Overview
1.1
Key Features
The following lists an overview of the MPC8641 key feature set:
Major features of the e600 core are as follows:
— High-performance, 32-bit superscalar microprocessor that implements the PowerPC ISA
— Eleven independent execution units and three register files
– Branch processing unit (BPU)
– Four integer units (IUs) that share 32 GPRs for integer operands
– 64-bit floating-point unit (FPU)
– Four vector units and a 32-entry vector register file (VRs)
– Three-stage load/store unit (LSU)
— Three issue queues, FIQ, VIQ, and GIQ, can accept as many as one, two, and three instructions,
respectively, in a cycle.
— Rename buffers
— Dispatch unit
— Completion unit
— Two separate 32-Kbyte instruction and data level 1 (L1) caches
— Integrated 1-Mbyte, eight-way set-associative unified instruction and data level 2 (L2) cache
with ECC
— 36-bit real addressing
— Separate memory management units (MMUs) for instructions and data
— Multiprocessing support features
— Power and thermal management
— Performance monitor
— In-system testability and debugging features
— Reliability and serviceability
MPX coherency module (MCM)
— Ten local address windows plus two default windows
— Optional low memory offset mode for core 1 to allow for address disambiguation
Address translation and mapping units (ATMUs)
— Eight local access windows define mapping within local 36-bit address space
— Inbound and outbound ATMUs map to larger external address spaces
— Three inbound windows plus a configuration window on PCI Express
— Four inbound windows plus a default window on serial RapidIO
— Four outbound windows plus default translation for PCI Express
— Eight outbound windows plus default translation for serial RapidIO with segmentation and
sub-segmentation support
