Cores for interface acceleration
LSI Logic reckons it is the first semiconductor company to offer an ASIC implementation of the Serial ATA 1.0 high-speed interface technology with the introduction of two new cores
Both the LSI Logic Serial ATA 1.0 Link and Transport core and the 1.5Gbit/s Serial ATA 1.0 Physical Layer (PHY) core are now available to customers for easy integration into an ASIC. Processed in the LSI Logic Gflx 0.11-micron technology, these fundamental building blocks can be used along with the company's extensive CoreWare library of robust intellectual property.
The LSI Logic Serial ATA Link and Transport and PHY technologies comply with the Serial ATA 1.0 specification approved by the Serial ATA Working Group in mid-August 2001.
The Working Group expects the Serial ATA 1.0 specification to be widely adopted next year in disk drive, host bus adapter and computer chipset products as the evolutionary replacement of the Parallel ATA interface.
LSI Logic Link and Transport technology is available as a "synthesiseable", register transfer level (RTL) core and was demonstrated in Seagate's Serial ATA hard disk drive technology at IDF in Spring 2002.
The 1.5Gbit/s serial ATA PHY, also demonstrated at IDF Spring 2002, uses the widely adopted LSI Logic GigaBlaze serial transceiver core, which also supports Fibre Channel, Serial Attached SCSI, Gigabit Ethernet, PCI Express and InfiniBand transceiver standards.
Both technologies are available for integration into device-side and host-side ASIC solutions, eliminating the need for and cost of additional devices to bridge to Serial ATA from legacy interfaces.
"More than ever, storage customers are challenged with developing products that support a broad range of storage interfaces under increased time-to-market pressures.
LSI Logic recognises these challenges and, through its investments in high speed interface technologies, has become a world leader in this field", said David Jones, vice president and general manager of the LSI Logic Storage and Computing ASIC Division.
"Our customers will be able to reduce their time-to-market using our proven Serial ATA IP offerings, while also benefiting from the reduced investment necessary to support Serial ATA in their peripheral or host products".
Supporting the LSI Logic Serial ATA IP offerings, the LSI Logic Gflx technology, a 0.11-micron drawn gate (0.08-micron Leff) process, provides unprecedented flexibility.
Gflx offers seven different product modules, including high performance and low leakage transistors, performance and density libraries, mixed signal capability, application optimised I/O sets, metal options ranging from five to nine layers and a broad selection of memory compilers, to meet a multitude of customer and market requirements.
