Ray tracing levels aims for clarity with imaging graphics SoCs

2020-09-24 18:17 Embedded.com Nitin Dahad

All ray tracing capabilities on the market today are not equal. With more imaging graphics systems on chip (SoCs) using ray tracing acceleration, Imagination Technologies has developed a Ray Tracing Levels system to help developers and original equipment manufacturers (OEMs) to clearly understand the various different ray tracing implementations in currently being used and for the future.

The system is not necessarily aiming to be an industry benchmark, but an aid for developers to identify the vastly varying ray tracing capabilities and help compare like with like. The Ray Tracing Levels system identifies increasingly advanced stages of ray tracing acceleration, across a range of architectures, not just Imagination’s PowerVR ray tracing, with each level defining higher performance and better hardware utilization.

The grading system, from level 0 to level 5, translates to successively greater real-world ray tracing performance levels with better efficiency for more complex effects and higher resolutions.

Referring to the system, companies looking to deploy, or develop on, ray tracing solutions will be able to confidently understand the market and find the right technology to meet their needs. The Ray Tracing Levels system consists of six levels, with the capabilities and requirements described as follows:

  • Level 0: Legacy solutions
  • Level 1: Software on traditional GPUs
  • Level 2: Ray/box and ray/tri-testers in hardware
  • Level 3: Bounding Volume Hierarchy (BVH) processing in hardware
  • Level 4: BVH processing and coherency sorting in hardware
  • Level 5: Coherent BVH processing with Scene Hierarchy Generation (SHG) in hardware

A BVH Builder with SHG can also be added to lower efficiency levels where this would be indicated by the addition of “plus”, for example, “level 2 plus” solution.

Jon Peddie, principle, Jon Peddie Research, said, “The Ray Tracing Levels system is exactly what is needed to understand and reap the benefits of ray tracing across a range of products. Ray tracing has long been considered the utopia of 3D graphics, but the proliferation of solutions makes it far from clear whether people are even referring to the same thing when they say, ‘ray tracing’. With this system, game engines, smartphone manufacturers and more have the insight to understand the differences between ray tracing implementations, speak with specificity about ray tracing, and, ultimately, enable consumers to enjoy incredibly realistic images on mobile devices, just like they do at the cinema.”

Kristof Beets, senior director of technical product management at Imagination Technologies, added, “Real-time ray tracing is the most exciting development in 3D graphics of the last 10 years. It’s a technology that everyone wants but not everyone understands, especially when it comes to the benefits on mobile. We want to change that. By creating the Ray Tracing Levels system, we’re helping to bring clarity to the industry about the confusing range of different ray tracing offerings.”

The key point that as one moves up each level, there is an increased focus on efficiency. As Imagination noted in a blog:

“The market however does not always move based on efficiency. For example, the recently released second-generation ray tracing-capable desktop PC hardware has increased performance by simply providing more ray tracing processing – which naturally requires more silicon area and more power. However, this brute force approach is not a viable option for solutions that need to operate within a power budget, such as mobile. Ray tracing is a rendering technique that accurately traces the path of light in a scene and can render believable reflection, refraction, and lighting effects with much higher degrees of realism and fidelity than traditional rasterization techniques.”

The company said gaining an understanding of ray tracing architecture is essential to put marketing performance metrics for ray tracing into context. For example, claims for GigaRays per second may initially impress but could pale in reality if there is low efficiency linked to low utilization of GPU processing resources, or due to memory access limitations as a result of the non-coherent memory access patterns.

Imagination’s Beets told embedded.com, “The market will have to adopt some aspects of this Ray Tracing Levels system, either through this naming or some other variation.” The company hopes that once ray tracing levels are understood, then SoC designers can enable their ray tracing implementations can move from low efficiency, high-power consumption hardware into area and power-efficient devices. This in turn would benefit mobile gamers looking for lifelike, photorealistic games and high levels of immersion.

The multicore lexicon: Defining the terminology

2020-09-22 19:24 Embedded.com Colin Walls

Multicore embedded designs are becoming increasingly common. Faced with this technology for the first time, a developer is bombarded with terminology. Understanding the alphabet soup that describes this technology is essential to ensure that an optimal design is achieved. This article systematically defines many of the key terms and puts them into context.

Multicore terminology

Here are some, at least, of the key terms that are used in multicore discussion:

  • Core
  • Multicore system
  • Homogeneous multicore
  • Heterogeneous multicore
  • Bare metal
  • Asymmetric Multiprocessing (AMP)
  • Symmetric Multiprocessing (SMP)
  • Inter-core communication
  • Boot order
  • Life cycle management
  • Device virtualization
  • Hypervisor
  • Multicore framework
  • VirtIO
  • rpmsg
  • OpenAMP
  • Mixed criticality

There are probably more terms, but a working understanding of these would be a great start for a developer new to the field. The rest of this article is a series of definitions of these terms and how they link together.

Core

A processor of some kind – something that can execute code – on a system-on-chip (SoC) device. This may be a conventional CPU, or it could be a specialized processor like a Graphics Processor Unit (GPU) or Digital Signal Processor (DSP). A Microcontroller Unit (MCU) is a possibility, where the CPU has its own localized memory and peripherals. On an FPGA a soft core may be employed.

Multicore system

An embedded system that has multiple processor cores. This might be multiple boards in a system, or multiple chips on a board, but most commonly this term is used to describe a chip containing multiple processors. This may be system-on-chip (SoC) device or it could be an FPGA on which multiple soft cores are instantiated (or the FPGA may have some “hard” cores embedded within the fabric).

Homogeneous multicore

This is a hardware architecture. A multicore system where all the cores are identical. It is possible that this term may be used where the cores are all from the same family and are almost identical. This may be applicable to customizable cores like RISC-V.

Heterogeneous multicore

This is a hardware architecture. A multicore system where the cores are not all identical. The cores may be slightly different from one another or radically so. There may be a mix of regular CPUs, DSPs and/or GPUs or other specialized devices. Within the mix of cores there may be several that are identical; this can be thought of as a homogeneous multicore within the heterogeneous environment and this has implications on the software architecture.

Heterogeneous multicore is the most common hardware architecture employed in embedded applications.

Bare metal

A term that describes a core in a multicore system that is not utilizing an operating system.

Asymmetric Multiprocessing (AMP)

This is a software architecture. Each core runs its own operating system or maybe no OS at all (this is termed bare metal). The OSes may be selected so that each one is optimal for the required functionality of the core. Additional software components are needed to facilitate overall control of the device and inter-core communications; this may be a hypervisor or a multicore framework.

AMP is the most common software architecture employed in embedded applications.

Symmetric Multiprocessing (SMP)

This is a software architecture. A single instance of an operating system (which needs to be a specific variant with SMP support) runs across multiple cores. The OS manages distribution of work between the cores. The application code need not be specially written for the SMP context. The main reason for utilizing this architecture is to maximize computing power while minimizing energy use. A group of cores may constitute an SMP subsystem within an AMP design.

Inter-core communication

In a multithreaded system, tasks commonly need to communicate to exchange data or synchronization; in a multicore environment this communication may be between cores. With an AMP system, some specific support for communication is needed – typically utilizing rpmsg. This capability is generally accommodated using a hypervisor or a multicore framework. With an SMP system, the operating system facilitates communication between tasks using regular service calls.

Boot order

An AMP system, with any level of non-trivial complexity, is very likely to need some control over the sequence of cores booting. Normally, one core would be the master of the system. This capability is generally accommodated using a hypervisor or a multicore framework.

Life cycle management

The control of an AMP system may go beyond boot order and encompass the entire operation of the non-master cores. Their operation may be monitored, and they may be shut down or rebooted, as required.

Device virtualization

A facility provided by a hypervisor that enables the application software to use a device which is actually shared between multiple cores, without the code being modified to accommodate the sharing.

Hypervisor

A software component that, in a multicore system, runs across multiple cores and provides control and inter-core communication services. A hypervisor can only run across identical cores – i.e. it must be a homogeneous multicore device. The cores must also be running an operating system of some kind.

Multicore framework

An alternative software component to a hypervisor that provides similar capabilities but is lighter weight. A multicore framework has an instance on each core, so they do not need to be of the same architecture – i.e. it can be a heterogeneous multicore device. An underlying operating system is also not essential – i.e. a multicore framework may run on bare metal.

VirtIO

This is an implementation of device virtualization that is normally applied to networking and storage.

rpmsg

Remote Processor Messaging is a bus/API that facilitates communication between cores.

OpenAMP

An open standard that guides the implementation of a multicore framework. See: https://www.openampproject.org

Mixed criticality

A system where some components have safety/security implications and require certification. In various industries, devices that present safety or security issues must comply with specific standards and get that compliance certified. This is an expensive process. By partitioning a design into critical and non-critical subsystems, the costs may be reduced by only certifying the critical subsystem. Such a design is said to exhibit mixed criticality.
