64-bit
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, a ...

In 2004 Freescale announced a new high performance core. Not much was known about it. It would be a multi core, multithreaded design using CoreNet technology, shared with the
e500mc core. It would be a three issue core with
double precision
Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point arithmetic, floating-point computer number format, number format, usually occupying 64 Bit, bits in computer memory; it represents a wide range of numeri ...
