DSP's have often uncommon sizes. tms320c5502 for example has following sizes: char-- 16 bits short --16 bits int --16 bits long-- 32 bits long long -- 40 bits

- brandmeyer 6y agoIndeed. The C28x line by the same company shares CHAR_BIT == 16 with C55. C28x is quite popular in power electronics applications. "Relevant" is in the eyes of the beholder, and its all too easy to no-true-scotsman your way out of existing architectures. I claim that both of these architectures are relevant by virtue of suppliers continuing to make new chips that use them, and system builders continuing to select those chips in new products.
- rocqua 6y ago> 40 bits float-- 32 bits double Isn't double required to have more precision than float?
- ericbarrett 6y agoI think their formatting got swallowed by HN: char-- 16 bits short --16 bits int --16 bits long-- 32 bits long long -- 40 bits float-- 32 bits double -- 64 bits
- Asraelite 6y ago> long long -- 40 bits Isn't this in direct contradiction to what the article says? > long long: At least 64 bits, and at least as wide as long.
