So imagine a very different kind of instruction word, probably long, many bits.
The numeric processor used a 256 bit-wide instruction word with seven "fields".
(b) The most-significant bit of an instruction word indicates the format.
I mean, it's incredibly complicated, as opposed to being a long instruction word which is much simpler and flatter.
But it is also necessary to link up these instruction words with other aspects of questions.
Fetching two instruction words at a time from memory enhanced the Ivory's performance.
The computer uses a full 24 bit instruction word and data word.
So you route some bits of the instruction word to the adder.
This was an unusually wide instruction word for the time.
The first 5 instruction words begin iteration 1 of the calculation.
