Getting the value of CPU_COUNT

How to get the value of CPU_COUNT using SQL? The SQL below doesn't give me that.

SYS @ PRODDB SQL> show parameter cpu_count

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
cpu_count                            integer     36
SYS @ PRODDB SQL> select name, value from v$spparameter where name in ('cpu_count');

NAME                           VALUE
------------------------------ ------------------------------
cpu_count

1 row selected.

Thanks
