Solbourne Computer Corp, Longmont, Colorado says that its 64-bit implementation of the Sun Microsys tems Sparc CPU, developed with its majority shareholder Matsushita El ectric Industrial Co, will be cloc ked at 40MHz, and the 1m transistor part will include integrated integer and floating-point processors, on chip memory management, and separate instruction and data caches. The firm is promising a 20 MIPS worksta tion using the part in the middle of next year, although it claims that the chip has the potential to deliv er 40 MIPS and 20 M-FLOPS. The chip will be used only by Matsushita and Solbourne, and not offered outside.
