Methods and apparatus for sequencing multiply-accumulate operations

A sequencer circuit, comprising:

• a wire for conveying a clock signal that provides a plurality of trigger events;
• a counter to increment by a predetermined number that is greater than one at a first trigger event of the plurality of trigger events to produce a counter output;
• a storage circuit to receive a write data signal, a read address signal, and the counter output, wherein, at a second trigger event of the plurality of trigger events, the storage circuit stores the write data signal at a first address that is based on the counter output and outputs a read data signal from a second address that is based on the read address signal;
• and
• an output coupled to an arithmetic circuit, wherein the output is configured to receive the read data signal from the storage circuit and send the read data signal to the arithmetic circuit.

A method for operating an integrated circuit that includes a multiply-accumulate circuit and a sequencer circuit, comprising:

• receiving a first read address signal at a first storage circuit in the sequencer circuit;
• retrieving a control signal from a first location in the first storage circuit that is based on the first read address signal;
• computing a second read address signal based on the control signal using an adder circuit in the sequencer circuit;
• retrieving a data signal from a second location in a second storage circuit in the sequencer circuit that is based on the second read address signal;
• and
• with the multiply-accumulate circuit, computing an output signal by multiplying the data signal with a coefficient signal.
