Rate domain numerical processing circuit and method

A numerical processing circuit, comprising:

• an input configured to receive an input serial data stream on a single input wire, the input serial data stream representing a multi-valued number as a rate of pulse events including pulses, null pulses or a combination thereof;
• a numeric input configured to receive an operand;
• logic circuitry configured to scale the rate by the operand in an output serial data stream to perform a multi-valued arithmetic operation selected from multiplication, division, addition and subtraction or a combination thereof;
• and
• an output configured to output the output serial data stream on a single output wire.

A numerical processing circuit for processing serial data in a rate domain, comprising:

• an input configured to receive an input serial data stream on a single input wire, the input serial data stream representing a multi-valued number as a rate of pulse events including pulses, null pulses or a combination thereof;
• a numeric input configured to receive an operand;
• logic circuitry configured to count pulse events and compare the count to the operand to vary the rate of pulse events in an output serial data stream to perform a multi-valued arithmetic operation selected from multiplication, division, addition and subtraction or a combination thereof;
• and
• an output configured to output the output serial data stream on a single output wire.

• an input configured to receive an input serial data stream on a single input wire, the input serial data stream representing a multi-valued number as a rate of pulse events including pulses, null pulses or a combination thereof;
• a numeric input configured to receive an operand;
• logic circuitry configured to use the operand to vary the rate of pulse events in an output serial data stream to perform a multi-valued arithmetic operation selected from multiplication, division, addition and subtraction or a combination thereof;
• and
• an output configured to output the output serial data stream on a single output wire.
