Preliminary Data Sheet
August 2000
ORCA Series 4 FPGAs
Programmable Features
(continued)
— New register control in each PFU has two inde-
pendent programmable clocks, clock enables,
local set/reset, and data selects.
— New LUT structure allows flexible combinations of
LUT4, LUT5, new LUT6, 4-to-1 MUX, new
8-to-1 MUX, and ripple mode arithmetic functions
in the same PFU.
— 32 x 4 RAM per PFU, configurable as single- or
dual-port. Create large, fast RAM/ROM blocks
(128 x 8 in only eight PFUs) using the supplemen-
tal logic and interconnect cell (SLIC) decoders as
bank drivers.
— Softwired LUTs (SWL) allow fast cascading of up
to three levels of LUT logic in a single PFU
through fast internal routing which reduces routing
congestion and improves speed.
— Flexible fast access to PFU inputs from routing.
— Fast-carry logic and routing to all four adjacent
PFUs for nibble-, byte-wide, or longer arithmetic
functions, with the option to register the PFU
carry-out.
I
Abundant high-speed buffered and nonbuffered rout-
ing resources provide 2x average speed improve-
ments over previous architectures.
I
Hierarchical routing optimized for both local and glo-
bal routing with dedicated routing resources. This
results in faster routing times with predictable and
efficient performance.
I
SLIC provides eight 3-statable buffers, up to 10-bit
decoder, and PAL
1
-like and-or-invert (AOI) in each
programmable logic cell.
I
New 200 MHz embedded quad-port RAM blocks, two
read ports, two write ports, and two sets of byte lane
enables. Each embedded RAM block can be config-
ured as:
— One-512 x 18 (quad-port, two read/two write) with
optional built in arbitration.
— One-256 x 36 (dual-port, one read/one write).
— One-1K x 9 (dual-port, one read/one write).
— Two-512 x 9 (dual-port, one read/one write for
each).
— Two RAMS with arbitrary number of words whose
sum is 512 or less by 18 (dual-port, one read/one
write).
— Supports joining of RAM blocks.
— Two 16 x 8-bit content addressable memory
(CAM) support.
— FIFO 512 x 18, 256 x 36, 1K x 9 or dual 512 x 9.
— Constant multiply (8 x 16 or 16 x 8).
— Dual-variable multiply (8 x 8).
I
Built-in testability.
— Full boundary-scan (IEEE
2
1149.1 and Draft
1149.2 joint test access group (JTAG)).
— Programming and readback through boundary-
scan port compliant to IEEE Draft 1532:D1.7.
— TS_ALL testability function to 3-state all I/O pins.
— New temperature-sensing diode used to deter-
mine device junction temperature.
System Features
I
PCI local bus compliant.
I
Improved PowerPC
3
860 and PowerPC II high-speed
(66 MHz) synchronous MPI interface can be used for
configuration, readback, device control, and device
status, as well as for a general-purpose interface to
the FPGA logic, RAMs, and embedded standard-cell
blocks. Glueless interface to synchronous PowerPC
processors with user-configurable address space
provided.
I
New embedded
AMBA
4
specification 2.0 AHB sys-
tem bus (ARM
4
processor) facilitates communication
among the microprocessor interface, configuration
logic, EBR, FPGA logic, and embedded standard-cell
blocks. Embedded 32-bit internal system bus plus
4-bit parity interconnects FPGA logic, microproces-
sor interface (MPI), embedded RAM blocks, and
embedded standard-cell blocks with 100 MHz bus
performance. Included are built-in system registers
that act as the control and status center for the
device.
I
New
network phase-locked loops (PLLs) meet ITU-T
G.811 specifications and provide clock conditioning
for DS-1/E-1 and STS-3/STM-1 applications.
I
Flexible general-purpose programmable PLLs offer
clock multiply (up to 8x), divide (down to 1/8x), phase
shift, delay compensation, and duty cycle adjustment
combined. Improved built-in clock management with
programmable phase-locked loops (PPLLs) provide
optimum clock modification and conditioning for
phase, frequency, and duty cycle from 20 MHz up to
420 MHz. Each PPLL provides two separate clock
outputs.
I
Variable size bused readback of configuration data
capability with the built-in MPI and system bus.
I
Internal, 3-state, bidirectional buses with simple con-
trol provided by the SLIC.
