Altera and AMPPSM Partner Northwest Logic Announce 266-MHz DDR SDRAM Controller
- The DDR SDRAM Controller is Optimized for Altera's APEX(tm) Devices
- New High Performance DDR SDRAM Controller Supports All Standard SDRAM and SGRAM Memory Types
- The DDR SDRAM Controller is Available With Interfaces to a Local Bus, PowerPC, Digital Video, and Altera MegaCore(tm) PCI cores
San Jose, Calif., January 10, 2000* Altera Corporation (NASDAQ: ALTR) and AMPPSM Partner Northwest Logic today announced the availability of a Double-Data Rate (DDR) Synchronous DRAM (SDRAM) Controller with 266-MHz performance. Northwest Logic, developer of the memory controllers, is a member of the Altera Megafunction Partners Program (AMPP), a program created in 1995 to offer programmable logic designers access to "best-in-class" IP cores. Northwest Logic's DDR SDRAM Controller is capable of operating at 266-MHz when implemented into an Altera EP20K400E device. Northwest Logic's DDR SDRAM Controller supports all standard SDRAM memory types and is available with interfaces to a Local Bus, Motorola PowerPC, Digital Video source and Altera MegaCore(tm) PCI cores. In addition, Northwest Logic offers a 133-MHz Single Data Rate SDRAM Controller with the same interface options. The controller also works with all standard Synchronous Graphics RAM (SGRAM).
"This announcement with Northwest Logic highlights the tremendous performance that can be achieved with Altera's PLDs and tools," said Luanne Stechert, Altera's AMPP program manager. "Altera and its AMPP partners are committed to continue delivering IP which enables our customers to develop a highly integrated System-on-a-Programmable Chip(tm) (SOPC) solution as quickly as possible."
"This design was made possible by the very high internal and I/O performance of Altera's APEX(tm) 20KE PLDs and the use of the internal PLL to minimize clock skew. These advantages combined, with the latest Quartus(tm) software, enabled us to very quickly modify our existing SDRAM Controller to support the latest high-speed DDR SDRAMs," according to Allan Douglas, president of Northwest Logic. "The result is a high-performance SDRAM Controller ideal for use in a variety of applications, including embedded computing and digital video."
About Northwest Logic's DDR SDRAM Controller
Northwest Logic has specifically designed its SDRAM Controllers to achieve high performance with minimal routing and pin constraints. The SDRAM Controller provides twice the throughput of other SDRAM Controllers by using sophisticated bank management and access cascading. Using the DDR SDRAM Controller at 266-MHz with a 64-bit memory bus width enables a sustained throughput of 2.1 GBytes/s. It also eliminates SDRAM control complexity by supplying a simple processor-style interface and providing automatic refresh. Northwest Logic's SDRAM Controller supports all standard SDRAM memory types and is available with interfaces to a Local Bus, PowerPC, Video Buffer and Altera PCI Cores. Netlist and source code license options are available. About the EP20K400E Device Northwest Logic's DDR SDRAM Controller has been optimized for the APEX 20KE architecture. The EP20K400E is the first member of the APEX 20KE family of SOPC devices. The EP20K400E device features 16,640 logic elements (LEs) and 212,992 RAM bits in embedded blocks, which can be configured as 1,664 macrocells. The high-performance EP20K400E PLD has 400,000 typical gates (1 million maximum system gates), up to 488 maximum user I/O pins, and operates at 1.8-, 2.5-, and 3.3-volts using MultiVolt(tm) I/O support.
Availability and Pricing
Northwest Logic's new DDR SDRAM Controller megafunction uses approximately 800 logic cells and is available now for $6,995 in encrypted netlist form. The SDRAM Controller is also available in source code (VHDL or Verilog) with a testbench. Customers can evaluate the SDRAM Controller for free prior to licensing as an Altera's OpenCore(tm) Netlist or a ModelSim Compiled Library.
