摘要： A processing unit for executing parallel cumulative absolute difference operations in a first mode, and an inner product operation in a second mode, includes an input bus group for receiving first input data, second input data, and third input data. A plurality of processor elements are coupled to the input bus group, each processor element being coupled to compute a cumulative absolute difference between the first input data and the second input data in the first mode, and to compute and accumulate one term of Booth's algorithm for multiplying the first input data by the third input data in the second mode. An output bus group is coupled to the processor elements, for receiving the terms of Booth's algorithm. An accumulator circuit is coupled to the output bus group, for shifting and adding terms of Booth's algorithm output by the processor elements.

摘要： In addition to two-stage CMOS inverters for inverting and amplifying the input signal IN, a rising edge detector 3 for detecting the rising edge of the input signal IN, and outputting a rising edge detection signal S3 having a pulse width corresponding to the ambient temperature, and a PMOS 5 for driving the output node NO to the power supply potential VDD according to the rising edge detection signal S3, and the falling edge detector 4 for detecting the falling edge of the input signal IN and outputting a falling edge detection signal S4 having a pulse width corresponding to the ambient temperature, and an NMOS 6 driving the output node NO to the ground potential GND according to the falling edge detection signal S4. When the ambient temperature rises, and the delay time of the CMOS inverters 1, 2 are thereby increased, the pulse widths of the rising edge detection signal S3, and the falling edge detection signal S4 are also increased, and because of the additional driving by means of the PMOS 5 and the NMOS 6, the delay time is reduced. Thus, the variation in the delay time in the driving circuit in an LSI, due to the ambient temperature change can be restrained.
