Configurable Logic Blocks
The basic building block of the Virtex-E CLB is the logic cell
(LC). An LC includes a 4-input function generator, carry
logic, and a storage element. The output from the function
generator in each LC drives both the CLB output and the D
input of the flip-flop. Each Virtex-E CLB contains four LCs,
organized in two similar slices, as shown in
Figure 5
In addition to the four basic LCs, the Virtex-E CLB contains
logic that combines function generators to provide functions
of five or six inputs. Consequently, when estimating the
number of system gates provided by a given device, each
CLB counts as 4.5 LCs.
Look-Up Tables
Virtex-E function generators are implemented as 4-input
look-up tables (LUTs). In addition to operating as a function
generator, each LUT can provide a 16 x 1-bit synchronous
RAM. Furthermore, the two LUTs within a slice can be com-
bined to create a 16 x 2-bit or 32 x 1-bit synchronous RAM,
or a 16 x 1-bit dual-port synchronous RAM.
The Virtex-E LUT can also provide a 16-bit shift register that
is ideal for capturing high-speed or burst-mode data. This
mode can also be used to store data in applications such as
Digital Signal Processing.
