64-bit In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit CPUs and ALUs are those that are based on processor registers, address buses, or data buses of that size. A comp ...

Design

The e5500 is based on the e500mc core and adds some new instructions introduced in the Power ISA 2.06 specification, namely some byte- and bit-level acceleration; Parity, Population count, Bit permute and Compare byte. The FPU is taken straight from the PowerPC e600 core, which is a classic fully pipelined dual precision

unit running at full core speed and supports conversion between 64-bit floats and integers, effectively twice as fast as the FPU in e500mc. The e5500 also introduces an enhanced branch prediction unit with an 8-entry link stack. The e5500 core is the first 64-bit Power ISA core designed solely by Freescale and was introduced at Freescale Technology Forum in June 2010. Simulated models were available in July 2010, hard samples in late 2010 and full scale manufacturing the second half of 2011. Freescale have used the e700 and NG-64 monikers to refer to a very similarly specced core since 2004, but they are not the same product.
