PIB 21: Implementing Logic with the Embedded Array in FLEX 10K Devices
The size of the state machine’s required memory is calculated from its
memory width and memory depth. Memory width is a function of the
number of outputs and the number of states; memory depth is a function
of the number of inputs and the number of states.
Memory width = Q + C (log
2
(S))
Memory depth = 2
(D + C ( log
2
(S)))
where Q = Number of outputs
C = Ceiling (The ceiling function returns the next highest integer
value, i.e., ceiling (1.0) = 1, ceiling (1.1 ... 1.9) = 2.)
S = Number of states
D = Number of inputs
If the required memory space is larger than can fit into one EAB, the
MAX+PLUS II development software can cascade multiple EABs to create
the required memory space.
Limited-Transition State Machine
A limited-transition state machine can implement more states in a given
amount of logic, but consequently cannot have very complex transitions
between states.
Figure 9
shows a hold-or-transition state diagram for a
limited-transition state machine.
Figure 9. Hold-or-Transition State Diagram
An EAB can control whether a limited-transition state machine remains in
the current state or transitions to the next state. First, the inputs to the state
machine drive the combinatorial logic implemented in the logic array. The
combinatorial logic controls the Count Enable (
CNT_EN
) of the counter.
Then, the outputs of the counter drive the EAB inputs, which produce the
outputs for that state. For example, an 8-bit counter with one EAB can
implement an 8-output, 256-state state machine. See
Figure 10
