Abstract: A first systolic array receives an input set of time division multiplexed matrices from a plurality of channel matrices. In a first mode, the first systolic array performs triangularization on the input matrices, producing a first set of matrices, and in a second mode performs back-substitution on the first set, producing a second set of matrices. In a first mode, a second systolic array performs left multiplication on the second set of matrices with the input set of matrices, producing a third set of matrices. In a second mode, the second systolic array performs cross diagonal transposition on the third set of matrices, producing a fourth set of matrices, and performs right multiplication on the second set of matrices with the fourth set of matrices. The first systolic array switches from the first mode to the second mode after the triangularization, and the second systolic array switches from the first mode to the second mode after the left multiplication.

Abstract translation: 第一收缩阵列从多个信道矩阵接收时分多路复用矩阵的输入集合。 在第一模式中，第一收缩阵列在输入矩阵上执行三角化，产生第一组矩阵，并且在第二模式中对第一集合执行反替代，产生第二组矩阵。 在第一模式中，第二收缩阵列利用输入的矩阵集在第二组矩阵上执行左乘法，产生第三组矩阵。 在第二模式中，第二收缩阵列在第三组矩阵上执行交叉对角线转置，产生第四组矩阵，并且在具有第四组矩阵的第二组矩阵上执行右乘法。 第一收缩阵列在三角化后从第一模式切换到第二模式，并且第二收缩阵列在左乘法之后从第一模式切换到第二模式。
