MIPS Tempts Hackers With Raspbery Pi-like Dev Board

DeviceGuru (1136715) writes "In a bid to harness the energy and enthusiasm swirling around today's open, hackable single board computers, Imagination Technologies, licensor of the MIPS ISA, has unveiled the Creator C120 development board, the ISA's counter to ARM's popular Raspberry Pi and BeagleBone Black SBCs. The MIPS dev board is based on a 1.2GHz dual-core MIPS32 system-on-chip and has 1GB RAM and 8GB flash, and there's also an SD card slot for expansion. Ports include video, audio, Ethernet, both WiFi and Bluetooth 4.0, and a bunch more. OS images are already available for Debian 7, Gentoo, Yocto, and Arch Linux, and Android v4.4 is expected to be available soon. Perhaps the most interesting feature of the board is that there's no pricing listed yet, because the company is starting out by giving the boards away free to developers who submit the most interesting projects."

Re:no price?

There's no price yet because they're giving away the first production run to people who are going to do interesting things with them. Unfortunately, this is a really bad time to do anything MIPS related (and I say this as someone who hacks on a MIPS IV compatible softcore and the LLVM MIPS back end). Imagination has just released the MIPS64r6 and MIPS32r6 specs. These are the biggest revisions to the MIPS ISA since MIPS III, which introduced 64-bit support. They've removed a load of legacy crap like the lwr and lwl instructions and the branch-likely instruction family and added things like compact (no delay slot) branch instructions, the requirement that hardware supports unaligned loads and stores (or, at least, that the OS traps and emulates them), and added much better support for PC-relative addressing. The result is a nice ISA, which is not backwards compatible with MIPS32r2 or MIPS64r2, the ISA that these boards use. Any investment in software for MIPS now is going to be wasted when products with the new ISA come out.
