device inputs and outputs and can be used to register signals and to perform input demultiplexing, output multiplex-
ing, uplink and downlink functions, and other functions on two output signals. Large blocks of 512 x 18 block-port
RAM complement the existing distributed PFU memory. The RAM blocks can be used to implement RAM, ROM,
FIFO, multiplier, and CAM. Some of the other system-level functions include the MPI, PLLs, and the Embedded
System Bus (ESB).
PLC Logic
Each PFU within a PLC contains eight 4-input (16-bit) LUTs, eight latches/FFs, and one additional Flip-Flop that
may be used independently or with arithmetic functions.
The PFU is organized in a twin-block fashion; two sets of four LUTs and FFs that can be controlled independently.
Each PFU has two independent programmable clocks, clock enables, local set/reset, and data selects. LUTs may
also be combined for use in arithmetic functions using fast-carry chain logic in either 4-bit or 8-bit modes. The
carry-out of either mode may be registered in the ninth FF for pipelining. Each PFU may also be congured as a
synchronous 32 x 4 single- or dual-port RAM or ROM. The FFs (or latches) may obtain input from LUT outputs or
directly from invertible PFU inputs, or they can be tied high or tied low. The FFs also have programmable clock
polarity, clock enables, and local set/reset.
The SLIC is connected from PLC routing resources and from the outputs of the PFU. It contains eight 3-state, bidi-
rectional buffers, and logic to perform up to a 10-bit AND function for decoding, or an AND-OR with optional
INVERT to perform PAL-like functions. The 3-state drivers in the SLIC and their direct connections from the PFU
outputs make fast, true, 3-state buses possible within the FPGA, reducing required routing and allowing for real-
world system performance.
Programmable I/O
The Series 4 PIO addresses the demand for the exibility to select I/Os that meet system interface requirements.
I/Os can be programmed in the same manner as in previous ORCA devices, with the additional new features which
allow the user the exibility to select new I/O types that support High-Speed Interfaces.
Each PIO contains four programmable I/O pads and is interfaced through a common interface block to the FPGA
array. The PIO is split into two pairs of I/O pads with each pair having independent clock enables, local set/reset,
and global set/reset. On the input side, each PIO contains a programmable latch/Flip-Flop which enables very fast
latching of data from any pad. The combination provides for very low setup requirements and zero hold times for
signals coming on-chip. It may also be used to demultiplex an input signal, such as a multiplexed address/data sig-
nal, and register the signals without explicitly building a demultiplexer with a PFU.
On the output side of each PIO, an output from the PLC array can be routed to each output Flip-Flop, and logic can
be associated with each I/O pad. The output logic associated with each pad allows for multiplexing of output signals
and other functions of two output signals.
The output FF, in combination with output signal multiplexing, is particularly useful for registering address signals to
be multiplexed with data, allowing a full clock cycle for the data to propagate to the output. The output buffer signal
can be inverted, and the 3-state control can be made active-high, active-low, or always enabled. In addition, this 3-
state signal can be registered or nonregistered.
The Series 4 I/O logic has been enhanced to include modes for speed uplink and downlink capabilities. These
modes are supported through shift register logic, which divides down incoming data rates or multiplies up outgoing
data rates. This new logic block also supports high-speed DDR mode requirements where data are clocked into
and out of the I/O buffers on both edges of the clock.
The new programmable I/O cell allows designers to select I/Os which meet many new communication standards
permitting the device to hook up directly without any external interface translation. They support traditional FPGA
standards as well as high-speed, single-ended, and differential-pair signaling. Based on a programmable, bank-ori-
ented I/O ring architecture, designs can be implemented using 3.3V, 2.5V, 1.8V, and 1.5V referenced output levels.
