Description

The IDT79R4700-133G microprocessor, a member of the ORION family of IDT’s products, is designed to meet the performance requirements of several embedded applications. It delivers high-performance through high-speed pipelines, high-bandwidth caches and bus interface, 64-bit architecture, and more efficient control than its predecessor, the R4600.

Specifications and features

• 64-bit integer operations and 64-bit registers
• High-performance DSP capability, including high-speed floating point operations and integer Multiply-Accumulate operations-per-second
• 133 MIPS high-performance microprocessor with over 300,000 dhrystone (2.1)/sec capability at 133MHz (175 dhrystone MIPS)
• Low-power consumption with active power management and standby mode
• Upward software compatible with IDT RISController Family
• Large, efficient on-chip caches with over 1500MB/sec bandwidth from internal caches
• System interfaces of up to 67 MHz, which provide bandwidths up to 533 MB/S
