3D game running on FPGA shown to be 50x more efficient than on x86 hardware

Sphery vs. shapes is an open-source 3D raytraced game written in C and translated into FPGA bitstream that runs 50 times more efficiently on FPGA hardware than on an AMD Ryzen processor. Verilog and VHDL languages typically used on FPGA are not well-suited to game development or other complex applications, so instead, Victor Suarez Rovere and Julian Kemmerer relied on Julian’s “PipelineC” C-like hardware description language (HDL) and Victor’s CflexHDL tool that include parser/generator and math types library in order to run the same code on PC with a standard compile, and on FPGA through a custom C to VHDL translator. More details about the game development and results are provided in a white paper. Some math functions were needed, including: floating point addition, subtraction, multiplication, division, reciprocals, square root, inverse square roots, vector dot products, vector normalization, etc. Fixed point counterparts were also used for performance reasons and to […]

ChipWhisperer-Husky is a palm-sized power analysis and fault injection tool (Crowdfunding)

power analysis fault injection tool STM32F Target Board

NewAE Technology’s ChipWhisperer-Husky is a compact tool designed for side-channel power analysis and fault injection with features such as a high-speed logic analyzer used to visualize glitches, real-time data streaming for attacking asymmetric algorithms, and support for JTAG/SWD programming. The security research company explains its device delivers a more stable and reliable experience compared to other off-the-shelf test gear such as oscilloscopes and function generators thanks to features such as synchronous sampling, which means the sample clock of your target device and the sample clock of ChipWhisperer-Husky can be perfectly aligned, or the ability to generate glitches, including clock glitches that can be less than a nanosecond wide. ChipWhisperer-Husky key features and hardware specifications: Synchronous clock for capture board and target board for significantly improved performance over a typical asynchronous oscilloscope setup 12-bit 200MS/s ADC for capturing power traces – It can be clocked at both the same clock […]

Ztachip open-source RISC-V AI accelerator performs up to 50 times faster

Ztachip is an open-source RISC-V accelerator for vision and AI edge applications running on low-end FPGA devices or custom ASIC that is said to perform 20 to 50 times faster than on non-accelerated RISC-V implementations, and is also better than RISC-V cores with vector extensions (no numbers were provided here). Ztachip, pronounced zeta-chip, is not tied to a particular architecture, but the example code features a RISC-V core based on the VexRiscv implementation and can accelerate common computer vision tasks such as edge detection, optical flow, motion detection, color conversion, as well as TensorFlow AI models without retraining. The open-source AI accelerator has been tested on Digilent ArtyA7-100T FPGA board in combination with a PMOD VGA module to connect to a display and an OV7670 VGA camera module. You can then build the sample found on Github with the Xilinx Vivado Webpack free edition and flash it to the board […]

India goes RISC-V with VEGA processors

One of the main advantages of RISC-V architecture is that it is open, so any organization with the right skills can develop its own cores, and India’s government has taken up this opportunity with the Microprocessor Development Programme (MDP) helping develop VEGA RISC-V cores locally. Thanks to funding by the Ministry of Electronics and Information Technology (MeitY), the Centre for Development of Advanced Computing (C-DAC) managed to design five RISC-V processors ranging from a single-core 32-bit RISC-V microcontroller-class processor to a Linux capable quad-core 64-bit out-of-order processor. Key features of the five VEGA cores developed by the C-DAC: VEGA ET1031 – 32-bit single-core 3-stage in-order RV32IM processor with AHB/AXI4.bus, optional MMU, optional Debug VEGA AS1061 – 64-bit single-core 6-stage in-order RV64IMAFDC processor with 8KB D-cache, 8KB I-cache, FPU, AHB/AXI4 bus VEGA AS1161 – 64-bit single-core 16-stage pipeline out-of-order RV64IMAFDC processor with 32KB D-cache, 32KB I-cache, FPU, AHB/AXI4/ACE bus VEGA AS2161 […]

FPGA Meets Breadboard with Mercury 2 Xilinx Artix-7 FPGA Development Board

FPGA Meets Breadboard - Mercury-2 Development Board

While we now come across more and more FPGA development boards, very few are designed to be inserted into a breadboard. We’ve previously covered TinyFPGA BX, Fipsy, and QuickFeather FPGA breadboard-friendly boards. All those boards are however based on entry-level FPGAs like Lattice Semi ICE40 or QuickLogic EOS S3, and if you’d like a more powerful FPGA board that fits into a breadboard, MicroNova Mercury 2 development board may meet your requirements with a Xilinx Artix-7 FPGA. MicroNova Mercury 2 specifications: FPGA – Xilinx Artix-7A FPGA (XC7A35T) with 33,280 logic cells or XC7A100T with 101,440 logic cells System Memory – 4 Mbit (512K x 8-bit) asynchronous SRAM Storage – 32 Mbit SPI flash for configuration & user data Networking – On-board Microchip LAN8720A 10/100M Ethernet PHY USB – Dual-channel high-speed USB 2.0 micro USB port (ch A for config, ch B for user) 2x 32-pin headers Fast Ethernet signals 8-channel, […]
