San Jose, Calif.Renesas Technology America Inc. announced an enhanced SH7786 dual-core 32-bit processor, a second-generation version fabricated with a 65-nm process for high-performance multimedia equipment such as car navigation systems.
The SH7786 processor delivers processing performance of up to 1,920 million instructions per second (MIPS) when operating at 533MHz. This member of the SuperH family incorporates a DDR3-SDRAM memory interface for high-speed data transfers: up to 4.27Gbytes per second (4.27GB/s). Yet the device uses less power than the previous version, which was fabricated with a 90-nm process.
The SH7786 integrates a dedicated 32-bit bus operating at 533MHz for connecting to DDR3-SDRAM (Double Data Rate 3-Synchronous DRAM) with an operating voltage of 1.5V, enabling the fast 4.27GB/s transfer rates. (Earlier 90-nm SH7786 products were compatible with DDR2-SDRAM with an operating voltage of 1.8V.) In addition, the 65-nm processor's multiple PCI Express bus interfaces support large-volume data transfers with data throughput up to 800MB/sec. This makes it possible to implement sophisticated drawing capabilities such as smoothing out complex and real 3D graphic images.
