CPU design is not normally what we do. But: We actually have 2 CPU designed and in use, an 8-bit and a 32-bit CPU. In this article we look at our 32-bit CPU, or rather how we are creating an enhanced version of it with very high Code Density

RISC-V: Dividing efficiently across different hardware
In previous blog posts I have described the division algorithms SEGGER implemented in emRun. However, which algorithm is best (in terms of code size, execution speed, or power efficiency) is very dependent on the target instruction set architecture (ISA) and the way the ISA is implemented in silicon. This article explains how we help to […]
Code Size: Squeezing more with linker outlining
My previous blog post covered the SEGGER Linker for RISC-V and the benefits provided by enhanced relaxation. This article continues to explore what SEGGER is doing with its linker technology, advancing what is typically possible.
Code size: Closing the gap between RISC-V and Arm for embedded applications
One of the issues faced by RISC-V developers is that the code density of the RISC-V instruction set for deeply embedded processors does not match that of Cortex-M with existing tools. That is changing with the product innovations SEGGER have developed, such as the recently-announced SEGGER Linker, capable of reducing code size by up to […]
Profiling and Code coverage on RISC-V using simulation
We recently licensed our Floating point library for RISC-V to a large international corporation. They asked not only for our functional verification suite, but also for a verification of the verification suite. A code coverage report showing that the entire code had been executed. While we know that all lines and every instruction have been […]
RISC-V adoption and 7th Workshop thoughts
You have probably seen that SEGGER attended the recent (7th) RISC-V Workshop. There we demonstrated J-Link support for RISC-V cores and Embedded Studio for RISC-V, our professional-grade IDE that (unsurprisingly) targets RISC-V processors. This post offers a personal view on RISC-V and a reflection on the workshop.
