ARM has introduced its latest processor design \u2014 Cortex-A77. Like last year's Cortex-A76, this core is intended for high-end tasks in smartphones and various devices. The developer aims to increase the number of instructions executed per cycle (IPC). Clock speeds and power consumption remain roughly at the level of Cortex-A76.<\/p>\n

\"ARM<\/p>\n

Currently, ARM is focused on rapidly increasing the performance of its cores. According to its plans, starting with the Cortex-A73 from 2016 and up to the Hercules design in 2020, the company intends to increase CPU power by 2.5 times. The transitions from 16 nm to 10 nm and then to 7 nm have already allowed for higher clock speeds, and combined with the Cortex-A75 and then Cortex-A76 architecture, ARM estimates that a 1.8-fold increase in performance has been achieved to date. Now, the Cortex-A77 core will enable a 20% increase in performance at the same clock frequency due to the rise in IPC. Thus, a 2.5-fold increase by 2020 seems quite feasible.<\/p>\n

\"ARM<\/p>\n

Despite the 20% rise in IPC, ARM estimates that the power consumption of the A77 has not increased. The compromise here is that the die size of the A77 is about 17% larger than that of the A76 under the same technological norms. As a result, the cost of an individual core will rise slightly. Comparing ARM's achievement with industry leaders, it is worth noting that AMD achieved a 15% increase in IPC with Zen 2 compared to Zen+, while Intel's IPC values have remained roughly the same for many years.<\/p>\n

\"ARM<\/p>\n

The out-of-order execution window size has been increased by 25%, to 160 units, which allows the core to enhance calculation parallelism. Even with the Cortex-A76, there was a large branch target buffer, and in the Cortex-A77, it has been increased by an additional 33%, to 8 KB, which allows the branch prediction unit to effectively handle the growing number of parallel instructions.<\/p>\n

<\/center>
\n\"ARM<\/p>\n

An even more interesting innovation is the completely new 1.5KB cache that stores macro-operations (MOP) returned from the decoding module. The ARM processor architecture decodes instructions from the user application into smaller macro-operations, which are then broken down into micro-operations passed to the execution core. The MOP cache is used to reduce the impact of missed branches and resets, as the macro-operations are now stored in a separate block and do not require re-decoding \u2014 thus increasing the overall throughput of the core. In some workloads, the new block is an extremely useful addition to the standard instruction cache.<\/p>\n

\"ARM<\/p>\n

\"ARM<\/p>\n

A fourth ALU block and a second branching block have been added to the execution core. The fourth ALU increases the overall throughput of the processor by 1.5 times due to the capability of executing single-cycle instructions (such as ADD and SUB) and two-cycle integer operations like multiplication. The other two ALUs can only handle basic single-cycle instructions, while the last block is tasked with more complex mathematical operations such as division, accumulation multiplication, and so on. The second branching block within the execution core doubles the number of simultaneous branch transitions that the core can handle, which is beneficial in cases where two of the six dispatched commands involve branch transitions. Internal testing at ARM has shown a performance gain from utilizing this second branch transition block.<\/p>\n

\"ARM<\/p>\n

\"ARM<\/p>\n

Among other kernel changes are the addition of a second AES encryption pipeline, increased memory bandwidth, an enhanced next-generation data prefetching mechanism that improves energy efficiency while increasing DRAM system bandwidth, cache performance optimizations, and more.<\/p>\n

\"ARM<\/p>\n

\"ARM<\/p>\n

The greatest gains are observed in the Cortex-A77 for integer operations and floating-point calculations. This is confirmed by ARM's internal tests on SPEC, which showed performance increases of 20% and 35% in integer operations and floating-point calculations, respectively. Memory bandwidth improvements are in the range of 15\u201320%. Overall, the optimizations and changes in the A77 yield an average 20% performance increase compared to the previous generation. Thanks to newer technology standards like 7nm ULV, we can achieve additional advantages in final chips.<\/p>\n

\"ARM<\/p>\n

\"ARM<\/p>\n

ARM developed the Cortex-A77 to work in a 4+4 big.LITTLE configuration (4 powerful cores and 4 simple power-efficient ones). However, considering the increased area of the new architecture, many manufacturers may propose combinations of 1+3+4 or 2+2+4 for cost-saving purposes, which are already actively practiced, where only one or two cores will be full-fledged uncensored A77.<\/p>\n
