Meet The Team
Thang Tran
Ph.D., Founder, CEO/CTO
Dr. Thang Tran is a distinguished microprocessor architect whose innovative work has advanced CPU technology over four decades. He led the design of the AndesCore NX27V—the first RISC‑V vector processor—which was successfully integrated into Meta’s high‑volume MTIA SoC. His contributions have shaped multiple generations of high‑performance, low‑power architectures across the industry.
He currently serves as Founder and Chief Technology Officer at Simplex Micro in Tustin, California, where he is developing next‑generation RISC‑V Vector Processor IP. His work draws on extensive research and patented technologies to redefine standards in high‑performance and deterministic computing. His recent acquisition of 20 patents and his sustained leadership in the field have solidified his reputation as one of the foremost experts in microprocessor architecture. He is inventor of over 190 patents.
Previously, he served as Chief Technology Officer at Condor Computing Corporation in Austin, Texas where he spearheaded the development of a groundbreaking out‑of‑order superscalar RISC‑V microprocessor.
Before Condor, he held senior roles at Andes Technology Corporation, where his work on advanced vector and DSP architectures contributed to award‑winning products recognized with the Hsinchu Science Park Innovative Product Award and ASPENCORE’s Outstanding Product Performance of the Year.
Earlier in his career, he was a Senior Microprocessor Architect and Manager at Texas Instruments, where he managed the micro‑architecture and RTL for the ARM Cortex‑A8 and ASIP technology. He also served as an AMD Fellow at AMD, where he played a key role in the development of the Athlon processors and other major initiatives.
Dr. Tran holds a PhD in Electrical and Computer Engineering and is a prolific speaker, serving as both a professor/lecturer and conference presenter.
