Abstract: Each of D flip-flops (FFs) 13a to 13f constituting a scan path circuit has a normal operation input circuit to be selected in a normal operation and a test operation input circuit to be selected in a test operation, and a control signal having an intermediate voltage between a supply voltage and a ground voltage is sent from a voltage generating circuit 17 to the test operation input circuit of each FF in the test operation. In this case, the amount of an output change in data in each FF is smoother than that in the case in which the supply voltage is applied. Consequently, the delay time of the data is increased. The intermediate voltage to be applied to each FF in the test operation is determined based on a feedback signal sent from a test circuit 15 for checking whether scanned-out data have an error or not.

Abstract: A processor which executes positive conversion processing, which converts coded data into uncoded data, and saturation calculation processing, which rounds a value to an appropriate number of bits, at high speed. When a positive conversion saturation calculation instruction “MCSST D1” is decoded, the sum-product result register 6 outputs its held value to the path P1. The comparator 22 compares the magnitude of the held value of the sum-product result register 6 with the coded 32-bit integer “0x0000_00FF”. The polarity judging unit 23 judges whether the eighth bit of the value held by the sum-product result register 6 is “ON”. The multiplexer 24 outputs one of the maximum value “0x0000_00FF” generated by the constant generator 21, the zero value “0x0000_0000” generated by the zero generator 25, and the held value of the sum-product result register 6 to the data bus 18.
