For example, the L1 cache
has a size of around 16 to 64 K and offers the highest level of performance.
As we have stated in Section 1, private L2 cache organizations suffer from lower L1 cache
miss latencies than shared L2 cache architectures at the expense of poor cache storage utilization.
2 L1 Cache
miss rates for the SPARC machine (OB--miss rate for the compilation-Optimized 16 x 16 Blocked; OL--miss rate for the compilation-Optimized 16 x 16 data Laid; Imp--percentage miss rate improvement of the data laid version over the blocked version) Grid Size OB OL Imp 33 x 32 0.
It includes 128 KB of L1 cache
and support for 512 KB to 8 MB of L2 cache.
Miss Rates for Procedure Placement with and without Hot-Cold Splitting.
Multiprocessors typically do not use a shared L1 cache
to exploit data sharing between parallel threads.
With these features as well as an L1 cache
, ST STM32F7 devices deliver the maximum theoretical performance of the ARM Cortex?
The units also feature 64 KB L1 cache
, 1 MB L2 cache, three Ethernet interfaces up to Gb speed, and two 64-bit PMCs on independent PCI buses.
The device has L1 cache
with 32 KB instruction and 32 KB data per core with parity protection, L2 cache with 1 MB per core with optional ECC and a MPX bus of up to 500 MHz.
4] analyze two design alternatives for the L1 cache
of a CMP.
They offer 64 K of unified instruction and data L1 cache
and Socket 7 motherboard compatibility for inexpensive deployment.
5 GHz, 667 MHz FSB, 4 MB L2 cache 479-pin [mu]FCBGA package, 2x 32KB L1 cache
and 4 MB L2 cache The processor is passive cooled with a fanless heatsink.
Based on the company's TMS320C64x+ core, the C6452 DSP offers double the L1 cache
memory and 40 percent more L2 cache than the C6415T, while including two gigabit Ethernet MAC ports and one gigabit switch.
