Softwares
-
- HeteroCL: a domain-specific language and optimizing compiler for software-defined heterogeneous computing (CPU, FPGA, GPU, and Processing-in-Memory accelerators).
- T2S (temporal to spatial): a systolic array compiler that generates high-performance linear algebra and machine learning kernels for FPGAs.
- Dagger: a RPC framework powered by near-memory FPGA-based NIC. Dagger is designed for micro-services and featured ultra-low latency by offloading networking functions to FPGA.
- UpTune: a distributed auto-tuning framework. UpTune makes it much easier for users to search optimal parameters in their programs in a distributed environment with multiple worker machines.
- vTB: virtual-TPM enabled secure boot. vTB is a UEFI firmware driver that verifies the integrity of boot image to avoid malware injection. vTB is designed to emulate a TPM hardware module in software.
