Citra Git (2015/03/03) is compiled. This is the trunk of Citra Project. Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. At this time, it only emulates a very small subset of 3DS hardware, and therefore is only useful for booting/debugging very simple homebrew demos. Citra is licensed under the GPLv2. Refer to the license.txt file included.
Citra Git Changelog:

ReplyDeleteThe 3D processing core of PICA200 consists of up to four programmable vertex pipelines that can be rearranged as four pixel pipelines. The number of IPCs and pipelines will depend on the target processor core and may change in the future.
PICA200 has an instruction-programmable core (IPC) that gives it capability to change configuration based on demands for specific target system, which will manage with its 3D graphics engine. PICA200 supports second-generation DMPs proprietary MAESTRO graphics technology ("MAESTRO-2G") which includes OpenGL ES 1.1 API support, optional OpenGL ES 1.1 extensions pack and some DMP proprietary extensions which enable custom hardware-based shading algorithms such as procedural texturing, bidirectional reflectance distribution function (BRDF), Cook-Torrance specular highlights, polygon subdivision ("Geo Shader", aka. tessellation), soft shadow projection and per-vertex subsurface scattering (similar to two-sided lighting).
PICA200 and MAESTRO-2G is a further refinement of DMP's first-generation MAESTRO developed in DMP's proof-of-concept processor ULTRAY2000.
ULTRAY2000 is concept chip for 3D graphics processing designed by Digital Media Professionals Inc. (DMP), a Japanese GPU design company, which enables the best quality real-time 3D graphics available. It was produced in 0.13 µm TSMC manufacturing process and contained more than 100 million CMOS transistors, with GPU core clock running at 200 MHz and its integrated memory controller having support for DDR-400 memory. DMP announced ULTRAY2000 concept chip July 21, 2005 and its first exhibition was at SIGGRAPH 2005. First sample shipments were scheduled for fall of 2005.
ULTRAY2000 adopted design where fixed graphics pipeline architecture coexist with advanced instruction programmable core.
ReplyDeleteULTRAY2000 features proprietary modeled algorithms for generating physical light reflection and shadow properties for various materials which are embedded on the visual processor chip as hardware specific feature (“MAESTRO” technology). This features gave chip ability for processing real-life looking 3D graphics at high-resolution in real time.
SIGGRAPH 2005's public exhibition card:
Core clock 200 MHz produced in 130 nm TSMC process [3]
256MB DDR-400 SDRAM on 256-bit memory bus[3]
- 12.8GB/s memory bandwidth
PCI interface bus supporting both 64-bit/66 MHz and 32-bit/33 MHz cards[3]
display outputs support with digital DVI-I and RGB analog Dsub-15 8DE-15/HD-15) connectors[3]
- only one display could be connected to output
support for OpenGL 2.0, OpenGL ES 2.0 and Java Mobile 3D Graphics for J2ME (JSR-000184) APIs[3]
- Mobile 3D Graphics for J2ME is more widely known as M3G 1.0/1.1 since 2007
“MAESTRO” Technology[edit]
“MAESTRO” is sophisticated technology developed by modeling various computer graphics algorithms for later hardware implementation on proprietary solutions, so that can be built on silicon as advanced graphics solutions based on customer demands.[4][5]
“MAESTRO” technology features:
Shading Maestro (previously known as Material Maestro)
- bidirectional reflectance distribution function (BRDF), subsurface scattering (SSS), which enable fast eye-candy rendering with various combination of light reflection modeling to run at a higher resolution[4][5][6]
Figure Maestro
- figure processing technology that executes within the primitive processing, it includes geometry processing (Geometry Shader --"Geo Shader") and generating polygon subdivision (aka.tessellation)[4][5][6]
Shadow Maestro
- shadow rendering enhancement which combine innovative shadow map generation method and shadow filtering process in generating shadow that applies to the final display space, and thus enable creation of beautiful partial soft-edged shadows and self shadows.[4][5][6]
Particle Maestro
- providing support for high-quality rendering of fuzzy objects which needs specific particle projection, quickly drawing gaseous form objects and beautifully renders clouds, smoke, gas and other fuzzy objects[4][5][6]
Glare Maestro
- hardware support for rendering lens flare and glare textures[4][6]
“MAESTRO-2G” Technology[edit]
“MAESTRO-2G” technology is further refinement on previous “MAESTRO” generation focused on ability to render images at even higher resolutions by reducing processing contents size and memory bandwidth usage, and thus contributing to reducing energy consumption at the system level.[5]
“MAESTRO-2G” technology additionally features:
Mapping Maestro
- rendering algorithms for embedded graphics systems based on the texture mapping (specifically bump mapping, cube mapping, multitexturing etc.) and procedural texturing reduce contents size and memory bandwidth requirements an by that improves overall application performance and removes any notion about previously supported Glare Maestro feature.
