Logic Block (LB)
The logic block is the basic building block of the PSI architec-
ture. It consists of a product term array, an intelligent product-
term allocator, and 16 macrocells.
Product Term Array
Each logic block features a 72 x 83 programmable product
term array. This array accepts 36 inputs from the PIM. These
inputs originate from device pins and macrocell feedbacks as
well as cluster memory and channel memory feedbacks. Ac-
tive LOW and active HIGH versions of each of these inputs are
generated to create the full 72-input field. The 83 product
terms in the array can be created from any of the 72 inputs.
Of the 83 product terms, 80 are for general-purpose use for the
16 macrocells in the logic block. Two of the remaining three
product terms in the logic block are used as asynchronous set
and asynchronous reset product terms. The final product term
is the Product Term clock (PTCLK) and is shared by all 16
macrocells within a logic block.
Product Term Allocator
Through the product term allocator,
Warp
software automati-
cally distributes the 80 product terms as needed among the 16
macrocells in the logic block. The product term allocator pro-
vides two important capabilities without affecting performance:
product term steering and product term sharing.
Product Term Steering
Product term steering is the process of assigning product
terms to macrocells as needed. For example, if one macrocell
requires ten product terms while another needs just three, the
product term allocator will
“
steer
”
ten product terms to one
macrocell and three to the other. On PSI devices, product
terms are steered on an individual basis. Any number between
1 and 16 product terms can be steered to any macrocell.
Product Term Sharing
Product term sharing is the process of using the same product
term among multiple macrocells. For example, if more than
one function has one or more product terms in its equation that
are common to other functions, those product terms are only
created once. The PSI product term allocator allows sharing
across groups of four macrocells in a variable fashion. The
software automatically takes advantage of this capability so
that the user does not have to intervene.
Note that neither product term sharing nor product term steer-
ing have any effect on the speed of the product. All steering
and sharing configurations have been incorporated in the tim-
ing specifications for the PSI devices.
