— Double-precision floating-point APU. Provides an instruction set for double-precision (64-bit)
— 36-bit real addressing
— Embedded vector and scalar single-precision floating-point APUs. Provide an instruction set
— Memory management unit (MMU). Especially designed for embedded applications. Supports
— Enhanced hardware and software debug support
— Performance monitor facility that is similar to, but separate from, the device performance
256-Kbyte L2 cache/SRAM
— Flexible configuration
— Full ECC support on 64-bit boundary in both cache and SRAM modes
— Cache mode supports instruction caching, data caching, or both.
— External masters can force data to be allocated into the cache through programmed memory
— Eight-way set-associative cache organization (32-byte cache lines)
— Supports locking entire cache or selected lines. Individual line locks are set and cleared through
— Global locking and flash clearing done through writes to L2 configuration registers
— Instruction and data locks can be flash cleared separately.
— SRAM features include the following:
Address translation and mapping unit (ATMU)
— Eight local access windows define mapping within local 36-bit address space.
— Inbound and outbound ATMUs map to larger external address spaces.
DDR/DDR2 memory controller
— Programmable timing supporting DDR and DDR2 SDRAM
— 64-bit data interface
floating-point instructions that use the 64-bit GPRs.

ranges or special transaction types (stashing).
– 1, 2, or 4 ways can be configured for stashing only.
Book E instructions or by externally mastered transactions.
– I/O devices access SRAM regions by marking transactions as snoopable (global).
– Regions can reside at any aligned location in the memory map.
– Byte-accessible ECC is protected using read-modify-write transaction accesses for
– Three inbound windows plus a configuration window on PCI and PCI Express
– Four outbound windows plus default translation for PCI and PCI Express
smaller-than-cache-line accesses.
