Claim 11:
12. A ferromagnetic multiplier comprising:
a continuous lower layer of ferromagnetic material;
a thin conductive layer positioned adjacent to the continuous lower layer of ferromagnetic material;
a plurality of ferromagnetic regions on a layer adjacent to the thin conductive layer, the plurality of ferromagnetic regions arranged in a sparse rectangular array having a first column, a second column, a third column, a fourth column, and a fifth column, the sparse rectangular array also having a first row, a second row, a third row, a fourth row, a fifth row, a sixth row, a seventh row, an eighth row, a ninth row, and a tenth row;
the plurality of ferromagnetic regions further comprising:
input ferromagnetic regions comprising: a multiplier first input having a low order an a0 bit input formed as a plurality of ferromagnetic regions in the second column first row and fourth column fifth row of the sparse rectangular array;
the multiplier first input having a high order a1 bit input formed as a plurality of ferromagnetic regions in the sparse rectangular array further comprising ferromagnetic regions in the second column fifth row and second column eighth row;
a multiplier second input having a low order b0 bit input formed as a plurality of individual ferromagnetic regions in the first column second row, first column fourth row, and fifth column sixth row;
the multiplier second input having a high order b1 bit input formed as a plurality of individual ferromagnetic regions in the first column sixth row, first column ninth row, and fifth column fourth row;

constant value ferromagnetic regions comprising:
a one value ferromagnetic region located at the third column third row and a one value ferromagnetic region located at the fourth column ninth row;
a plurality of zero value ferromagnetic regions located at the second column, third and seventh rows, third column fifth row, and fourth column third and seventh row;

a plurality of output ferromagnetic regions comprising:
an m0 output bit formed by a magnetization direction of a ferromagnetic region in the second column second row;
an m1 output bit formed by a magnetization direction of a ferromagnetic region in the third column fourth row;
an m2 output bit formed by a magnetization direction of a ferromagnetic region in the third column ninth row;
an m3 output bit formed by a magnetization direction of a ferromagnetic region in at least one of: the third column sixth, seventh, or eighth rows;

and where the one value comprises a first magnetization direction in an orientation parallel to a long axis of the sparse rectangular array and the zero value comprises a magnetization direction in an opposite direction of the first magnetization direction.
