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 number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point.
