    • A processing device (10) provides general-purpose input/output pins (52) for use by software routines as needed. A data input register (54) has bits corresponding to each pin (52) for storing the value of the signal on the pin. A data output register (56) has bits corresponding to each pin for driving the signal on the pin (52) to a desired value. An output enable register (58) controls output buffers (62) coupled between the output register (56) and the pins (52). A plurality of mask registers (60) may be individually set to define a set a pins associated with the mask. Each of the data registers, the data input register (56), the data output register (58) and the output enable register (60) are accessed through a plurality of addresses, where the address specifies both the data register being accessed and an associated mask register (60). Logic (50) accesses the data registers in view of the state of the associated mask register (60).

    • An equalization circuit that allows particularly for lowpass filtering by transmission lines comprises a compensating equalizer controlled according to whether the edges between bits in the data waveform are early or late. Adjusting the equalization causes edges to appear in the same place, whereas if the adjustment is incorrect certain edges will be late and certain edges will be early depending on the history of “1”s and “0”s in the data stream. This is an effect of so-called intersymbol interference. The control mechanism includes circuits for recognizing patterns of “1”s and “0”s in the recent history of the data waveform whose occurrence is used to trigger the adjustment of the equalizer.
    • 特别是允许传输线进行低通滤波的均衡电路包括根据数据波形中的位之间的边缘是早还是晚的控制的补偿均衡器。 调整均衡会使边缘出现在相同的位置,而如果调整不正确,则某些边缘将迟到,某些边缘将提前取决于数据流中“1”和“0”的历史记录。 这是所谓的码间干扰的影响。 控制机构包括用于识别出现用于触发均衡器的调整的数据波形的最近历史中的“1”和“0”的模式的电路。

    • A circuit for receiving multiple serial datastreams in parallel is disclosed. A bit clock is recovered from each data stream, there being one data bit for ach transition of the clock signal both positive and negative going. The phases of the bit clocks are compared and are adjusted by 180 degrees so that the positive going edges of all occur close to each other. The bits of each stream are assembled into words under the control of a word clock. In one embodiment a common word clock is derived form the set of bit clocks as a whole. In another embodiment each stream is provided with its own word clock which is aligned to positive edges of the respective bit clocks that are close to each other.

    • A magnitude comparator employs plural layers of repeated circuits which are scalable to any size. The magnitude comparator indicates whether two multibit inputs are equal, and if not equal indicates if a first multibit input is greater than a second multibit input. A single bit comparator circuit receives a corresponding bit of the two multibit inputs. Each single bit comparator generates an A=B output equal to the exclusive NOR of the two inputs and an A>B output equal to the first input. The magnitude comparator includes at least one two bit comparator circuit disposed in at least one layer. Each two bit comparator circuit includes an A[0]=B[0] input, an A[0]>B[0] input, an A[1]=B[1] input and an A[1]>B[1] input. Each two bit comparator circuit generates an A=B output of an AND of signals received at the A[0]=B[0] and A[1]=B[1] inputs. Each two bit comparator circuit generates an A>B output equal to the A[1]>B[1] input if the A[0]=B[0] input is "1" and equal to the A[0]>B[0] input if the A[0]=B[0] input is "0".
