cores in the industry. They provide a full-duplex, point-to-point communications
channel for gigabit speed serial interfaces. Protocol independence enables the
high-speed serial interface. Applications for the cores include storage subsystems,
backplanes.
System Area Network (SAN) standard. Multiple GigaBlaze cores can be
integrated into a single ASIC. Combined with other LSI Logic standards-based
cores, such as Merlin鈩?Fibre Channel, the TinyRISC鈩?and MiniRISC鈩?/div>
processors, and PCI, the GigaBlaze core enables a completely new approach to
high-performance, single- chip solution for increased differentiation and reduced
chip count, power and cost. The third generation GigaBlaze transceiver is now
available in LSI Logic鈥檚 G11鈩?process technology, along with the G10 and 500K
process technologies.
Description
The GigaBlaze core consists of deserializer and serializer pattern and alignment
circuitry. The deserializer receives a serial gigabit speed input encoded data
stream and converts it into parallel data. This parallel data acts as an input for
any high-speed protocol handler. Likewise, encoded parallel data from the pro-
tocol handler can be transmitted at gigabit speeds after being converted into a ser-
ial stream by the serializer.
The core transmitter serializes the parallel data with clock information
embedded in it. The serialized output is a low-swing differential signal in NRZ
format. The receiver recovers data and the embedded clock from the serial data
stream, performs byte synchronization and presents parallel data with respect to
the recovered clock.
The LSI Logic CoreWare design program provides the complex building blocks,
proven design methodology, technology and application support necessary to build a
system on a chip, optimized uniquely for the target application. This single-chip
approach reduces overall system costs and accelerates time to market.
