Abstract
The present invention provides a method and apparatus for updating serial devices. The apparatus includes a plurality of serial registers. The apparatus further includes a device adapted to provide a signal and a plurality of parallel registers, wherein each of the parallel registers is adapted to access at least one of the plurality of serial registers at substantially the same time in response to detecting the signal.
Claims21
An apparatus, comprising:
- a plurality of serial shift registers;
- a controller configured to provide data serially to the plurality of serial shift registers;
- wherein the plurality of serial shift registers are arranged in series in a ring such that the data provided by the controller is shifted sequentially from one serial shift register to another until at least a portion of the serial shift registers have been loaded with the data;
- a device adapted to provide a signal;
- and
- a plurality of parallel registers, wherein each of the parallel registers is adapted to access the data within a respective one of the plurality of shift serial registers at substantially the same time in response to detecting the signal.
3 more elements
A method, comprising:
- arranging a plurality of serial shift registers in series, in a ring;
- providing data serially to plurality of serial shift registers;
- shifting the data sequentially from one serial shift register to another until at least a portion of the serial shift registers have been loaded with the data;
- detecting a signal;
- and
- accessing the data in the at least a portion of the plurality of serial shift registers in parallel at substantially the same time in response to detecting the signal.
3 more elements
A system, comprising:
- a plurality of serial shift registers;
- a first controller adapted to provide data serially to the plurality of serial shift registers via a bus;
- wherein the plurality of serial shift registers are arranged in series in a ring such that the data provided by the controller is shifted sequentially from one serial shift register to another until at least a portion of the serial shift registers have been loaded with the data;
- and
- a plurality of parallel registers, each coupled to a respective one of the serial shift registers, wherein the parallel registers are adapted to access the data in the respective ones of serial shift registers at substantially the same time in response to receiving a signal.
