Epiphany – A breakthrough in parallel processing
The Epiphany multicore coprocessor is a scalable shared memory architecture, featuring up to 4,096 processors on a single chip connected through a high-bandwidth on-chip network. Each Epiphany processor core includes a tiny high performance floating point RISC processor built from scratch for multicore processing, a high bandwidth local memory system, and an extensive set of built in hardware features for multicore communication. The Epiphany coprocessor is ANSI-C and OpenCL programmable and works in cooperation with standard microprocessors to provide unprecedented level of real-time processing to performance and power constrained mobile devices like smartphones and tablet computers, as well as improving performance levels for an array of other parallel computing platforms.

- Are your customers complaining that their mobile device runs out of battery too fast?
- Do you lack the money, team, or time needed to convert your floating point C-based reference application to a fixed point FPGA/ASIC hardware implementation?
- Do you have a killer app in mind that won’t become practical until 2016 based on existing mobile processor roadmaps?
High Performance Applications:
- Would you benefit from reducing your processing latencies to microseconds and still being able to program in ANSI-C?
- Do you lack the electrical and cooling infrastructure needed to operate a state of the art high performance system?
- Are you only seeing 10-15% of the advertised maximum performance of your current vendor’s manycore solution?
- Are you frustrated with the steep learning curve and proprietary development environments of existing floating pointaccelerator technologies?
