If it did this, then the destination register would have to be twice as large as the source register.
如果的确如此，那么目的寄存器将会有源寄存器的两倍之长。With such a limited set of registers, the registers were all assigned specific purposes.
使用这样的一组受限寄存器，这些寄存器都被分配用作特定目的。SEU is the result of that electriferous particle cast the sensitive region of integration circuit parts of an apparatus.
SEU是由带电粒子投射到集成电路器件的敏感区域引起的，通常会导致器件内部寄存器内容的改变，或内存位翻转。Since you have already set the (simulated) register values appropriately, the ISR will process normally as if it was a real interrupt.
由于已经正确设置了（模拟）寄存器的值，ISR会正常进行处理，就仿佛它是一个真正的中断。Excess register declarations are harmless, however, since the word register is ignored for excess or disallowed declarations.
但是，过量的寄存器声明并没有什么害处，这是因为编译器可以忽略过量的或不支持的寄存器变量声明。Its successor was the 4040 processor (released in 1974), which had an expanded instruction set, program memory, register set, and stack.
其后面是4040处理器（1974发布），其具有扩展指令集、程序内存、寄存器集和堆栈。A register in the processor that contains the address of the next instruction to be executed. Also known as a program counter.
包含下一条要执行指令地址的处理器中的寄存器。也叫程序计数器。Probably by this point you have already been having trouble keeping up with which register holds what value.
到现在为止，您很可能已经碰到如何获悉哪个寄存器保存了什么值的问题。A set of edge-triggered (or equivalent) latches which jointly store the state of a binary value through a clock cycle is termed a register.
用一组沿触发（或等价的）锁存器在一个时钟周期内共同地存储一个以二进制数表示的状态，就称为寄存器。
