L2 cache

L2 cache

(Level 2 cache) A memory bank built into the CPU chip, packaged within the same module or built on the motherboard. The L2 cache feeds the L1 cache, which feeds the processor. L2 memory is slower than L1 memory. See cache.


L2 Cache Locations
Modern CPU chips have a built-in L2 cache; however, L2 caches have resided outside the CPU on earlier computers.

In case of L2 cache, bits belonging to cache indexing bits but outside the range of page offset bits determine the search space, so the average time used for scanning the search space would be half the time used to conduct one by one search over the whole space.

CPU_1 does not use L2 cache. L2 cache is a shared resource and CPU_0 owns this resource.

Constantinou et al [9] studied the impact of single thread migration in multi-cores with a shared L2 cache on the system performance, and highlighted the performance benefits from migrating the thread to the core it previously ran on and from cores remembering their predictor state since their previous activation, as better performance results from caches and predictors being warmed up.
It includes 64 KB L1 cache and 128 KB L2 cache. The board supports up to 1 GB of DDR SDRAM using an SO-DIMM socket.
The SCP/DCP-124P board supports 64-bit PMC and is powered by a Freescale Altivec-enhanced 7448 PowerPC processor running at either 1.0 or 1.2 GHz with one MB of internal ECC L2 cache that operates at core processor speed.
Configuration of the central server was as follows: HP Integrity rx6600, 4 processors / 8 cores / 16 threads, Dual-Core Intel Itanium 2 9050, 1.6 GHz, 32 KB(I) + 32 KB(D) L1 cache, 2 MB(I) + 512 KB(D) L2 cache, 24 MB L3 cache and 48 GB main memory.
The high-end of the two, the xw8400, unlike the xw6400, can support up to two Xeon 5000 processor (from 3.0 GHz to 3.73 GHz, 2-MB on-chip [L2] cache per processor core) or up to two Xeon 5100 processors (from 1.60 GHz to 3.00 GHz, 4 MB shared L2 cache per processor).
