PowerPC 750FX/GX: Outstanding Performance PowerPC for Power- Conscious Applications
The VMPC7 POWERENGINE features the latest PowerPC 750FX/GX microprocessor from IBM which delivers 700 MHz to 1 GHz performance for networking, storage, imaging, and other high-performance embedded applications. The PowerPC 750FX/GX fully complies with the PowerPC architecture. It is the first to combine IBM’s most advanced process technologies onto one chip, reducing power con- sumption by up to 50 percent or increasing performance by up to 30 percent. Manufactured in IBM’s advanced 0.13 micron process, the chip is the first to include copper inter- connects, silicon-on-insulator (SOI) transistors, and low-k dielectric insulation technologies.
The PowerPC 750FX and 750GX have respectively an inter- nal L2 cache capacity of 512 KB and 1 MB. The cache is two-way set associative; each way contains 4096 blocks and each block consists of two 32-byte sectors. Array read and write operations execute in one processor cycle. Moreover, the L1 data cache path to the 60x bus interface unit (BIU) and the L2 cache reload path to the L1 data cache are each 256 bits, a fourfold improvement compared with previous 7xx processors. Additional buffers between
the L1 data cache, L2 cache, and the BIU enable the processor to improve both latency and bandwidth by allow- ing two cache miss transactions to be active simultaneous- ly on the 60x bus. The memory management unit (MMU) has eight data and eight instruction block address transla- tion (BAT) registers to provide flexibility in defining larger blocks of memory for simpler management. Up to 4 GB of memory can be configured, eliminating the need for page- level translation in some embedded applications.
