Computing devices have instruction sets, which are their lowest, most primitive languages. Common instructions are those which cause two numbers to be added, multiplied or combined in other ways, as well as instructions that direct the processor where to look in memory for its next instruction. There are many other types of instructions. Assemblers...
Micro-architecture is the physical structure of a chip or chip component that makes it possible for a device to carry out the instructions. A given instruction set can be implemented by a variety of micro-architectures. The buses – data transfer channels – for Hexagon devices are 32 bits wide. That is, 32 bits of data can be moved from one part of ...
Operating systems
The port of Linux for Hexagon runs under a hypervisor layer ("Hexagon Virtual Machine") and was merged with the 3.2 release of the kernel. The original hypervisor is closed-source, and in April 2013 a minimal open-source hypervisor implementation for QDSP6 V2 and V3, the "Hexagon MiniVM" was released by Qualcomm under a BSD-style license.
Compilers
Support for Hexagon was added in 3.1 release of LLVM by Tony Linthicum. Hexagon/HVX V66 ISA support was added in 8.0.0 release of LLVM. There is also a non-FSF maintained branch of GCC and binutils.
Qualcomm Hexagon DSPs have been available in Qualcomm Snapdragon SoC since 2006.In Snapdragon S4 (MSM8960 and newer) there are three QDSP cores, two in the Modem subsystem and one Hexagon core in the Multimedia subsystem. Modem cores are programmed by Qualcomm only, and only Multimedia core is allowed to be programmed by user. They are also used in...
In March 2016, it was announced that semiconductor company Conexant's AudioSmart audio processing software was being integrated into Qualcomm's Hexagon. In May 2018 wolfSSL added support for using Qualcomm Hexagon.This is support for running wolfSSL crypto operations on the DSP. In addition to use of crypto operations a specialized operation load m...
There are six versions of QDSP6 architecture released: V1 (2006), V2 (2007–2008), V3 (2009), V4 (2010–2011), QDSP6 V5 (2013, in Snapdragon 800); and QDSP6 V6 (2016, in Snapdragon 820). V4 has 20 DMIPS per milliwatt, operating at 500 MHz.Clock speed of Hexagon varies in 400–2000 MHz for QDSP6 and in 256–350 MHz for previous generation of the archite...
Both Hexagon (QDSP6) and pre-Hexagon (QDSP5) cores are used in modern Qualcomm SoCs, QDSP5 mostly in low-end products. Modem QDSPs (often pre-Hexagon) are not shown in the table. QDSP5 usage: QDSP6 (Hexagon) usage:

This is a single instruction packet from the inner loop of a FFT: This packet is claimed by Qualcomm to be equal to 29 classic RISC operations; it includes vector add (4x 16-bit), complex multiply operation and hardware loop support. All instructions of the packet are done in the same cycle.
TSMC was founded in Taiwan in 1987 by Morris Chang as the world's first dedicated semiconductor foundry. It has long been the leading company in its field. [15] [16] When Chang retired in 2018, after 31 years of TSMC leadership, Mark Liu became chairman and C. C. Wei became Chief Executive.
Qualcomm MSM Interface. The Qualcomm MSM Interface is a proprietary interface for interacting with Qualcomm baseband processors and is a replacement for the legacy cellular extensions of the Hayes command set. [1] With mobile chipsets, communication between the application processor and the baseband processor happens through shared memory.
