IDT RISController Series of Embedded Microprocessors. The RC32364 brings 64-bit performance levels to lower cost systems. High performance is achieved through the use of advanced techniques such as large on-chip two-way set-associative caches, a streamlined high-speed pipeline, high-bandwidth, and facilities such as early restart for data cache misses. Also, through IDT proprietary enhancements to the base MIPS architecture, the processor’s performance, in particular applications, is further extended. The RC32364 is the first member of a new processor family that uses IDT’s proprietary RISCore32300 CPU core. The RISCore32300 core continues IDT’s tradition of high-performance through high-speed pipelines, high-bandwidth caches, and architectural extensions that serve the needs of specific markets yet the RC32364 provides these capabilities in a low-cost, high-speed 32-bit enhanced MIPS architecture core, enabling a new level of price performance. Around the RISCore32300, the RC32364 integrates a fully RC5000 compatible memory management unit MMU , substantial amounts of efficient cache memory, an enhanced debug capability, digital signal processing DSP extensions, and a low-cost system interface. The resulting device is well suited to the needs of mid-range communications equipment, xDSL equipment, and consumer devices. Also, being upwardly software compatible with the RC3000 family, the RC32364 will serve in many of the same applications as well as support applications that require integer DSP functions. Device Performance RC32364 is rated at 175 dhrystone MIPS at 133MHz. The internal cache bandwidth is over GB/sec, with external bus bandwidth of 260MB/sec. Computational performance is further enhanced by the device’s DSP capability, which supports 66 Million multiply-accummulate MAC operations per second at 133MHz. The RISCore32300 uses a 5-stage pipeline, similar to the RISCore3000 and the RISCore4000 processor families. The simplicity of the pipeline enables the processor to achieve high frequency while minimizing device complexity, reducing both cost and power consumption. Because this pipeline is not sensitive to the data conflicts that slowdown super-scalar machines, an added benefit to this pipeline approach is that sustained actual performance is much closer to the theoretical maximum performance. The RISCore32300 integer execution unit implements the MIPS 32 ISA. The RISCore32300 thus implements a load/store architecture with single-cycle ALU operations logical, shift, add, subtract and an autonomous multiply/divide unit. The 32-bit register resources include 32 general-purpose orthogonal integer registers, the HI/LO result register for the integer multiply/divide unit, and the program counter. RISCore32300 CPU core features include: x MIPS IV prefetch operations, with various innovative hint subfields High-order multiplexed address and data bits. Regardless of system byte ordering, AD 31 is the MSB of the address. AD 3:0 Size 3:0 /Data 3:0 Valid sizes for the RC32364 are as follows: Addr 3:2 ADS Size 3 Size 2 Size 1 Size 0 0 1 0 1 0 Transfer Width 16 bytes 1 byte 2 bytes 3 bytes 4 bytes Other encodings allow future generations to service other transfer sizes.
