  We consider Ward's generalized self-duality equations for U(2r) Yang-Mills
theory on R^{4k} and their Moyal deformation under self-dual noncommutativity.
Employing an extended ADHM construction we find two kinds of explicit
solutions, which generalize the 't Hooft and BPST instantons from R^4 to
noncommutative R^{4k}. The BPST-type configurations appear to be new even in
the commutative case.
