The Sequencer
J. S. Florentin · 1991
In the previous chapter, the data section of the simple computer covered in chapter 2 was integrated into the bit-slice chip. This leaves the control section of the computer. Even in a computer as simple as this it was easy to see that the control logic could be implemented using ROMs. In this particular example an inefficient implementation could be made by assuming that every instruction was less than, say, sixteen steps, and every different instruction started at a different sixteen-word boundary in a ROM. The outputs of the ROM were the signals that would control the system.
