ORCA Series 4 FPGAs
System Features
(continued)
I
Meets universal test and operations PHY interface for ATM (UTOPIA) Levels 1, 2, and 3. Also meets proposed
specifications for UTOPIA Level 4 for 10 Gbits/s interfaces.
I
New clock routing structures for global and local clocking significantly increases speed and reduces skew
(<200 ps for OR4E4).
I
New local clock routing structures allow creation of localized clock trees anywhere on the device.
I
New DDR, QDR, and ZBTmemory interfaces support the latest high-speed memory interfaces.
I
New 2x/4x uplink and downlink I/O shift registers capabilities interface high-speed external I/Os to reduced inter-
nal logic speed.
I
ORCA Foundry 2000 development system software. Supported by industry-standard CAE tools for design entry,
synthesis, simulation, and timing analysis.
Table 2. System Performance
1. Implemented using 8 x 1 multiplier mode (unpipelined), register-to-register, two 8-bit inputs, one 16-bit output.
2. Implemented using two 32 x 4 RAMs and one 12-bit adder, one 8-bit input, one fixed operand, one 16-bit output.
3. Implemented using 8 x 1 multiplier mode (fully pipelined), two 8-bit inputs, one 16-bit output (seven of 15 PFUs
contain only pipelining registers).
4. Implemented using 32 x 4 RAM mode with read data on 3-state buffer to bidirectional read/write bus.
5. Implemented using 32 x 4 dual-port RAM mode.
6. Implemented in one partially occupied SLIC, with decoded output setup to CE in the same PLC.
7. Implemented in five partially occupied SLICs.
