The system bus was a wider and faster 128-bit memory bus called the 6XX bus. It was designed to be a system bus for multiprocessor systems where processors, caches, memory and I/O was to be connected, assisted by a system control chip. It supports both 32- and 64-bit PowerPC processors, memory addresses larger than 32 bits, and NUMA environments. It was also used in POWER3, RS64 and 601, as well as 604-based RS/6000 systems (with a bridge chip). The bus later evolved into the GX bus of the POWER4, and later GX+ and GX++ in POWER5 and POWER6 respectively. The GX bus is also used in IBM's z10 and z196 System z mainframes. Contribution to the history of Unix at Bull (Interesting reading concerning the use of PowerPC 620 at Bull. In French) Extended family PowerPC 602 The PowerPC 602 was a stripped down version of PowerPC 603, specially made for game consoles by Motorola and IBM, introduced in February 1995. It has smaller L1 caches (4 KB instruction and 4 KB data), a single-precision floating-point unit and a scaled back branch prediction unit. It was offered at speeds ranging from 50 to 80 MHz, and drew 1.2 W at 66 MHz. It consisted of 1 million transistors and it was 50 mm² large manufactured in a 0.5 µm, CMOS process with four levels of interconnect. 3DO developed the M2 game console that used two PowerPC 602, but it was never marketed. Article at the CPUShack PowerPC 603q On October 21, 1996, the fabless semiconductor company Quantum Effect Devices (QED) announced a PowerPC 603-compatible processor named "PowerPC 603q" at the Microprocessor Forum. Despite its name, it did not have anything in common with any other 603. It was a from the ground up implementation of the 32-bit PowerPC architecture targeted at the high-end embedded market developed over two years. As such, it was small, simple, energy efficient, but powerful; equaling the more expensive 603e while drawing less power. It had an in-order, five-stage pipeline with a single integer unit, a double precision floating point unit (FPU) and separate 16 kB instruction and 8 kB data caches. While the integer unit was a brand new design, the FPU was derived from the R4600 to save time. It was 69 mm² small using a 0.5 µm fabrication process and drew just 1.2 W at 120 MHz. The 603q was designed for Motorola, but they withdrew from the contract before the 603q went into full production. As a result, the 603q was canceled as QED could not continue to market the processor since they lacked a PowerPC license of their own. PowerPC 613 "PowerPC 613" seems to be a name Motorola had given a third generation PowerPC. It supposedly was renamed "PowerPC 750" in response to Exponential Technology's x704 processor that was designed to outgun the 604 by a wide margin. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. PowerPC 614 Similar to PowerPC 613, the "PowerPC 614" might have been a name given by Motorola to a third generation PowerPC, and later renamed by the same reason as 613. It's been suggested that the part was renamed "PowerPC 7400", and Motorola even bumped it to the fourth generation PowerPC even though the architectural differences between "G3" and "G4" was small. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. PowerPC 615 The "PowerPC 615" is a PowerPC processor announced by IBM in 1994, but which never reached mass production. Its main feature was to incorporate an x86 core on die, thus making the processor able to natively process both PowerPC and x86 instructions. An operating system running on PowerPC 615 could either chose to execute 32-bit or 64-bit PowerPC instructions, 32-bit x86 instructions or a mix of three. Mixing instructions would involve a context switch in the CPU with a small overhead. The only operating systems that supported the 615 were Minix and a special development version of OS/2. It was 330 mm² large and manufactured by IBM on a 0.35 µm process. It was pin compatible with Intel's Pentium processors and comparable in speed. The processor was introduced only as a prototype and the program was killed in part by the fact that Microsoft never supported the processor. Engineers working on the PowerPC 615 would later find their way to Transmeta, where they worked on the Crusoe processor. PowerPC 625
