摘要： There is provided an information processing device to reduce a processing load associated with inner product operations while also guaranteeing the quantization granularity of weight coefficients, the information processing device including: a multiply-accumulate operation circuit configured to execute a multiply-accumulate operation on the basis of multiple input values and multiple weight coefficients that are quantized by an exponential representation and that correspond to each of the input values. Exponents of the quantized weight coefficients are expressed by fractions taking a predetermined divisor as a denominator, and the multiply-accumulate operation circuit performs the multiply-accumulate operation using different addition multipliers on the basis of a remainder determined from the divisor.

摘要： A signal processing method comprising rearranging transmission data so that a predictable portion of the transmission data is spread more uniformly in the transmission data, the predictable portion including information that is predictable by a receiver side. The phase of a carrier signal can be modulated based on the rearranged transmission data, and the modulated signal may be transmitted. The transmitted signal is received by the receiver side. A header position of each frame of the received signal is detected based on the information predictable to the receiver side. Once detected, the frames of the received signal are integrated, and the transmission data is decoded based on the integration. A signal processing device, a transmitter, and/or a receiver may utilizes these methods to transmit, receive, and/or process signals.
