| 摘 要： | 针对Multibus(多总线)非总线矢量中断只能受理8个矢量中断请求的限制,在我们研制的面向Multibus的CAMAC机箱控制器中,采用三片可编程中断处理片8259A,用来处理24个LAM请求。提高了Multibus非总线矢量中断受理LAM请求的响应速度,增加了CAMAC系统选择LAM处理优先级方式的灵活性。

| Abstract: | In this paper, an implementation scheme for speedup of LAM processing is presented.
Because, in the multibus, non-bus vectored interrupt (NBVI) is limited to 8 vectored interrupts, a multibus crate controller has been developed, and 3 programmable interrupt controllers 8259A have been adopted.
This implementation acheme raises the speed of responding to multibus NBVI processing LAM requests and increases the CAMAC system flexibility to select the priority pattern in LAM processing. |
