ABSTRACT:
A high speed data processor obtains its speed through the efficient transfer of information over separate data and instruction busses, prefetching of instructions, dual working memory and architectural arrangements designed for maximum information transfer. The architecture of the data processor is such that data from any of several sources may be, either in combination or separately, channelled directly through an Arithmetic Logic Unit (ALU) so as to provide quick manipulation of the data since no extra iterations are needed in this movement. The processor uses two scratch pad or working memory areas. Both scratch pad memories communicate directly with the ALU so as to provide two operands, one from each memory and for the operation of the ALU. Two independent registers are provided which allow the linkage of computer words to obtain longer words thereby and a resulting higher precision. This linkage is accomplished by mapping and carrying the most significant bit over to the next sequentially mapped word. The invention also involves the use of a third independent register which may be directly channelled through the Arithmetic Logic Unit to set a memory address at a preselected value. This independent register is particularly useful in a real time mode of operation when the memory in the scratch pads must be dumped or temporarily stored in a non-volatile memory so as to erase the scratch pad memory permitting a higher priority task to utilize it.
