... LAN switches – Routers – Color printers Description The IDT79R4700 64-bit RISC Microprocessor is both software and pin-compatible with the R4 capabilities, the R4700 provides more computational power and data movement bandwidth than is delivered to typical embedded systems by 32-bit processors. The R4700 is upwardly software compatible with the IDT79R3000 microprocessor family, including the IDTRISController ™ ...

... IDT79R4700 The RC4700 processor also supports a supervisor mode in which the virtual address space is 256.5GB (2.5GB in 32-bit address mode), divided into three regions that are based on the high-order bits of the virtual address. If the RC4700 is configured for 64-bit virtual addressing, the virtual address space layout is an upwardly compatible extension of the 32-bit virtual address space layout ...

... IDT79R4700 Because the cache is virtually indexed, the virtual-to-physical address translation occurs in parallel with the cache access, further increasing performance by allowing these two operations to occur simul- taneously. The tag holds a 24-bit physical address and valid bit and is parity protected. The instruction cache is 64-bits wide and can be refilled or accessed in a single processor cycle ...

... IDT79R4700 ValidOut* and ValidIn* are used by the RC4700 and the external device respectively to indicate that there is a valid command or data on the SysAD and SysCmd buses. The RC4700 asserts ValidOut* when it is driving these buses with a valid command or data, and the external device drives ValidIn* when it has control of the buses and is driving a valid command or data ...

... IDT79R4700 Thermal Considerations The RC4700 uses special packaging techniques to improve the thermal properties of high-speed processors. The RC4700 is packaged using cavity down packaging in a 179-pin PGA package, and a 208-lead QFP package. These packages effectively dissipate the power of the CPU, increasing device reliability. ...
