MAX 3000A Programmable Logic Device Family Data Sheet
Parallel Expanders
Parallel expanders are unused product terms that can be allocated to a
neighboring macrocell to implement fast, complex logic functions.
Parallel expanders allow up to 20 product terms to directly feed the
macrocell OR logic, with five product terms provided by the macrocell and
15 parallel expanders provided by neighboring macrocells in the LAB.
The Altera development system compiler can automatically allocate up to
three sets of up to five parallel expanders to the macrocells that require
additional product terms. Each set of five parallel expanders incurs a
small, incremental timing delay (t
). For example, if a macrocell
PEXP
requires 14 product terms, the compiler uses the five dedicated product
terms within the macrocell and allocates two sets of parallel expanders;
the first set includes five product terms, and the second set includes four
product terms, increasing the total delay by 2 × t
.
PEXP
Two groups of eight macrocells within each LAB (e.g., macrocells 1
through 8 and 9 through 16) form two chains to lend or borrow parallel
expanders. A macrocell borrows parallel expanders from lower–
numbered macrocells. For example, macrocell 8 can borrow parallel
expanders from macrocell 7, from macrocells 7 and 6, or from macrocells
7, 6, and 5. Within each group of eight, the lowest–numbered macrocell
can only lend parallel expanders and the highest–numbered macrocell can
only borrow them.
Figure 4
shows how parallel expanders can be
borrowed from a neighboring macrocell.
