MOSFET Automatic Power Switching

A N-channel power MOSFET ik IRFZ44N has a body diode running from Source to Drain.

For acting like a switching, Gate voltage should be positively greater than VgsV_{gs}

Introduction to Tonemapping

Tonemapping

Schlick (1994)

Photorealistic rendering techniques, chapter Quantization Techniques for the Visusalization of High Dynamic Range Pictures

  • Sigmoid compression

Schlick’s s-shaped curve reduces some of the problems caused by clipping however its limited dynamic range makes it only viable for MDR images.

Tumblin (1999)

Two methods for display of high contrast images.

  • tanh

Durand (2004)

  • bilateral filter

detailed layer (LDR) + base layer (HDR) or, illuminance and reflectance layer

About Vulkan and Future of High Performance Computing

Towards a heterogeneous & parallel computing architecture

OpenCL and Vulkan in the future would probably become the same thing. [1][2]

To utilise the power of Vulkan (and OpenCL) we do not have to code it our own, espectially for the purpose of deep learning.

By the way, some framework utilise OpenGL (Compute Shader API) as well, a higher level API.

Mali-G series GPU supports OpenCL 2.0 full profile.
