The DSC 9096 64-bit RISC Microprocessor is a high-performance, high-integration, low-power 64-bit processor that supports 64-bit integer and floating-point operations, has a 200MHz clock frequency, 64GB physical address space, and 179 or 208-pin packages.
The IDT79R4700 is a 64‑bit RISC microprocessor available at 80‑200 MHz with a 64 GB physical address space. It includes 16 KB instruction and data caches, a simple 5‑stage pipeline, and a flexible MMU with TLBs. The processor supports both 3.3 V and 5 V power supplies and is pin‑compatible with the IDT40xx family.
The datasheet details the integer and floating‑point execution units, cache organization, system interface (64‑bit address/data bus, 9‑bit command bus), and boot‑time configuration options. It also provides performance figures such as 260 Dhrystone MIPS and 100 MFLOP/s at 200 MHz.
