A digitally controlled impedance driver circuit including a number of fingers, some of which having FETs and series resistors sized in binary or other differential ratios, and some of the higher power FETs being sized in equal ratio and perhaps sharing a series resistor. A DCI controller circuit periodically determines a configuration of the DCI driver circuit that would result in the DCI driver circuit approximating a target impedance. Each time the DCI controller circuit does this, a comparator determines if the impedance of the DCI driver circuit should be increased or decreased. A noise attenuation circuit turns off (or on) only one of the high power fingers if the controller circuit determines that more (or less) impedance is needed even if turning off (or on) only one of the fingers would not result in the configuration of the DCI driver circuit determined by the controller circuit.

The present invention discloses a pointer generator which generates pointer values for a stack (LIFO memory). The pointer generator includes a selection input terminal and a bi-direction linear feedback shift register. The selection input terminal transmits a selection signal to the bi-direction linear feedback shift register in response to a command to read/write the stack. The fundamental structure of the bi-direction linear feedback shift register is a linear feedback shift register. After receiving the selection signal from the selection input terminal, the bi-direction linear feedback shift register performs calculation of a specific primitive characteristic polynomial, and then creates a number sequence. When the selection signal changes, the bi-direction linear feedback shift register creates another number sequence by performing calculation of another specific primitive characteristic polynomial. The two number sequences are exactly opposite to each other in order. Therefore, one sequence can be used as up-counting stack pointer values for the “write” command, and the other sequence can be used as down-counting stack pointer values for “read” command.
