Provides an instruction set for double-precision (64-bit) floating-point instructions that use the 64-bit GPRs. 36-bit real addressing Embedded vector and scalar single-precision floating-point APUs. Provide an instruction set for single-precision (32-bit) floating-point instructions. Memory management unit (MMU). Especially designed for embedded applications. Supports 4-Kbyte4-Gbyte page sizes. Enhanced hardware and software debug support Performance monitor facility that is similar to, but separate from, the device performance monitor The e500 defines features that are not implemented on this device. It also generally defines some features that this device implements more specifically. An understanding of these differences can be critical to ensure proper operations. 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 ranges or special transaction types (stashing). 1, 2, or 4 ways can be configured for stashing only. 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 Book E instructions or by externally mastered transactions. 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: 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 smaller-than-cache-line accesses. 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. Three inbound windows plus a configuration window on PCI and PCI Express Four outbound windows plus default translation for PCI and PCI Express DDR/DDR2 memory controller Programmable timing supporting DDR and DDR2 SDRAM 64-bit data interface MPC8544E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 8 2 Freescale Semiconductor
