Crate tpu_sg2002 

Minimal TPU device layer for SG2002.

Bare-metal, OS-agnostic TPU driver for the CVITEK SG2002 SoC.

Usage

use tpu_sg2002::{TpuDevice, TpuConfig, KernelFns, LogLevel, TimeStamp};
use core::ptr::NonNull;

struct MyKernelFns;
impl KernelFns for MyKernelFns {
    fn sleep_ms(&self, ms: u32) { /* ... */ }
    fn now_us(&self) -> TimeStamp { /* ... */ }
    fn log(&self, level: LogLevel, msg: &str) { /* ... */ }
}

let tdma_base = NonNull::new(0x0C00_0000 as *mut u8).unwrap();
let tiu_base = NonNull::new(0x0C01_0000 as *mut u8).unwrap();
let mut tpu = TpuDevice::new(tdma_base, tiu_base, TpuConfig::default(), MyKernelFns);
tpu.platform_init().expect("TPU init failed");
