ORCA
ORT82G5 FPSC Eight-Channel
System-Level Features
The Series 4 also provides system-level functionality by
means of its microprocessor interface, embedded sys-
tem bus, quad-port embedded block RAMs, universal
programmable phase-locked loops, and the addition of
highly tuned networking specific phase-locked loops.
These functional blocks allow for easy glueless system
interfacing and the capability to adjust to varying condi-
tions in today
’
s high-speed networking systems.
Microprocessor Interface
The MPI provides a glueless interface between the
FPGA and
PowerPC
microprocessors. Programmable
in 8-, 16-, and 32-bit interfaces with optional parity to
the
Motorola
PowerPC
860 bus, it can be used for
configuration and readback, as well as for FPGA con-
trol and monitoring of FPGA status. All MPI transac-
tions utilize the Series 4 embedded system bus at 66
MHz performance.
A system-level microprocessor interface to the FPGA
user-defined logic following configuration, through the
system bus, including access to the embedded block
RAM and general user-logic, is provided by the MPI.
The MPI supports burst data read and write transfers,
allowing short, uneven transmission of data through the
interface by including data FIFOs. Transfer accesses
can be single beat (1 x 4 bytes or less), 4-beat (4 x
4 bytes), 8-beat (8 x 2 bytes), or 16-beat (16 x 1 bytes).
System Bus
An on-chip, multimaster, 8-bit system bus with 1-bit
parity facilitates communication among the MPI, config-
uration logic, FPGA control, and status registers,
embedded block RAMs, as well as user logic. Utilizing
the
AMBA
specification Rev 2.0 AHB protocol, the
embedded system bus offers arbiter, decoder, master,
and slave elements. Master and slave elements are
also available for the user-logic and embedded back-
plane transceiver portion of the ORT82G5.
The system bus control registers can provide control to
the FPGA such as signaling for reprogramming, reset
functions, and PLL programming. Status registers mon-
itor INIT, DONE, and system bus errors. An interrupt
controller is integrated to provide up to eight possible
interrupt resources. Bus clock generation can be
sourced from the microprocessor interface clock, con-
figuration clock (for slave configuration modes), internal
oscillator, user clock from routing, or from the port clock
(for JTAG configuration modes).
Phase-Locked Loops
Up to eight PLLs are provided on each Series 4 device,
with four PLLs generally provided for FPSCs. Program-
mable PLLs can be used to manipulate the frequency,
phase, and duty cycle of a clock signal. Each PPLL is
capable of manipulating and conditioning clocks from
20 MHz to 420 MHz. Frequencies can be adjusted from
1/8x to 8x, the input clock frequency. Each programma-
ble PLL provides two outputs that have different multi-
plication factors but can have the same phase
relationships. Duty cycles and phase delays can be
adjusted in 12.5% of the clock period increments. An
automatic input buffer delay compensation mode is
available for phase delay. Each PPLL provides two out-
puts that can have programmable (12.5% steps) phase
differences.
Additional highly tuned and characterized, dedicated
phase-locked loops (DPLLs) are included to ease sys-
tem designs. These DPLLs meet ITU-T G.811 primary-
clocking specifications and enable system designers to
very tightly target specified clock conditioning not tradi-
tionally available in the universal PPLLs. Initial DPLLs
are targeted to low-speed networking DS1 and E1, and
also high-speed SONET/SDH networking STS-3 and
STM-1 systems. These DPLLs are not typically
included on FPSC devices and are not found on the
ORT82G5.
Embedded Block RAM
New 512 x 18 quad-port RAM blocks are embedded in
the FPGA core to significantly increase the amount of
memory and complement the distributed PFU memo-
ries. The EBRs include two write ports, two read ports,
and two byte lane enables which provide four-port
operation. Optional arbitration between the two write
ports is available, as well as direct connection to the
high-speed system bus.
Additional logic has been incorporated to allow signifi-
cant flexibility for FIFO, constant multiply, and two-vari-
able multiply functions. The user can configure FIFO
blocks with flexible depths of 512k, 256k, and 1k includ-
ing asynchronous and synchronous modes and pro-
grammable status and error flags. Multiplier capabilities
allow a multiple of an 8-bit number with a 16-bit fixed
coefficient or vice versa (24-bit output), or a multiply of
two 8-bit numbers (16-bit output). On-the-fly coefficient
modifications are available through the second read/
write port. Two 16 x 8-bit CAMs per embedded block
can be implemented in single match, multiple match,
and clear modes. The EBRs can also be preloaded at
device configuration time.
