Figure 1. ispXPGA Block Diagram
Programmable Function Unit
The Programmable Function Unit (PFU) is the basic building block of the ispXPGA architecture. The PFUs are
arranged in rows and columns in the device with PFU (1,1) referring to (row 1, column 1). Each PFU consists of
four Con
fi
gurable Logic Elements (CLEs), four Con
fi
gurable Sequential Elements (CSEs), and a Wide Logic Gen-
erator (WLG). By utilizing these components, the PFU can implement a variety of functions. Table 3 lists some of
the function capabilities of the PFU.
There are 57 inputs to each PFU and nine outputs. The PFU uses 20 inputs for logic, and 37 inputs drive the con-
trol logic from which six control signals are derived for the PFU.
