled with the first and second sets of registers, the read controller to selectively output a portion of data stored in the first and second sets of registers based on data stored in one or more registers of the second set. In one embodiment, the circuit further includes a logic block (17); and a multiplexer to select from an output of the logic block and an output of the read controller as an output of the circuit based on the data stored in the one or more registers of the second set.
