Introduction to the RAC6182
Hardware Architecture
CPU
The system processor is a QED RM5231 embodying the popular MIPS
4300 RISC architecture. The RM5231 has a 225MHz clock speed, 64bit internal registers and a built in floating point unit.
The system processor communicates directly with various memory
devices, a V320 bus controller, and a super I/O controller by way of a
32-bit system address and data bus.
The V320 bus controller manages system dynamic RAM for the 5231. It
also provides a bridge from the system bus to the PCI bus. In addition, it
provides system timers.
