Altera Stratix III FPGAs

Altera(R) Stratix III FPGAs feature two new technologies that dramatically lower power while meeting high-performance requirements. Reduced power consumption is achieved by utilizing Altera’s innovative Programmable Power Technology, which maximizes performance where needed while delivering the lowest power elsewhere in the design. Programmable Power Technology enables every programmable logic array block (LAB), DSP block and memory block to independently operate at high-speed or low-power mode.

The PowerPlay feature in Quartus II software version 6.1 automatically analyzes the design and identifies which blocks are in the critical path and demand the highest performance, setting these to high-speed mode. All other logic is automatically put into low-power mode. The second power-optimizing feature, Selectable Core Voltage, provides the designer options to select either 1.1V for designs needing the highest performance or 0.9V for designs requiring minimum power consumption.

Stratix III devices offer the highest memory-to-logic ratio and DSP performance compared to any other FPGAs in the industry. To address a full range of high-end applications, three new Stratix III family variants are offered: one delivering balanced logic, memory and DSP resources for general-purpose applications, a second providing enhanced memory and DSP resources for memory- and DSP-intensive applications and a third offering integrated transceivers for high-bandwidth interface applications. Additionally, Altera provides a unique and risk- free migration path from Stratix III FPGAs to HardCopy(R) structured ASICs.

Stratix III Features
The Stratix III family architecture is based on the same FPGA fabric as the industry-leading Stratix II family featuring high-performance adaptive logic modules (ALMs). Working together, Stratix III FPGAs and Quartus II software offer the industry’s most innovative design methodology for improved productivity and performance. This enables designers to efficiently move their designs from development to production and meet both technical and business goals. Stratix III features include:

  • Programmable Power Technology: Enables every programmable logic array block (LAB), DSP block and memory block to independently operate at high-speed or low-power mode. The PowerPlay feature in Quartus II software automatically controls the mode of each block based on performance requirements.
  • Selectable Core Voltage: Enables designers to choose 1.1 V core voltage for high-performance applications or 0.9 V core voltage for the lowest power consumption.
  • Highest Performance: Stratix III devices are 25 percent faster than the prior generation and, at a minimum, provide a full speed grade advantage over any competing FPGA family.
  • Highest Density: Stratix III FPGAs bring a 2x density advantage over prior generation FPGAs and are the highest-density FPGAs in the industry.
  • Flexible I/O: Supporting over 40 I/O interface standards, Stratix III I/Os deliver industry-leading performance, flexibility and signal integrity.
  • External memory interfaces: Industry-leading memory interface performance with programmable I/O delay, programmable drive strength and slew rate, read/write leveling and 31 embedded registers per I/O for maximum DDR3 performance are new to Stratix III FPGAs.
  • Superior signal integrity: Stratix III FPGAs utilize increased power/ground to user I/O ratio, optimized signal return paths, adjustable slew rate control, staggered output delays and calibrated on-chip termination for best-in-class signal integrity.
  • Highest-performance DSP capability: Stratix III FPGAs deliver up to 300 times more multiplier/accumulator performance than the highest-performance digital signal processors, while providing lower power, smaller board footprint and lower overall system costs for equivalent performance.
  • TriMatrix memory: Stratix III TriMatrix memory includes three sizes of memory blocks, MLAB blocks, M9K blocks and M144K blocks, that enable higher memory bandwidth than any other FPGA memory architecture and up to 17 Mbits of memory performing at 600 MHz.
  • Design security: Stratix III devices are the only FPGAs with support for 256-bit Advanced Encryption Standard (AES) volatile and non-volatile security key to protect designs from copying, reverse engineering and tampering. This feature brings ease-of-use and industry-leading IP protection.
  • Quartus II PowerPlay software: PowerPlay optimization and analysis technology automatically analyzes designs and optimizes them for the lowest power while meeting users design constraints. No other power optimization software is as easy to use or effective in minimizing power.
  • Quartus II software v6.1 advanced design features: Quartus II software version 6.1 enables the highest levels of productivity and the fastest path to design completion for high-density FPGA designs with the TimeQuest timing analyzer, top-down and bottom-up incremental compilation and multiprocessor support.
