XMOS Venture

I started my venture into XMOS which is a fairly new company (2005) which develops Event-driven processors. These are some great products if your looking for speed and ram.

These are no where near a PIC/AVR micro in comparison. A PIC32 Can hit about 80Mhz with 1.5DMIPs/Mhz so thats about 120MIPs … And some AVR32 can hit 210 DMIPS @ 150 MHz which is great!!!!

With a single core XMOS XS1-L1 you can achieve 400MIPs of power. Even tho the Max I/O for a pin is 100mhz… Now the neat thing is XMOS is a multi-threading type MCU/CPU… Where i can have upto 8 processes running at the same time. The issue or drawback is that they share the power. Which isnt bad… If i only use 4 threads then its 100mhz per thread… so its like running 4 PIC micros at 100MIPS each and they can all communicate with each other with no extra hardware cost and minimal software intervention.

I cant really comment on AVR32 micros because i never really used AVRs…. You can also use all 8 threads if need be.. They would have about 50 MIPS each which is still great for the price of  a PIC18F MCU…Let me get back to the drawbacks…

There are no on-board peripherals such as UART, ADC,SPI etc… But the cool thing is most can be done in code. So you get what you want on a MCU… dont need SPI …. dont add it heh simple as that…

Now your probably thinking what if i need more threads …. they have a nice 2 Core MCU… XS1-G2. This puppy has 2 cores which allow up to 16 threads and the speed is also doubled to 800 MIPS, YES 800… so if you use all 16 threads ten you technically have 16 PICs running at 50MIPS… if you use 4 on each core then you have 8 PICs running at 100MIPS each…

Need more… greedy!!! But they can take care of you with a  4 Core XS1-G4.. as you may have guessed by now 32 Threads @ yes!!!! 1600MIPS …. You get the picture right!?!

You want to know what crazy about this whole thing… You can connect ICs together here with a XLINK which is a bridge for them. So you can call functions from 1 IC on another from any core…. Love them so far dont cha!!

Heh your gonna go nuts after this tho…. they also have a XMP-64 which is 64 Core dev tool… This bad boy has 16 * 4Core XMOS chips on it… It can run up to 512 Threads! 4MB RAM!! 25.6 GIPS!!! YES GIPS!!! aka 25.6 Billion Instructions Per Second….

Thats equivalent to : 0.0000000000390625 per cycle… or 39 Picoseconds…. but remember.. its equivalent not actual. Since all threads are running simultaneously.

Anyway. I hope you enjoyed this LONG post…. Thanks for reading and feel free to comment or correct me heh…
