    • A method of driving a dual axis shearing type crushing machine mounted on a self-traveling vehicle body for crushing crushable building scraps at a building wrecking site. The crushing machine includes a pair of rotary shafts provided with a plurality of cutters within a housing on the vehicle body. The rotary shafts are supported sidelong so as to be concurrently rotatable, and the crushing machine also includes a scraper attached to an inner surface of the housing on the vehicle body so as to oppose the cutters and the rotary shafts. The method includes the steps of: (a) rotating the pair of rotary shafts in a forward direction for a first predetermined time duration so that the cutters crush the crushable building scraps into crushed pieces; (b) thereafter rotating the pair of rotary shafts in a reverse direction for a second predetermined time duration so that the crushed pieces are drawn into and trapped in a spacing provided between the scraper and the cutters and the rotary shafts at an outlet side of the crushing machine within the housing; and (c) continuously repeating the steps (a) and (b) in succession so as to consecutively crush the crushable building scraps into the crushed pieces and force the crushed pieces to be fed from the outlet side of the crushing machine out of the housing so as to enable the crushed pieces to be discharged onto a conveyor provided on the vehicle body without clogging of the crushed pieces in the spacing.

    • An address generating circuit of simple configuration for repeating a selected block of instructions is provided. An instruction address maintained by program counter 72 is compared to register 76 that holds the address of the end of the selected block of instructions. When the end address is detected, the program counter is loaded with a starting address of the block of instructions, which is stored in register 80. Block repeat count register 86 maintains a repeat count. Zero detection circuit 70 delays decrements of register 86 by a number of clock cycles that is equivalent to a pipeline depth for instruction prefetching of a processor connected to program counter 72. The zero detection circuit 70 outputs a loop-end control signal which controls a selector to selectively provide an incremented address or the start address to the program counter. By delaying decrements of register 86, the state of the repeat count is correctly maintained when the processor pipeline is flushed during an interrupt. The zero detection circuit also deactivates the loop-end control signal for the number of clock cycles equivalent to the depth of the prefetch pipeline during the final repeat loop iteration(s) so that a loop with a block size less than or equal to the depth of the prefetch pipeline can be repeated the correct number of times.
    • 提供了一种用于重复所选择的指令块的简单配置的地址产生电路。 由程序计数器72维护的指令地址与保存所选指令块的结束地址的寄存器76进行比较。 当检测到结束地址时,程序计数器加载存储在寄存器80中的指令块的起始地址。块重复计数寄存器86保持重复计数。 零检测电路70将寄存器86的减少延迟多个时钟周期,这些时钟周期等同于用于连接到程序计数器72的处理器的指令预取的流水线深度。零检测电路70输出控制选择器的环路端控制信号 选择性地向程序计数器提供增加的地址或起始地址。 通过延迟寄存器86的递减,当处理器管线在中断期间被刷新时,重复计数的状态被正确地保持。 零检测电路还在最终重复循环迭代期间使等效于预取流水线的深度的时钟周期数的环路端控制信号去激活,使得具有小于或等于深度的块大小的环路 的预取管道可以重复正确的次数。
