mc14514b, MC14515B http://onsemi.com 7 complex data routing two mc14512 eight ? channel data selectors are used here with the mc14514b four ? bit latch/decoder to effect a complex data routing system. a total of 16 inputs from data registers are selected and transferred via a 3 ? state data bus to a data distributor for rearrangement and entry into 16 output registers. in this way sequential data can be re ? routed or intermixed according to patterns determined by data select and distribution inputs. data is placed into the routing scheme via the eight inputs on both mc14512 data selectors. one register is assigned to each input. the signals on a0, a1, and a2 choose one of eight inputs for transfer out to the 3 ? state data bus. a fourth signal, labelled dis, disables one of the mc14512 selectors, assuring transfer of data from only one register. in addition to a choice of input registers, 1 thru 16, the rate of transfer of the sequential information can also be varied. that is, if the mc14512 were addressed at a rate that is eight times faster then the shift frequency of the input registers, the most significant bit (msb) from each register could be selected for transfer to the data bus. therefore, all of the most significant bits from all of the registers can be transferred to the data bus before the next most significant bit is presented for transfer by the input registers. information from the 3 ? state bus is redistributed by the mc14514b four ? bit latch/decoder. using the four ? bit address, d1 thru d4, the information on the inhibit line can be transferred to the addressed output line to the desired output registers, a thru p. this distribution of data bits to the output registers can be made in many complex patterns. for example, all of the most significant bits from the input registers can be routed into output register a, all of the next most significant bits into register b, etc. in this way horizontal, vertical, or other methods of data slicing can be implemented. data routing system input registers data transfer data distribution output registers 3?state data bus register a register p register 1 register 8 register 9 register 16 data select strobe inhibit dis dis q q d1 d2 d3 d4 a0 a1 a2 a0 a1 a2 mc14514b mc14512 mc14512 d0 d1 d2 d3 d4 d5 d6 d7 d0 d1 d2 d3 d4 d5 d6 d7 s15 s14 s13 s12 s11 s10 s9 s8 s7 s6 s5 s4 s3 s2 s1 s0
