ARM opens door to Cortex-A15 and A7 on 28nm
The packs (POPs) hold EDA data files that speed timing closure for single, dual and quad-core chips across various power/performance/area compromises.
“At the leading-edge 28nm HPM [high performance for mobile] and 28nm HP process variants, ARM is launching POPs for the Cortex-A9 core as well as for the Cortex-A7 and Cortex-A15,” said ARM. “Since the Cortex-A7 and Cortex-A15 cores are used in tandem as the big.LITTLE energy-efficient processing solution, the addition of POPs assures big.LITTLE implementations.”
According to ARM, its lead A15 28nm HPM POP licensee will tape-out “in the coming months”.
There are already A5 and A9 POPs for TSMC’s 40nm LP (low power) process, achieving 1GHz and 1.4GHz in production respectively claims ARM.
To these is added one for A7, plus variants for high-speed options on the 40nm LP process
A POP contains physical IP (intellectual property) logic libraries and memory instances tuned for the core and process, a benchmarking report on ARM results for the implementation, and an implementation guide that details the methodology used to achieve the result.
The POP for A15 on 28nm HP is still in work, the rest are available.Tags: 28nm, 40nm, A15, A5, A7, A9, ARM, Cortex, HP, HPM, LP, POP, TSMC
