More Custom Cores

At DAC, there was a special event for first-time DAC exhibitors to come talk to media folks. Kind of a way for them to get better visibility. One company in particular caught my eye – a small firm called Esencia. They’ve announced their EScala Design Platform.

It’s actually reminiscent of Target Compiler, which we covered about a year ago in a piece on multicore automation. The idea is that they analyze a C or C++ algorithmic program (that is, not C specifically structured for high-level synthesis) and then implement a custom architecture. They make use of the OpenRISC ISA, but then partition data flows, merge instructions, create custom instructions, and try to remove instructions if necessary.

They say they could also target a MIPS architecture because it’s standard RISC; ARM is less easy. But they’re not really looking in that direction because their interest lies in deeply-embedded algorithms that don’t need a full-up processor (while at the same time claiming to outperform those same processors).

Much of where they seem to have spent their attention is on moving data around: memory management and I/O bandwidth. For instance, they can do 32 32-bit datapaths (and make it look like a 1024-bit memory).

Their focus has been on multiple data flows for a single core, but claim to be multicore-capable as well.

Their actual tools are cloud-based (although they can do custom installations). The GUI runs on Flash within a browser, although they also have a command-line mode.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.

GaN for Humanoid Robots
Sponsored by Mouser Electronics and Infineon
In this episode of Chalk Talk, Eric Persson and Amelia Dalton explore why power is the key driver for efficient and reliable robot movements and how GaN technologies can help motor control solutions be more compact, integrated and efficient. They also investigate the role of field-oriented control in humanoid robotic applications and why the choice of a GaN power transistor can make all the difference in your next humanoid robot project!
