■ DSP intellectual property (IP) cores
■ DSP Builder interface to The Mathworks Simulink and Matlab
design environment
■ DSP Development Kit, Cyclone II Edition
Cyclone II devices include a powerful FPGA feature set optimized for
low-cost applications including a wide range of density, memory,
embedded multiplier, and packaging options. Cyclone II devices support
a wide range of common external memory interfaces and I/O protocols
required in low-cost applications. Parameterizable IP cores from Altera
and partners make using Cyclone II interfaces and protocols fast and easy.
The Cyclone II device family offers the following features:
■ High-density architecture with 4,608 to 68,416 LEs
● M4K embedded memory blocks
● Up to 1.1 Mbits of RAM available without reducing available
logic
● 4,096 memory bits per block (4,608 bits per block including 512
parity bits)
● Variable port configurations of ×1, ×2, ×4, ×8, ×9, ×16, ×18, ×32,
and ×36
● True dual-port (one read and one write, two reads, or two
writes) operation for ×1, ×2, ×4, ×8, ×9, ×16, and ×18 modes
● Byte enables for data input masking during writes
● Up to 260-MHz operation
■ Embedded multipliers
● Up to 150 18- × 18-bit multipliers are each configurable as two
independent 9- × 9-bit multipliers with up to 250-MHz
performance
● Optional input and output registers
■ Advanced I/O support
● High-speed differential I/O standard support, including LVDS,
RSDS, mini-LVDS, LVPECL, differential HSTL, and differential
SSTL
● Single-ended I/O standard support, including 2.5-V and 1.8-V,
SSTL class I and II, 1.8-V and 1.5-V HSTL class I and II, 3.3-V PCI
and PCI-X 1.0, 3.3-, 2.5-, 1.8-, and 1.5-V LVCMOS, and 3.3-, 2.5-,
and 1.8-V LVTTL
● Peripheral Component Interconnect Special Interest Group (PCI
SIG) PCI Local Bus Specification, Revision 3.0 compliance for 3.3-V
operation at 33 or 66 MHz for 32- or 64-bit interfaces
● PCI Express with an external TI PHY and an Altera PCI Express
