Abstract: An embodiment of the invention discloses phase shifting a second clock signal by a phase increment with respect to a first clock signal, where the first clock signal and the second clock signal have the same periods. The first clock signal is sampled with the second clock signal, and the output of the sample indicates whether the sample of the first clock signal is at a logic one state or a logic zero state. A count of logic one samples is incremented if the sample of the first clock signal is at a logic one state. The process of phase shifting the second clock signal and sampling the first clock signal is repetitively performed to a maximum number of samples.

Abstract: A multiprocessing apparatus includes a memory and a plurality (M) of processors coupled to share the memory. Access to the memory is time-division multiplexed among the plurality of processors. In one embodiment, a selected processor retrieves M words of instruction forming K instructions during a given clock cycle. The selected processor executes M?K NOP instructions if K<M.
