WebJan 12, 2024 · u8 = uint8 (u16/256) % scale and convert to 8bits. u8_2 = im2uint8 (u16) % compare to built in fcn. However, I get some discrepancies between the two conversions. For uint16 value of 128, the im2uint8 function gives zero, while the uint8 command gives 1. To my understanding it should be 1, but since Matlab gives it as 0, it made me confused.

Unaligned memory accesses occur when you try to read N bytes of data starting from an address that is not evenly divisible by N (i.e. addr % N != 0). For example, reading 4 bytes of data from address 0x10004 is fine, but reading 4 bytes of data from address 0x10005 would be an unaligned memory access. thurso dental centre

Convertion from U16 in U8 results overflow. Why?

Web@Fluffy It's not faster if all fields are the same size. The logic is that u8 is 8-bit aligned while u16 is16-bit aligned. This creates a necessary 8-bit space between the two. You can choose to use the space yourself (by extending the first field to 16 bits or by introducing an intermediate 8-bit field) or you can leave it unused (and it's called padding) but either way … WebHello all, I made the following example: typedef unsigned int U16; typedef unsigned char U8; // case 1; U16 a = 0x0FFF; U16 b = 0x0E00; U8 c = 0x00; ... thurso delivery officeWebAug 23, 2024 · Since you’re working to an external specification, you probably want to mark those structs #[repr(C)] so that they have a stable layout.
