Ultra-low power image processor IC relies on Deeply Depleted Channel transistors
Manufactured on “CS250S” technology, which combines Fujitsu Semiconductor’s 55nm process with DDC technology, the IC boasts 30 percent lower power consumption and roughly twice the processing performance compared to existing products, say the companies. Fujitsu Semiconductor is SuVolta’s first licensee of the DDC technology. Since the collaboration was announced in June 2011, the companies have successfully brought up the DDC technology at the 65nm and 55nm nodes, meeting all production, yield and reliability requirements.
MB86S22AA is the latest product in the seventh-generation M-7M series of Milbeaut image processors, aimed at applications ranging from digital SLR cameras to smartphones. It includes features such as a new image processing algorithm with greatly improved optical correction capabilities, faster processing thanks to a newly developed Integrated Image Processor circuit and improved high dynamic range photograph quality using a JPEG-HDR format developed by Dolby Laboratories.
In combination, these advances enable roughly double the performance of existing products when processing still images. In terms of video processing, as well, proprietary algorithms make it possible for H.264/AVC compression and decompression on full-HD 30p and 60i video. This makes the new chip suitable for high-resolution, high-performance image processing in digital SLRs and high-end compact digital cameras.
SuVolta’s technology has been demonstrated to reduce total power consumption by up to 50 percent while matching the operating speed of the same circuit implemented in conventional transistors or increase operating speed by up to 35 percent while matching the power consumption of conventional designs. It also cuts transistor variability by up to 50 percent, improving memory performance and manufacturability. SuVolta’s technology uses planar, bulk CMOS, it can bring power-performance improvements to CMOS-based logic ICs from 90nm all the way to sub-20nm, as well as DRAM products.
