Hi this is my first blog, I start with a part of the electricity that I find the more complex digital circuits and some programming. finite state machine (FSM) that consists of registers and counters coupled with a 4-bit full adder that can be controlled through firmware or sequential circuits.
left image shows a part of the circuit. Records A, m and M are shift registers 74178, is the 74LS193 counter to zero detector comparator was used 74LS85.
additional designs for this circuit were carrying memory and control unit.
The control unit has a register for storing the next state and show the present state, and a PROM with a C language program for the control board (which I will publish another post).
appreciate in advance any comment, I'm new to this in the blogs ...
