Time-multiplexed, asynchronous device

A method for asynchronous time multiplexing of information with synchronous interfacing;

• comprising:
• receiving a clock signal;
• responsive to a first edge of the clock signal, initiating a first request;
• loading multiple sets of inputs via an input data interface;
• acknowledging the loading;
• sequentially processing each of the multiple sets of inputs to provide respective sets of outputs;
• temporarily storing the sets of outputs;
• initiating a second request responsive to storage of the sets of outputs;
• and
• responsive to a second edge of the clock signal and the second request, unloading the sets of outputs via an output data interface;
• wherein the sequentially processing of the multiple sets of inputs is asynchronously time multiplexed;
• and
• wherein the input data interface and the output data interface appear synchronous with respect to the clock signal.

A circuit for asynchronous time multiplexing with synchronous interfacing, comprising:

• a synchronous-to-asynchronous converter to receive a clock signal to cause first parallel data to be loaded;
• a first asynchronous shift register to shift in the first parallel data and to shift out first serial data therefrom;
• a function block to process the first serial data to provide second serial data;
• a second asynchronous shift register to shift in the second serial data and to shift out second parallel data therefrom;
• and
• an asynchronous-to-synchronous converter to receive the clock signal to cause the second parallel data to be unloaded;
• wherein asynchronous pipelining of the first serial data and the second serial data from the first asynchronous shift register to the second asynchronous shift register provides for asynchronously time multiplexing multiple operations associated with multiple sets of data of the first parallel data.
