| | Operating systems do great work, but sometimes they need a little bit of help to know when to switch from one task to another. Thankfully, hardware is there to help! Today we are going to take a look at how operating systems schedule reminders for themselves using timer interrupts. Sections Link to heading Don't care about the why and just want to see the code?

| | Continuing with the implementation of CHIP-8 in Verilog, I wanted to continue with the CPU module and get it to actually execute some instructions, so we'll build an instruction decoder, CPU states and a register file. As described in the previous part , we would like to: fetch instruction (2 bytes) from the memory into an 16-bit opcode register decode the instruction execute the instruction Other articles in the series:
