Abstract
Systems and methods are provided for managing access to registers. In one embodiment, a system may include a processor and a plurality of registers. The processor and the plurality of registers may be integrated into a single device, or may be in separate devices. The plurality of registers may include a first set of registers that are directly accessible by the processor, and a second set of registers that are not directly accessible by the processor. The second set of registers may, however, be accessed indirectly by the processor via the first set of registers. In one embodiment, the first set of registers may include a register for selecting a register bank from the second set of registers, and a register for selecting a particular address within the register bank, to allow indirect access by the processor to the registers of the second set.
