Chapter 7
L2 Look-Aside Cache/SRAM
This chapter describes the organization of the on-chip L2/SRAM, cache coherency rules, cache line
replacement algorithm, cache control instructions, and various cache operations. It also describes the
interaction between the L2/SRAM and the e500 core complex.
7.1
The integrated 256-Kbyte L2 cache is organized as 1024 eight-way sets of 32-byte cache lines based on
36-bit physical addresses, as shown in
The SRAM can be configured with memory-mapped registers as externally accessible memory-mapped
SRAM in addition to or instead of cache. The L2 cache can operate in the following modes, described in
Section 7.2, “L2 Cache and SRAM
Freescale Semiconductor
•
•
•
Full cache mode (256-Kbyte cache).
Full memory-mapped SRAM mode (256-Kbyte SRAM mapped as a single 256-Kbyte block or
two 128-Kbyte blocks)
Partial SRAM and partial cache mode, in which one eighth, one quarter, or one half the total
on-chip memory can be allocated to 1 or 2 SRAM regions.
