AMD announced the Brazos-T platform on 9 October 2012. It comprised the 4.5-watt AMD Z-Series APU (codenamed Hondo) and the A55T Fusion Controller Hub (FCH), designed for the tablet computer market. [42] [43] The Hondo APU is a redesign of the Desna APU. AMD lowered energy use by optimizing the APU and FCH for tablet computers. [44] [45]
[245] [246] This was the first APU for embedded applications. These were followed by updates in 2013 and 2016. [247] [248] In May 2012, AMD Announced the AMD Embedded R-Series Accelerated Processing Unit. [249] This family of products incorporates the Bulldozer CPU architecture, and Discrete-class Radeon HD 7000G Series graphics.
AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm). AMD Zen 2 Family 17h – second generation Zen architecture based on 7 nm process, first architecture designed around chiplet technology. [3] AMD Zen 3 Family 19h – third generation Zen architecture in the optimised 7 nm process with major core redesigns. [4]
Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. [4] [5] [6] It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs. [7]
Heterogeneous System Architecture-enabled zero-copy through pointer passing. SIP blocks: Unified Video Decoder, Video Coding Engine, TrueAudio. [44] Dual-channel (2× 64 Bit) DDR3 memory controller. Integrated custom ARM Cortex-A5 co-processor [45] with TrustZone Security Extensions [46] in select APU models, except the Performance APU models. [47]
The system architecture allows any accelerator, for instance a graphics processor, to operate at the same processing level as the system's CPU. Among its main features, HSA defines a unified virtual address space for compute devices: where GPUs traditionally have their own memory, separate from the main (CPU) memory, HSA requires these devices ...
An apulet is a component of the Cell computer architecture consisting of a bundle comprising a data object and the code necessary to perform an action upon it. The Cell architecture calls for several APUs (Attached Processing Units) which do the primary processing of the system, under the control of a single Processing Element (PE).
Epyc (stylized as EPYC) is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture.Introduced in June 2017, they are specifically targeted for the server and embedded system markets.
