Altera have announcing launching the newly architected, high-density Stratix II family of FPGAs.
Featuring the adaptable FPGA architecture, Stratix II FPGAs are said to offer more than double the logic density in a single device and are 50% faster compared to first-generation Stratix devices.
This latest generation of high-density FPGA architecture is 25% more efficient compared to first-generation Stratix devices, allowing designers to pack more functionality into less logic area. The combination of the 90nm manufacturing process and an efficient architecture enables maximum integration, resulting in cost reductions when compared to previous high-density architectures.

| With up to eight inputs to the combinational logic block, one ALM can implement up to two independent functions each of varying widths, including any function of up to six inputs, and certain seven-input functions. Each ALM also contains two programmable registers, two adders, a carry chain, an adder tree chain, and a register chain that make more efficient use of device logic capacity.
This new logic building block delivers more logic capacity in a smaller physical area, provides faster device performance, and is 2.5 times more powerful than logic structures used in previous FPGA architectures. Stratix II devices have more than twice the logic of Stratix FPGAs with the equivalent of close to 180,000 logic elements.
Engineering samples of the first member of the Stratix II device family, the EP2S60 device, will be available in the second quarter of 2004.
