An access controller for controlling access by a debugger to a set of program instructions stored on a computing device or for inhibiting access by a debugger to memory locations used by the set of program instructions. The access controller being responsive to a control signal indicative of a request by the debugger to access at least part of the set of program instructions to determine that the requested set of program instructions includes a subset of instructions to which access by the debugger is to be restricted. The access controller can inhibit the debugger from causing the computing device to suspend execution of the requested set of program instructions at an instruction contained in the subset of instructions when the computing device is executing the requested set of program instructions responsive to the debuggers request. The access controller can also inhibit the debugger from accessing memory locations used during the execution of the restricted subset of instructions both while executing and following suspension. The access controller may determine whether to inhibit access of the debugger to memory locations or inhibit the suspension of execution based upon an authorization key associated with the instructions. |
