How to run Linux SMP in QEMU on a MIPS64 Release 6 CPU

After publishing my initial article about QEMU, many of you have sent queries about running software written for MIPS64 Release 6 CPUs (MIPS64r6) in QEMU and also about the current state of the MIPSr6 multithreading module implemented in QEMU. I decided to answer these questions in this post and turn it into a tutorial on … Read more

Imagination, Imperas and Posedge Software present Linux bring up tutorial at 53rd DAC

Linux has become the general purpose operating system of choice for embedded systems, and is almost always supported for high-end SoCs developed by the semiconductor vendors. Most vendors use the open source Linux distribution, then build a custom distribution representing the device tree supported for the specific SoC, and including the necessary drivers for the … Read more

High-performance Hellfire hypervisor runs on MIPS Warrior MCUs

In an article I’ve published last year, I described how our new MIPS M-class Warrior CPUs have been designed for the security-driven requirements of next-generation connected processors. One of the unique features of MIPS microcontroller-class processors is the ability to support full hardware virtualization and multiple trusted execution environments (TEEs). For example, our latest M5150 … Read more

Why partners matter in today's semiconductor industry

I still remember when I entered the world’s biggest semiconductor company by value in 1980. This was an era where not invented here was the motto for many silicon vendors. And if they didn’t invent it, they made sure to convince everyone else that it wasn’t needed. Semiconductor companies also had a habit of doing … Read more

An overview of MIPS OCI: On Chip Instrumentation for advanced debug

MIPS OCI (On Chip Instrumentation) is a new flexible, modular debug architecture from Imagination for heterogeneous computing systems integrating multiple MIPS CPUs, and systems that combine MIPS CPUs with other CPU architectures. OCI comprises of modular interoperable debug IP components that can be selected to produce an optimal debug solution tailored to the needs of … Read more

PEZY licenses MIPS for “green” supercomputing

In a press release issued today PEZY Computing announced it is working on a MIPS64-based PEZY-SC2 family of many-core chips for supercomputers and HPC applications that will scale up to 4096 processing nodes. The 64-bit MIPS CPUs will act as the host processors for the system, making PEZY-SC2 the first generation of 64-bit HPC processors … Read more

QEMU: the open source MIPS64 Release 6 virtual platform

In this article I would like to present the current status of the MIPS Release 6 architecture implemented in upstream QEMU v2.4. This is one of the several major contributions from Imagination Technologies to the open source and QEMU communities in the last year. Read on to find out how MIPS Release 6 support has … Read more

MIPS in space: Inside JAXA’s Hayabusa-2 mission to asteroid rendezvous

A few days ago I brought you an exclusive interview with the New Horizons engineering team. The high-profile story presented the hardware and software systems that took the probe to Pluto and beyond. Today I’d like to revisit another important space mission called Hayabusa-2. Back in July, I wrote about the 64-bit MIPS CPU aboard … Read more

MIPS and open source: Linux 3.18 LTS and 4.3, emulating Linux MIPS in Perl, and more

It’s been awhile since my last update in June so I thought I’d give you an overview of some interesting projects I came across in my weekly hunt for MIPS-related developments from the software world. Linux 3.18.21 LTS brings improvements for MIPS Let’s start with the Linux 4.3 kernel which received “a hearty update” at … Read more

Debian 8 comes to Creator Ci20

We’re delighted to announce that after several months of work, a Debian 8 release candidate is finally ready for the Creator Ci20 microcomputer. Shipping of the new Creator Ci20 boards will also begin next week for customers who’ve pre-ordered the board from our online stores in Europe and North America. Introducing Debian 8 for Ci20 … Read more
