2.5x LOGIC DENSITY
Unlike FPGAs, Spacetime devices are capable of dynamically changing configurations at multi-GHz frequency. As a result, logic, memory and routing resources are all re-used multiple times per user cycle, enabling much higher density and shorter interconnect than FPGAs.

2.0x MEMORY DENSITY
FPGAs use large dual-port memory cells for their embedded memory blocks to support the multi-port functionality required in most communications and data processing applications. Spacetime memories provide greater multi-port flexibility while using twice denser single-port memory cells.

2.9x MEMORY PORTS
FPGA memories have 2 ports, whereas Spacetime memories have 8 or 16 ports. Many communications and data-processing applications can take advantage of such multi-ported memories which enable functions such as broadcast, muxing, de-muxing multiple channels of data, and 2-read/1-write register files.

3.7x DSP PERFORMANCE
The logic fabric on FPGAs run much more slowly than the hard multipliers, which limits practical DSP throughput to that of the slow fabric, rather than that of the fast multiplier. In contrast, with Spacetime, logic fabric, memories, and DSP blocks can all run at 1.6 GHz, which eliminates this bottleneck. The resulting high-speed pipelines in Spacetime are setting new standards for signal processing performance.
