Cell array circuitry

Cell array circuitry including:

• respective first, second, third and fourth cell arrays, each cell array being made up of a plurality of mutually-corresponding cells arranged in rows and columns and each of said second, third and fourth cell arrays being placed in a predetermined spatial relationship with respect to the first cell array, each cell including a circuit which defines a respective analog quantity;
• a cell set selection circuit which selects the cells of the arrays in sets, each such cell set including a first cell from the first cell array and also including a second cell from the second cell array, which second cell corresponds individually to the first cell of the cell set concerned, and also including a third cell from the third cell array, which third cell corresponds individually to the first cell of the cell set concerned, and a fourth cell from the fourth cell array, which fourth cell corresponds individually to the first cell of the cell set concerned;
• the physical arrangement of such second cells within the second cell array corresponding to a predetermined transformation of the physical arrangement of their respective corresponding first cells within the first cell array, and the physical arrangement of such third cells within the third cell array corresponding to a predetermined transformation of the physical arrangement of their respective corresponding first cells within the first cell array and the physical arrangement of such fourth cells within the fourth cell array corresponding to a predetermined transformation of the physical arrangement of their respective corresponding first cells within the first cell array;
• and
• an accumulation circuit which accumulates respective analog quantities defined by the first, second, third and fourth cells of a selected cell set.

Cell array circuitry including:

• respective first and second cell arrays, each cell array being made up of a plurality of mutually-corresponding cells arranged in rows and columns, each cell including a circuit which defines a respective analog quantity, the second cell array being placed in a predetermined spatial relationship with respect to the first cell array, wherein in each cell array the cells are assigned respective ordinal positions in a predetermined selection sequence, which assigned ordinal positions are such as to tend to equalize the respective sequence-position sums for different rows of the array concerned and/or to tend to equalize the respective sequence-position sums for different columns of the array concerned, where the sequence-position sum for a row or column is determined by summing the respective ordinal positions of the cells in the row or column concerned;
• a cell set selection circuit which selects the cells of the arrays in sets, each such cell set including a first cell from the first cell array, selected in accordance with its said assigned ordinal position in said first cell array, and an individually-corresponding second cell from the second cell array, selected in accordance with its said assigned ordinal position in said second cell array, and the physical arrangement of such second cells within the second cell array corresponding to a predetermined transformation of the physical arrangement of their respective corresponding first cells within the first cell array;
• and
• an accumulation circuit which accumulates respective analog quantities defined by the cells of the selected cell sets.

Cell array circuitry including:

• respective first and second cell arrays, each cell array being made up of a plurality of mutually-corresponding cells arranged in rows and columns, each cell including a circuit which defines a respective analog quantity, the second cell array being placed in a predetermined spatial relationship with respect to the first cell array, wherein the first and second cell arrays are spaced apart in a first direction, and a centreline of the second cell array that extends centrally through the array in the first direction is aligned with a centreline of the first cell array that extends centrally through the array in the first direction, and each cell array has a first half on one side of its said centreline and a second half on the other side of its said centreline;
• a cell set selection circuit which selects the cells of the arrays in sets, each such cell set including a first cell from the first cell array and an individually-corresponding second cell from the second cell array, the physical arrangement of such second cells within the second cell array corresponding to a predetermined transformation of the physical arrangement of their respective corresponding first cells within the first cell array, which predetermined transformation involves copying the first half of the first cell array into the second half of the second cell array, and copying the second half of the first cell array into the first half of the second cell array;
• and
• an accumulation circuit which accumulates respective analog quantities defined by the first and second cells of a selected cell set.
