Abstract
A shift register ring stores bits. A data operation may be performed in the shift register ring if bits in the shift register ring are in a home position
Claims15
A memory circuit comprising:
- a shift register ring including single-bit shift registers, wherein a clock is connected to the shift registers to shift bits within the shift register ring;
- a shift register position indication circuit to indicate positions of the bits in the shift register ring;
- and
- a data operation control circuit including
- an equality circuit to determine whether a position of a word in the shift register ring is at a home position based on information from the shift register position indication circuit and bits from an address received from a processor to perform a data operation of the processor in the shift register ring, and
- a control logic circuit to enable the data operation in the shift register ring if the word is determined to be in the home position, wherein the data operation includes reading bits from the shift register ring at one time or writing data to the shift register ring at one time.
3 more elements
A circuit comprising:
- a control logic circuit connected to a fast clock and a slow clock, wherein the fast clock and the slow clock are connected to single-bit shift registers in a shift register ring to shift bits stored in the shift register ring, and
- the control logic circuit is to
- enable the fast clock to shift the bits in the shift register ring to a home position in response to receiving a signal of a data operation to be performed for a processor in the shift register ring,
- disable the fast and slow clock in response to the bits being in the home position, wherein the data operation is performed in response to the bits being in the home position, and
- enable the slow clock to shift the bits stored in the shift register ring after the data operation is completed.
2 more elements
A method comprising:
- determining whether a position of a word in a shift register ring is at a home position based on information from a shift register position indication circuit and bits from an address received from a processor to perform a data operation in the shift register ring;
- and
- if the word is in the home position, performing the data operation in the shift register ring, wherein the data operation includes reading bits from the shift register ring at one time or writing data to the shift register ring at one time.
