Features
- Dual issue symmetric superscalar microprocessor with instruction prefetch optimized for system level price/performance:
- 466, 533, 600 MHz operating frequency.
- >1380 Dhrystone MIPS (2.3 DMIPS/MHz @ 600 MHz)
- High-performance system interface:
- 1600 Mbyte/s peak throughput.
- 200 MHz maximum frequency using HSTL signaling on the SysAD bus.
- Multiplexed address/data (SysAD) bus supports 1.5 V, 2.5 V, 3.3 V I/O logic.
- Processor clock multipliers 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9.
- Support for 64- or 32-bit interfaces.
- Integrated primary and secondary caches:
- All are 4-way set associative with 32-byte line size.
- 16 Kbytes instruction, 16 Kbytes data, 256 Kbytes on-chip secondary.
- Per line cache locking in primaries and secondary.
- Fast Packet Cache increases system efficiency in networking applications.
- High-performance floating-point unit - 1600 MFLOPS maximum:
- Single cycle repeat rate for common single-precision operations and some double-precision operations.
- Single cycle repeat rate for singleprecision combined multiply-add operations.
- Two cycle repeat rate for doubleprecision multiply and doubleprecision combined multiply-add operations.
- MIPS IV superset instruction set architecture:
- Data PREFETCH instruction allows the processor to overlap cache miss latency and instruction execution.
- Single-cycle floating-point multiplyadd.
- Integrated memory management unit:
- Fully associative joint TLB (shared by I and D translations).
- 64/48 dual entries map 128/96 pages.
- Variable page size.
- Embedded application enhancements:
- Specialized DSP integer Multiply-Accumulate instructions, (MAD/MADU) and three-operand multiply instruction (MUL).
- I&D Test/Break-point (Watch) registers for emulation & debug.
- Performance counter for system and software tuning & debug.
- 14 fully prioritized vectored interrupts - 10 external, 2 internal, 2 software.
