| | | | | VGA on an FPGA In the previous articles Ive mainly interfaced with LCD displays. I thought it would be nice a produce a VGA output from my FPGA board. Ive already had a working framebuffer-based display controller that can be written to through a serial port, so this was a matter of developing a bitmapped VGA controller. Target resolution - 320x240 over 640x480 Why 320x240? Because my development board only 276. | |

| | | | | This is part of a series of posts detailing the steps and learning undertaken to design and implement a CPU in VHDL. Previous parts are available here, and I'd recommend they are read before continuing. I've been working towards HDMI output on my TPU SOC, and this week I managed to get enough of something to get pixels (very large pixels!) output to the screen. The plan was to map an area of memory to a VRAM block, which could be read and written to form the TPU, and also read for the graphics subsystem that would generate the video signals that are to be output. | |

| | | | | To work with standard monitors and TVs, you need to use the correct video timings. This how to includes the timings for five standard display modes using analogue VGA, DVI, HDMI, or DisplayPort: 640x480 (VGA), 800x600 (SVGA), 1280x720, and 1920x1080 (30 Hz and 60 Hz). | |

| | | CHIP-8 is one of the most popular target architectures for aspiring emulator writers. I'm planning to implement it in hardware, so I thought that writing a software emulator/interpreter would be enlightening. I was also looking for some practice before implementing CHIP-8 in hardware in Verilog :) CHIP-8 Virtual machine description: 64x32 pixel monochrome display 4K of 8-bit RAM 16 8-bit "variable" registers V0-VF I 16-bit address register Stack of 16-bit addresses for call/return 16-bit PC - program counter 8-bit delay timer (decremented at 60 Hz) until it reaches 0 8-bit sound timer (decremented at 60 Hz), beeps when it reaches 0 16- key keypad that sends scan codes 0x1-0xF Instruction set See https://en. | ||
