Embedded e300 Core
The MPC5200B embedded e300 core is derived from Freescale’s (formerly Motorola) MPC603e family of Reduced Instruction Set Computer
(RISC) microprocessors. The e300 core is a high-performance, low-power implementation of the PowerPC superscalar architecture. The
MPC5200B e300 core contains:
(RISC) microprocessors. The e300 core is a high-performance, low-power implementation of the PowerPC superscalar architecture. The
MPC5200B e300 core contains:
•
16KBytes of instruction cache
•
16KBytes of data cache
Caches are 4-way set associative and use the Least Recently Used (LRU) replacement algorithm.
Four independent execution units are used:
1.
Branch Processing Unit (BPU)
2.
Integer Unit (IU)
3.
Load/Store Unit (LSU)
4.
System Register Unit (SRU)
