Samen met de nieuwe processorarchitectuur Cortex-A77<\/a><\/noindex> heeft het bedrijf ARM een grafische processor gepresenteerd, ontworpen voor mobiele systeem-on-a-chip oplossingen van de volgende generatie. De Mali-G77, die niet mag worden verward met de nieuwe displayprocessor Mali-D77<\/a><\/noindex>, markeert de overstap van de ARM Bifrost-architectuur naar Valhall.<\/p>\n

\"De<\/p>\n

ARM meldt een aanzienlijke toename van de grafische prestaties van de Mali-G77 \u2014 met 40% vergeleken met de huidige generatie Mali-G76. Dit is bereikt zowel door het productieproces als architectonische verbeteringen. De Mali-G77 kan tussen de 7 en 16 kernen hebben (in de toekomst mogelijk schaalbaar van 1 tot 32), waarbij elke kern bijna even groot is als die van de G76. Daarom zullen waarschijnlijk high-performance smartphones worden uitgerust met hetzelfde aantal GPU-kernen.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

In games kan een prestatietoename van 20% tot 40% worden verwacht, afhankelijk van het type grafische belasting. Gezien de resultaten van de populaire test Manhattan GFXBench zal het aanzienlijke voordeel van de nieuwe grafische processor ten opzichte van de huidige generatie ook de concurrent Qualcomm aanzetten tot aanzienlijke verbeteringen van de grafische prestaties van Adreno.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

Volgens ARM biedt de nieuwe Mali-G77-architectuur zelf een gemiddelde verbetering van 30% in energie-effici\u00ebntie of prestaties. De tweede generatie van de scalaararchitectuur ARM Valhall stelt de grafische processor in staat om 16 instructies per cyclus op een CU uit te voeren in vergelijking met acht in Bifrost (Mali-G76). Onder andere innovaties: volledig hardwarematig beheerd dynamisch instructieplanning en een geheel nieuwe instructieset met behoud van back-compatibiliteit met Bifrost. Ook is er ondersteuning toegevoegd voor de ARM AFBC1.3 compressie-indeling en andere innovaties (FP16 renderdoelen, gelaagd renderen en vertex shader outputs).<\/p>\n

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

\"De<\/p>\n

In Bifrost had 3 execution engines, each of which included an instruction cache, a register, and a Warp control block. The distribution across these three engines allowed the execution of 24 FMA instructions with 32-bit floating-point precision (FP32). In Valhall, each CU has only one execution engine, shared between two compute modules capable of processing 16 Warp commands per cycle, thus providing a total throughput of 32 FP32 FMA instructions per CU. Thanks to these architectural changes, the Mali-G77 can perform one-third more mathematical calculations in parallel compared to the Mali-G76.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

Additionally, each of these CU compute modules contains two new mathematical functional blocks. The new conversion module (CVT) handles basic integer, logical, branching, and conversion instructions. The special functions unit (SFU) accelerates operations for integer multiplication, division, square roots, logarithms, and other complex integer functions.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

De standaard FMA-module bevat verschillende instellingen die de uitvoering van 16 FP32-instructies per cyclus, 32 \u2014 FP16 of 64 \u2014 INT8 Dot Product ondersteunen. Deze optimalisaties kunnen een prestatieverbetering van maximaal 60% bieden in machine learning-toepassingen.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

Een andere belangrijke verandering in de Mali-G77 is de verdubbeling van de prestaties van de textuurmodule, die nu 4 bilineaire texels per cycle verwerkt vergeleken met twee eerder, en 2 trilineaire texels per cycle, wat snellere filtering van FP16 en FP32 mogelijk maakt.<\/p>\n

\"De<\/p>\n

\"De<\/p>\n

ARM has made a number of other changes, resulting in Mali-G77 and Valhall promising significant performance improvements for gaming workloads and machine learning tasks. Importantly, power consumption and chip area are maintained at Bifrost levels, promising the release of mobile devices with higher peak performance without increasing power consumption, heat dissipation, and size requirements.<\/p>\n
