1.6 R4000 Processor
System Interface
The R4000 processor supports a 64-bit System interface that can construct uniprocessor systems with a direct DRAM interface--with or without a secondary cache--or cache-coherent multiprocessor systems. The System interface includes:
- a 64-bit multiplexed address and data bus
- 8 check bits
- a 9-bit parity-protected command bus
- 8 handshake signals
The interface is capable of transferring data between the processor and memory at a peak rate of 400 Mbytes/second, when running at 50 MHz.
