RISC-V processor trace support by UltraSoC, in growing development ecosystem

Five core vendors have already announced their support for the new trace specification, which is a key function for software developers using any processor; its delivery is, says UltraSoC, an important step forward in the development of the RISC-V ecosystem.


UltraSoC is a member of the RISC-V Foundation, and plays an active role in growth of the surrounding development ecosystem. Processor trace functionality – which allows the behaviour of a program to be viewed in detail, instruction-by-instruction – is a key must-have for software developers.


“RISC-V is a great architecture: but an architecture is not enough,” said Rupert Baines, UltraSoC CEO. “Customers need the whole ecosystem – an ecosystem that puts designers in control and empowers innovation. UltraSoC is aiming to play a major role in that with our debugging and development IP, and processor trace for RISC-V is a significant supporting pillar in that effort.”

UltraSoC is working with major RISC-V core vendors including Andes, Codasip, Roa Logic, SiFive and Syntacore, with the intention of submitting a proposed processor trace format to the RISC-V Foundation later in 2017 as the basis of the open source standard implementation.


UltraSoC’s implementation of RISC-V processor trace functionality will be available in Q42017.
