Briey Introduction
Briey is the name of a little FPGA SoC fully written in SpinalHDL. Goals of this project are multiple :
Prove that SpinalHDL is a viable HDL alternative in non-trivial projects.
Show advantage of SpinalHDL meta-hardware description capabilities in a concrete project.
Provide a fully open source SoC.
Pinsec has followings hardware features:
AXI4 interconnect for high speed busses
APB3 interconnect for peripherals
RISCV CPU with instruction cache, MUL/DIV extension and interrupt controller
JTAG bridge to load binaries and debug the CPU
SDRAM SDR controller
On chip ram
One UART controller
One VGA controller
Some timer module
Some GPIO
The toplevel code explanation could be find there
Board support
A DE1-SOC FPGA project can be find there with some demo binaries.
