Field-programmable object array
A field-programmable object array (FPOA) is a class of programmable logic device designed to be modified or programmed after manufacturing. They are designed to bridge the gap between ASIC and FPGA. They contain a grid of programmable silicon objects. Attrix range of FPOA contained three types of silicon objects Arithmetic and logical unit(ALUs), Register Files(RFs) and multiply-and-accumulate(MACs). Both the objects and interconnects are programmable.
==Motivation and history==
The device was intended to bridge the gap between FPGAs and ASICs. The design goal was to combine the programmability of FPGA and the performance of ASIC. FPGAs, although programmable, lack performance; they may only be clocked to few hundreds of megahertz and most FPGAs operated below 100 MHz. FPGAs did not offer deterministic timing and the maximum operating frequency depends on the design. ASICs offered good performance but they could not be modified and they were very costly. FPOA had a programmable architecture deterministic timing and gigahertz performance. FPOA is the brain child of Douglas Pihl who had this idea when working on a DARPA funded project.〔
("Computational vision: Testing MathStar’s field-programmable object arrays" ). EDN Networks,August 14, 2013.〕 He founded MathStar for producing FPOA in 1997 and the idea was patented in 2004. First FPOA prototypes were made in 2005 and first batch of FPOA chips were fabricated in 2006.〔(【引用サイトリンク】 Radiation Hardened FPOA for space processing. )
