Transposing in a matrix-vector processor

A non-transitory computer program product storing instructions that, when executed by at least one programmable processor within a circuit that comprises reversal circuitry, counter circuitry, and rotation circuitry, cause the at least one programmable processor to perform operations comprising:

• receiving, by the reversal circuitry of the circuit, elements of a diagonal of a matrix that are inserted in a first vector;
• positioning, by the reversal circuitry of the circuit, the received elements of the diagonal in a second vector in an order that is a reverse of the order of the elements in the first vector;
• counting, by the counter circuitry of the circuit , a predetermined number of positions;
• receiving, by the rotation circuitry of the circuit and from the counter circuitry of the circuit, one or more counter signals indicating the predetermined number of positions;
• and
• generating, by the rotation circuitry of the circuit and based on the one or more counter signals, a third vector by inserting the elements of the second vector in the third vector in an order that is a rotation of the elements of the diagonal by the predetermined number of positions that is counted by the counter circuitry of the circuit.

A circuit comprising reversal circuitry, counter circuitry, and rotation circuitry, wherein the circuit is configured to receive, by the reversal circuitry, a first vector that has elements of a diagonal of a matrix in a first order;

• generate, by the reversal circuitry, a second vector that has the elements in a second order that is a reverse of the first order;
• count, by the counter circuitry, a predetermined number of positions;
• receive, by the rotation circuitry and from the counter circuitry, one or more counter signals indicating the predetermined number of positions;
• and generate, by the rotation circuitry, a third vector that has the elements in a third order that is a rotation of the elements in the second order by the predetermined number of positions that is counted by the counter circuitry.
