GonTa Calculator is a new mobile computing platform. Currently it's virtualized, we have an emulator to test everything, but in the future we may test it in real hardware (using a fpga perhaps).
The platform itself was originally designed for a calculator with a lot of features, but it can also be used for domotics (using some GPIO to interface the real world) or to retro gaming.
16 Bit microprocessor with 16 bit address bus (it can address up to a total of 64KiB of linear memory, unless we use the flash memory as ram) 320x240 pixel black&white screen (has a framebuffer of 9600 bytes) Resistive touchscreen capable of tracking one point Sound controller capable of mixing up to 4 sounds. Vibrating motor for tactile feedback in games. UART to communicate with other devices (RS232-SPI-I2C) Flash memory of up to 4GB (32 Bit address bus) Built-in ROM and bootloader capable of loading a program from flash or serial.
The project itself is divided into four sections:
Documentation (Specs, CPU opcodes, etc) Emulator (WIP, done in c++, using SDL for graphics and audio) Assembler (WIP, capable of assembling a asm file) Disassembler (WIP, capable of translating an object file to its mnemonics)
