Title: Detection system for operand overlap
Inventor: SHINOHARA KOICHI
IPC: G06F9/30
Filed: 1985-03-22
Abstract: PURPOSE:To detect an operand overlap by providing an address arithmetic unit with a two-input subtracting function and calculating the difference between the 1st and the 2nd operand addresses, and using a 0 detector for the high-order three bytes and a large/small comparator for the least significant byte. CONSTITUTION:When an SS type variable-length instruction is executed, the address computing element AA4 performs subtraction between the 1st and the 2nd operand addresses. The high-order three bytes of the result are inputted to the 0 decision device 23 and the least significant byte is inputted to the comparator. When the output of the 0 decision device 23 is 1, the high-order three bytes are all 0 and the 1st and the 2nd operand addresses are at a distance of <=256 bytes, so that three is the possibility of overlapping. When the output of the 0 decision device 23 is 0, both operand addresses are at a sufficiently long distance, so they never overlap each other. Further, the comparator 24 decides whether the difference between the 1st and the 2nd operand addresses is smaller than the length of the 2nd operand or not, and when the output of the 0 decision device 23 is 1 and the output of the comparator 24 is also 1, decision device 10 decides that the operands overlap each other.

Filed: 1986-03-14
Abstract: PURPOSE:To prevent radio interference due to the approach of plurality of reading devices, by using an oscillator whose an oscillation frequency irregularly changes timewise. CONSTITUTION:An oscillator 10 uses a voltage control oscillator VCO and an oscillation control circuit FC is provided thereto to irregularly change oscillation frequency fx timewise. The electromagnetic wave from the oscillator 10 is emitted to a response device 2 from an antenna 14 and received by an antenna 20 to perform modulation corresponding to a discrimination code 23 by a modulator 21 and again emitted toward a reading device 1. In the reading device 1, the electromagnetic wave is received by the antenna 14 and the reflected wave therefrom is subjected to the frequency mixing with the signal from the oscillator 10 by a mixer 11. Two signals subjected to frequency mixing are different in frequency by the frequency transfer quantity of the modulator 21 even if the frequency fx of the oscillator 10 changes to any degree and, therefore, only the beat frequency of the modulated part is outputted to the output of the mixer 11 and a discrimination code is obtained by a receiver 12. Because the timewise change of the frequency fx is different even if the electromagnetic wave is received by other reading device, no radio interference is generated.
