Carvel SOC provides 38 GPIO pins for user functionality. Riscduino SOC GPIO Pin Mapping as follows vs ATMEGA328 and Arudino
Riscduino SOC Integrated Dual 32 Bits RISC V core. Initial version of Single core RISC-V core is picked from Syntacore SCR1 (https://github.com/syntacore/scr1)
Following Design changes are done on the basic version of syntacore RISC core
* Some of the sv syntex are changed to standard verilog format to make compatibile with opensource tool iverilog & yosys * local Instruction Memory depth increased from 4 to 8 location * Instruction Mem Request are changed from Single word to 4 Word Burst * Multiplication and Divsion are changed to improve timing * Additional pipe line stages added to improve the RISC timing closure near to 50Mhz * 2KB instruction cache * 2KB data cache * Additional router are added towards instruction cache * Additional router are added towards data cache * Dual core related changes * Modified AXI/AHB interface to wishbone interface for instruction and data memory interface
* RV32I or RV32E ISA base + optional RVM and RVC standard extensions * Machine privilege mode only * 2 to 5 stage pipeline * 2KB icache * 2KB dcache * Optional Integrated Programmable Interrupt Controller with 16 IRQ lines * Optional RISC-V Debug subsystem with JTAG interface * Optional on-chip Tightly-Coupled Memory
