Fast logic sharing is created using a feedback path from the output logic macrocell of one functional block to the product term inputs of another function block without going through an advanced interconnect matrix (AIM). The fast feedback path may be provided from the macrocell after the product terms XOR gate without registering, and / or after the register in the macrocell. The fast logic sharing avoids the slow AIM for feedback logic, and allows additional resources to be borrowed from other function blocks with a limited delay penalty. In particular, delay penalties resulting from dividing wide operations requiring multiple product terms between the product terms of multiple functional blocks are significantly reduced.

The invention belongs to the technical field of wireless communication, and relates to a method for identifying interfered mobile terminals and methods for avoiding interference. In each system frame, a home / micro-cellular base station senses an uplink frequency spectrum to obtain an uplink physical resource block usage pattern; the home / micro-cellular base station transmits a signaling to a service macro base station via an X2 interface or an air interface, wherein the signaling comprises the uplink physical resource block usage pattern and a detected system wireless frame number; and the service macro base station searches for a history physical resource allocation database, and identifies macro cell mobile terminals using uplink physical resource blocks when the system wireless frame number is n, namely the interfered macro cell mobile terminals by comparison.

A macro-cell is incorporated into an integrated circuit (IC) design to describe a fixed arrangement of cells to be included in the IC. The IC includes a clock tree for delivering a clock signal from its root to all clocked devices (sinks) within the IC external to the macro-cell, and to a root of a clock tree subtree included within the macro-cell for delivering the clock signal from its root to sinks residing within the macro-cell. A model of the subtree depicts the maximum and minimum delays of the clock signal's rising and falling edges between the subtree root and the sinks within the macro-cell as functions of the clock signal's rising and falling edge transition times as they arrives at the subtree root and also as functions of the relative amount of delay the rising and falling edges experience as they pass from the clock tree root to the subtree root. A clock tree synthesis tool uses the subtree model to determine the maximum and minimum rising and falling edge path delays though the subtree when estimating the maximum and minimum amounts by which the clock tree delays the clock signal's rising and falling edges as they pass from the clock tree root to any sink of the IC.

A programmable array logic circuit macrocell using ferromagnetic memory cells. More particularly, the present invention uses a non-volatile ferromagnetic memory cell to temporarily store binary data. It is an advantage of the invention to have the ferromagnetic memory cells or bits to store data even when there is no power provided to the circuitry, thus saving power during operation of the programmable logic circuitry, and ensuring that there is no loss of the data should there be a temporary power shutdown. Additionally, the ferromagnetic cells provide for indefinite number of switching actions on the data without degradation to the capacity to store data therein, thus eliminating "write fatigue". The invention provides an integrated circuit, comprising a programmable OR array (24), a programmable AND array (28), coupled to the programmable OR array, and a macrocell output circuit (22). The macrocell uniquely has a ferromagnetic bit (11) and sensor (12) coupled to store remnant output signal, and an output buffer (34), coupled to output the remnant output signal upon receiving an output enable signal. The macrocell may further include a DQ register that contains the ferromagnetic bit. The DQ register may also include a drive coil, which at least partially surrounds the ferromagnetic bit. Drive coils may have a bi-directional current that sets the polarity of the ferromagnetic bit. The bi-directional current may be switched by two sets of transistor pairs (Q10 and Q11). The two sets of transistor pairs may, in turn, be gated by first and second transistor respectively. The first and second transistors may be responsive to a DATA signal that is received when a CLOCK signal is received.

The invention discloses an information transferring method and system. According to the information transferring method, a macro base station judges whether a user terminal is located in the marginal area of a macro cell and a micro cell or not and sends the parameter of a corresponding link to the user terminal according to a judgment result. The user terminal adjusts the uplink and the downlink of the user terminal according to the parameter of the link. If the macro base station determines that the user terminal is located in the marginal area of the macro cell and the micro cell, the user terminal receives first downlink information from the macro base station through the downlink and sends first uplink information to a micro base station of the micro cell through the uplink. Due to the fact that the uplink and the downlink of the user terminal can conduct communication with different cells, the quality of the uplink and the downlink of the user terminal can be guaranteed simultaneously, and interference in the user terminal is effectively reduced.
