Providing ASIC equivalents of FPGAs is facilitated and made more efficient and economical by using an ASIC architecture including a plurality of so-called hybrid logic elements (“HLEs”), each of which can provide a portion of the full functionality of an FPGA logic element (“LE”). The functionality of each FPGA LE implementing a user's logic design can be mapped to one or more HLEs without re-synthesis of the user's logic. Only as many HLEs as are necessary are used to perform the functions of each LE. The one-for-one equivalence between each LE and either (1) one HLE or (2) a group of HLEs facilitates mapping (without re-synthesis) in either direction between FPGA and ASIC designs.

The invention discloses a positive feedback XOR / XNOR gate and a hybrid logic adder. The hybrid logic adder comprises a positive feedback XOR / XNOR gate and an output circuit. The positive feedback exclusive-OR / XNOR gate comprises a first PMOS tube and a second PMOS tube which are used as transmission tubes, and a first NMOS tube and a second NMOS tube which form a pull-down network. The third PMOStube, the third NMOS tube and the fourth NMOS tube form a positive feedback loop; when the exclusive-OR logic output end of the positive feedback exclusive-OR / exclusive-OR gate is pulled down to be below the switching threshold value of an inverter composed of a third PMOS tube and a fourth NMOS tube, the exclusive-OR logic output end of the positive feedback exclusive-OR / exclusive-OR gate is switched off. The positive feedback loop starts to work, so that the exclusive-OR logic output end of the positive feedback exclusive-OR / XNOR gate enters an accelerated pull-down period and is successfully pulled down to a low level, and threshold-voltage-loss-free is realized; the invention has the advantages of no threshold voltage loss, and small time delay and power consumption time delay product.

The invention discloses a method for controlling a double-shaft parallel hybrid power urban bus. The method comprises the following steps that a power transmission system model is set up; linear fitting is carried out; the reachable area of a state of charge (SOC) is pre-determined; a prediction control model is set up; a hybrid integral linear programming problem is solved. According to division of the work modes and the dynamic characteristic of hybrid logic, the work modes of the hybrid power bus can be freely switched according to running conditions and the behavior of a driver, and therefore torque is distributed to an engine and a motor through an optimal method. The problem that due to a control method based on rules, torque distribution cannot be automatically optimized according to the running conditions is effectively solved. The defect that only the current moment can be considered in instantaneous optimization is effectively overcome through the prediction model. When the range of visibility is predicted, duration enabling the relative error of the prediction result and an ideal value to be small can be found according to experiments, and the strict requirement for the whole running conditions in global optimization is effectively eliminated.
