Features
◆
High performance 64-bit microprocessor, based on the
RISCore4000
– Minimized branch and load delays, through streamlined
5-stage scalar pipeline.
– Single and double precision floating-point unit
– 125 peak MFLOP/s at 250 MHz
– 330 Dhrystone MIPS at 250 MHz
– Flexible RC4700-compatible MMU
– Joint TLB on-chip, for virtual-to-physical address mapping
◆
On-chip two-way set associative caches
– 16KB instruction cache (I-cache)
– 16KB data cache (D-cache)
◆
Optional I-cache and D-cache locking (per set), provides
improved real-time support
◆
Enhanced, flexible bus interface allows simple, low-cost
design
– 64-bit Bus Interface option, 1000MB/s bandwidth support
– 32-bit Bus Interface option, 500MB/s bandwidth support
