Title: Quantization circuit
Inventor: KATAYAMA KUNIHIRO
IPC: H04N19/42
Filed: 1993-03-23
Abstract: PURPOSE:To obtain the quantization circuit of a reduced circuit scale, which executes at high speed. CONSTITUTION:A rounding constant X is stored in a rounding constant register 101 for inputting a positive number when a DCT coefficient R is positive and a rounding constant X is stored in a rounding constant register 102 for inputting a negative number when a DCT coefficient R is negative. A selecting circuit 103 selects a rounding constant for a positive or negative number by the code bit of a DCT coefficient R and inputs it to an adder 105. On the other hand, a multiplier 104 obtains the product of the DCT coefficient R and the inverse number A of a quantization threshold value. The adder 105 obtains (AR+X), a shifter 106 shifts it to right by S bits and a range limitting circuit 107 limits the range of a quantization coefficient to a specified value. Thereby, the DCT coefficient R is quantized by the quantization threshold value Q to obtain the result L rounded into an integer.

Title: Semiconductor device
Inventor: KOROGI YASUHIRO
IPC: G11C16/06
Filed: 1990-03-14
Abstract: PURPOSE:To operate stably even a semiconductor device incorporating a latch circuit sealed to a window package from which a light irradiates by detecting a change in a power voltage and setting a level of a region effected by irradiation with light to a power level. CONSTITUTION:A node N1 reaches a negative level before application of power and the level gradually rises by the action of a capacitor C1 attended with the increase in the power supply after application of power. A power voltage detection circuit VS detects a change in the power voltage and gives the voltage to a P-channel transistor(TR) Q3. The TR Q3 is energized when the voltage reaches the operating voltage so as to boost the level of the node N1 to a threshold level of the CMOS inverter Q2 or over. In this state, when an output of the circuit VS reaches the power voltage level and a TR Q3 is nonenergized, the level of the node N1 rises as the power voltage rises by application of feedback of the TRs Q1, Q2 and a stable L level is latched after the power voltage is constant.
