Series 4 FPGAs
Product Description
Architecture Overview
The
SRAM-based programmable devices from Lattice. It
includes enhancements and innovations geared toward
today’s high-speed systems on a single chip. Designed
with networking applications in mind, the Series 4 fam-
ily incorporates system-level features that can further
reduce logic requirements and increase system speed.
ORCA
Series 4 devices contain many new patented
enhancements and are offered in a variety of pack-
ages, and speed grades.
ORCA
Series 4 architecture is a new generation of
The hierarchical architecture of the logic, clocks, rout-
ing, RAM and system level blocks create a seamless
merge of FPGA and ASIC designs. Modular hardware
and software technologies enable system-on-chip inte-
gration with True Plug and Play design implementation.
The architecture consists of four basic elements: pro-
grammable logic cells (PLCs), programmable input/out-
put cells (PIOs), embedded block RAMs (EBRs), and
system-level features. A high-level block diagram is
shown in Figure 1. These elements are interconnected
with a rich routing fabric of both global and local wires.
An array of PLCs and its associated resources are sur-
rounded by common interface blocks (CIBs) which pro-
vide an abundant interface to the adjacent PIOs or
system blocks. Routing congestion around these criti-
cal blocks is eliminated by the use of the same routing
fabric implemented within the programmable logic core.
PICS provide the logical interface to the PIOs which
provide the boundary interface off and onto the device.
Also the interquad routing blocks
(hIQ, vIQ) separate the quadrants of the PLC array and
provide the global routing and clocking elements. Each
PLC contains a PFU, SLIC, local routing resources,
and con
fi
guration RAM. Most of the FPGA logic is per-
formed in the PFU, but decoders,
and 3-state buffering can be performed in the SLIC.
The PIOs provide device inputs and outputs and can
be used to register signals and to perform input demul-
tiplexing, output multiplexing, uplink and downlink func-
tions, and other functions on two output signals.
PAL
-like functions,
The Series 4 architecture integrates macrocell blocks
of memory known as EBR. The blocks run horizontally
across the PLC array and provide
fl
exible memory
functionality. Large blocks of 512x18 quad-port RAM
compliment the existing distributed PFU memory. The
RAM blocks can be used to implement RAM, ROM,
FIFO, multiplier, and CAM, typically without the use of
PFUs for implementation.
System-level functions such as a microprocessor inter-
face, PLLs, embedded system bus elements (located in
the corners of the array), the routing resources, and
con
fi
guration RAM are also integrated elements of the
architecture.
For Series 4 FPSCs, all PIO buffers and logic are
replaced by the embedded logic core on the side of the
device. The four PLLs on the right side of the device
(two in the upper right corner and two in the lower right
corner) are removed and the embedded system bus
extends into the FPSC section.
