#技术资源# GD32F450,区分 Data area,Code area ,从搜索资料来看, 都说Data area都是慢速的。
我查看官方资料,有这样描述:
Up to 3072KB of on-chip flash memory for instruction and data.
The region of the MCU executing instructions without waiting time is up to 1024K bytes
(in case that flash size equal to 256K or 512K, all memory is no waiting time). A long
delay when CPU fetches the instructions out of the range.
这是不是说明 1024K bytes 是零等待区域? 对于GD32F450,Code area最多是512KB ,那么前面512KB Data area 也是高速的? |
