Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To increase the data communication speed of an associative memory by providing a flag resistor which discriminates whether the data stored in a memory area are valid or invalid and a counter which counts the number of memory areas storing valid or invalid data of a plurality of memory areas. SOLUTION: When a collective erasure control signal PRG-HP is activated and an entry group hit by the last retrieval is collectively erased, a flag copy control signal FEED is activated and the then value of an empty flag register 33 in an associative memory is copied in a copy flag register 36. When a flag erasure control signal SHIFT is activated thereafter, the value of the register 36 is reset. When all values of the register 36 are reset finally, the output value of an up-down counter indicates the number of vacant areas in the associative memory. Therefore, the capacity management of the associative memory can be performed in a short time without confirming the vacant states of the memory areas one by one.

Abstract: PURPOSE:To attain transmission in bit-free by using a pulse transformer to isolate a transmission line and a transmitter, modulating a transmission data at a sender side with an optimum pulse and sending the result and demodulating the modulated signal at a receiver side. CONSTITUTION:A transmission line 13 is isolated from a sender side and a receiver side transmitter respectively by using pulse transformers T1, T2. Then a modulation circuit 11 modulates a transmission data A by a modulation pulse P and outputs a resulting signal Vout and the signal Vout is subject to current amplification by a transistor(TR) 12 and inputted to the pulse transformer T1. The signal Vout sent through the transmission line 13 is rectified by a diode D1 via the pulse transformer T2 and becomes a rectified wave signal Vin by an integration circuit 14. Moreover, a hysteresis comparator 15 converts the signal Vin into a reception data V0 and the signal Vout is demodulated into a reception data signal V0. Thus, the transmission is attained in bit-free regardless of the transformer system independently of the modulation form of a serial data especially.
