PowerPC 604

The PowerPC 604 is a Microprocesseur based on architecture RISC PowerPC, developed jointly by Apple, IBM and Motorola. It belongs to the second generation of PowerPC (or G2) with the PowerPC 602, PowerPC 603 and PowerPC 620.

History

Left at the same time as the PowerPC 603 intended for the portable machines and of line entry, PowerPC 604 was intended for the computers top-of-the-range. He was announced in April 1994, and for the first time was used in June 1995 (in the Power Macintosh 9500 of Apple). He equipped all the computers top-of-the-range Apple between 1995 and fine 1997, date or appeared the PowerPC G3.

Structure

All is made in PowerPC 604 to optimize the performances: it is once and half faster than the PowerPC 601 at equal frequency. The PowerPC 604 can carry out four instructions per cycle of clock. It has two calculating units whole, a whole unit multi-cycle a floating unit, a unit of loading/recording, a unit of connection and masks of instruction and data. Its floating unit manages the double-precision numbers. Contrary to the PowerPC 603 and 602, it can be used in systems Multiprocesseur S.
