[CCID News] Sun Microsystems announced that the UltrasParc IV chip is about to be launched. Based on the running speed of the IV chip server close to the UltraSparc IV server twice. The code of the new chip is "Panther", and Sun will disclose the details of the high-end processor on Tuesday.
Like the current Ultrasparc IV chip, UltrasParc IV is implanted with two kernels in the same piece of substrate, but the production process is more fine, ensuring higher cache speed and clock speed.
Dell Grand, director of the new chip development department, said that Ultrasparc IV will be asked in 2005, and the new chip operates the initial speed of 1.8GHz. The full load running analog speed up to 2GHz, and the fastest Ultrasparc IV chip The speed can only reach 1.2GHz. Sun plans to introduce the function of new chips in the Autumn Processor Forum held in San Jose, California.
After three years of struggle in the trough, Sun finally ushered in the turn, but the Ultrasparc chip family still faces the serious challenge of competitors. In addition to running in its own AIX version UNIX, IBM's POWER processor can run the Linux version of the Red Hat and Novell. HP works with Intel to launch the Itanium series chip. In addition, Intel's X86 chip and AMD's Opteron are getting stronger.
Sun uses dual-core strategies to approach the x86 and opneron chips. Although Sun has previously canceled the Ultrasparc V chip, continuing to develop a new SPARC series chip for code "Niagara" and "Rock", and also cooperate with Fujitsu companies to develop high-end SPARC servers.
Sun's long-term development plan continued until four years, Niagara servers and product products developed with Fujitsu will ask the city in 2006, while the Rock server will ask the city in 2008.
Ultrasparc IV is provided by Texas Instruments, but its process is different. Ultrasparc IV uses a 130 nanometer process, while IV uses a 90-nanometer process, and the integrated circuit on the chip has increased from 60 million to 300 million. Most of the new circuits are used for storage functions. UltrasParc iv has 16MB cache outside the chip, 8MB each core, and the IV chip itself has 2MB cache, and there are 32MB cache packages.
In order to improve the speed, UltraSparc IV can "prefetch" instructions, store the upcoming task instruction. The new chip has 8 signal paths to the chip transmission instruction, while the Ultrasparc IV is only one.
In addition, the data transmitted by the new signal paths is also protected by data corrective techniques. Current UltraSPARC III and IV, etc., can be upgraded to IV using an integrated board.
