The Fujitsu FR-V (Fujitsu RISC-VLIW) is a 1-8 way VLIW (up to 256 bit) 32-bit RISC multi-core processor family presented in 1999.[1]
The family started with the FR-500, includes FR-400, FR-450, FR-550 and FR1000 architecture processors, can run Linux and is also supported by the Softune Integrated development environment and the GNU Compiler Collection.
It is often used for image processing or video processing with most variants including a dual 16-bit media-processor.

Technology
The 2005 presented FR1000 uses a core with 8-way 256-bit VLIW (MIMD) filling its superpipeline as well as a 4-unit superscalar architecture, further increasing its peak performance of each core to up to 28 instructions per clock cycle. Due to the used 4-way single instruction, multiple data (SIMD) vector processor-core, it counts to up to 112 data-operations per cycle and core, of which Fujitsu claims nearly half of them are usable in applications using a single-chip with 4-cores (51.2 GOPS at 266 MHz, presented 2005).[2] The included 4-way vector processor units are a 32-bit integer arithmetic logic unit and floating point unit as well as a 16-bit media-processor, which can process up to twice the operations in parallel.
Some processors have integrated MMU.
Applications
They are used to built the Milbeaut signal processors specialized for image processing,[3][4] with the newest version additionally including an FR-V based HD video H.264 codec engine.[5][6]
The Milbeaut image engines are included in the Leica S2,[7] Nikon DSLRs (see Nikon EXPEED), some Pentax K mount[8] cameras and for the Sigma True-II processor.[9]
