Tabula 是一家新兴无晶圆设计公司，号称开发具有3D架构的可编程逻辑奇器件，它的器件采用了称为Spacetime的架构，把逻辑单元、存储器、互连线等以3D方式组合，号称可以减少芯片面积， 并大大提升处理速度，据说intel 22nm代工厂会为其代工，这个新器件可以取代目前的FPGA吗？为什么？
以下是其介绍
A Spacetime device reconfigures on the fly at multi-GHz rates, executing each portion of a design in an automatically defined sequence of steps. Although manufactured using a standard CMOS process, Spacetime uses this ultra-rapid reconfiguration to make Time a third dimension, resulting in a 3D device with multiple layers or folds in which computation and signal transmission can occur. Each fold performs a portion of the desired function and stores the result in place. When some or all of a fold is reconfigured, it uses the locally stored data to perform the next portion of the function. By rapidly reconfiguring to execute different portions of each function, a 3D Spacetime device can implement a complex design using only a small fraction of the resources that would be required by an inherently 2D FPGA. A designer can realize all of the benefits of 3D within a familiar methodology using the Spacetime compiler that automatically maps standard RTL into Spacetime.Spacetime devices will provide significantly higher logic, memory and signal processing capabilities than FPGAs, and their much higher density makes them suitable for volume production.
