『Intel Edison Kit for Arduino』 を買ってみました。
性能とか、いろいろといじくって遊んでみようと思います。

まずは、誰しもが最初に確認するであろう、/proc/cpuinfo を見てみます。

組み込み系と同じく、U-Boot でした。grub かと思ってました。

ただ、barebox に慣れた身には U-Boot の原始的な環境は辛いものがあります。

フィボナッチ数列でベンチマーク のベンチマークを行ってみます。

fib.js

function fib(n) {
    if (n < 2) return n;
    return fib(n - 2) + fib(n - 1);
}
 
console.log(fib(38));

root@EdisonArduino:~# time node fib.js

real	0m 10.71s
user	0m 10.79s
sys	0m 0.19s

node,js でのフィボナッチ数列ベンチマークは、ARM Cortex-A8 1GHz のほうが高速でした。
