# cpudb
[CPUID](https://en.wikipedia.org/wiki/CPUID) database derived from [InstLatx64](http://instlatx64.atw.hu).
[](https://pkg.go.dev/github.com/mmcloughlin/cpudb)
[](https://travis-ci.org/mmcloughlin/cpudb)
## Description
This package contains a list of CPUs from the [InstLatx64 database](https://github.com/InstLatx64/InstLatx64) along with their CPUID values. The [`CPU.CPUID()`](https://godoc.org/github.com/mmcloughlin/cpudb#CPU.CPUID) method enables you to perform CPUID queries on each processor, therefore enabling filtering to processors with specific capabilities.
## Example
The following [example](example/sha.go) shows how to search the database for CPUs supporting [SHA extensions](https://en.wikipedia.org/wiki/Intel_SHA_extensions).
[embedmd]:# (example/sha.go)
```go
package main
import (
"fmt"
"github.com/mmcloughlin/cpudb"
)
func main() {
for _, cpu := range cpudb.CPUs {
leaf, found := cpu.CPUID(7, 0)
if !found {
continue
}
if (leaf.EBX>>29)&1 == 0 {
continue
}
fmt.Printf("%s: %s\n", cpu.Alias, cpu.Type)
}
}
```
Output:
