Abstract: A method includes receiving, by a memory management unit (MMU) comprising a translation lookaside buffer (TLB) and a configuration register, a request from a processor core to directly modify an entry in the TLB. The method also includes, responsive to the configuration register having a first value, operating the MMU in a software-managed mode by modifying the entry in the TLB according to the request. The method further includes, responsive to the configuration register having a second value, operating the MMU in a hardware-managed mode by denying the request.

Abstract: A finless projectile provides improved ease of use, aerodynamics, muzzle velocity, drag, target, and excursion accuracy, structural integrity, terminal effectiveness and safety, at lower cost. The finless projectile includes a slug, a forward projectile body, an aft projectile body, an obturator, and a pad. The finless projectile is a full bore projectile that defines a hollow core, but does not include a sabot nor does it carry explosives. The finless projectile functions by kinetic energy transfer from the projectile to the target by deforming the target. The center of gravity of the finless projectile is forward of the center of pressure to provide static stability to the finless projectile.
