SiliconBlue Technologies Corporation was a United States based manufacturer of ultra-low power programmable logic devices (FPGAs) that the company calls "mobile FPGAs." The products target mobile and hand-held electronics applications that require low power and small physical size.〔 〕〔 〕 It was acquired by Lattice Semiconductor in 2011. SiliconBlue iCEcube2 development tools package includes ....〔 〕 * the Synplicity synthesis technology from Synopsys, * place and route tools that include timing-driven placement * static timing analyzer * graphic floorplanning and I/O assignment tools * power estimator * programming software SiliconBlue's mobileFPGA products are notable because their devices are the lowest power FPGAs to be marketed. In fact, their devices are low power and low cost enough to be used in cell phones. This is a significant advance in FPGA design and will potentially open up new markets to FPGAs where they had not been practical until now. ==Technology== The SiliconBlue iCE65 FPGA family is manufacted by TSMC using 65 nm process.〔 〕 The iCE65 FPGAs can be configured similar to other RAM-based FPGAs. Optionally, the FPGA can load its configuration from internal Nonvolatile Configuration Memory (NVCM). SiliconBlue's FPGA fabric is very common architecture based on a four-input look-up table (LUT4) and flip-flops. The iCE65 fabric includes RAM blocks, each with 4,096 memory bits, arranged as 256 locations, each location 16 bits wide. However the write port has write mask input port what allows any smaller width of memory to be emulated. The iCE65 'P' FPGAs also include an on-chip PLL/DCM; the iCE65 'L' FPGAs do not have a PLL. The only other special primitives are global buffers and warmboot primitive. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SiliconBlue Technologies」の詳細全文を読む スポンサード リンク
