Abstract: A process for protecting children online from sexual predators, contemplated suicide, and premeditated school violence is disclosed: Human female nannys remotely watch computer screens of subscribed children. Using a small cadre of nannys, it is explained why watching large numbers of children is feasible. First, redundancy is introduced to minimize likelihood of a false positive and to ensure no dangerous activity be missed. Next, several forms of time compression are incorporated into the review of children's activities. Further, allocation of nannys to children is expressed mathematically as a covex optimization problem. Review-time of children's activities is thereby minimized with, provably, no better allocation.

Abstract: A digital signal processor for efficiently handling audio applications is disclosed. The single chip digital signal processor includes an on-chip instruction memory for outputting instructions representing an audio application program. Four busses, W, X, Y and Z, provide communication within the processor. An ALU performs a plurality of arithmetic and logical functions according to the instruction memory. Specialized implementations for functions have been specially developed for audio applications, for example, a single cycle average instruction, a jump on condition code instruction, a repeat instruction, a limit instruction. A Multiplier Accumulator/Barrel Shifter performs a plurality of MAC and shifting functions according to the instruction memory. The MAC/BS is coupled in parallel with the ALU and an Address Generator. The Address Generator performs a plurality of address calculation functions according to the instruction memory.
