КРАЙНЕ медленный! Даже тупая в лоб перестановка битов с помощью ~64 пар инструкций UBFX/BFI - будет в разы быстрее. Только два цикла - внутренний и внешний дадут уже 64 прохода во внутреннем цикле. А один проход внутреннего цикла - это множество тактов. Так как требует: чтения исходного слова, чтения целевого слова, модификации бита в нём, записи целевого слова. Это не считая трат на организацию самих циклов. А UBFX/BFI = это всего 2 такта. Как уже писал: bit-band в этой задаче - самый медленный способ.

(Почему то я не удивлён) Я всего лишь добиваюсь, чтобы вы сами это сделали. Чтобы не говорили потом, что это "я неправильно вас понял" или "вы совсем не это имели в виду". Чтобы сами убедились в бесперспективности своего способа. Цитата Держите: union Encoder { uint8_t b[8]; uint64_t data; }; uint64_t encode(uint64_t data) { union Encoder e; e.data = data; return t0[e.b[0]] | t1[e.b[1]] | t2[e.b[2]] | t3[e.b[3]] | t4[e.b[4]] | t5[e.b[5]] | t6[e.b[6]] | t7[e.b[7]]; } И разве здесь не очевидно, что это будет работать КРАЙНЕ медленно? Это даже если потратить так неэффективно 16КБ внутренней быстрой ОЗУ? Располагаем массивы во внутреннем быстром ОЗУ, компилим при максимальной оптимизации, выполняем (при запрещённых прерываниях) на CM4, получаем время выполнения = ~99 тактов! Это при том, что тот код, который я приводил, на ту же самую операцию тратит 85 тактов. На том же МК. Без всяких гигантских таблиц А в реальности таблицы будут во флешь, а значит время выполнения может ещё многократно увеличиться. Так в чём же смысл вашего табличного метода? Цитата Т.е. слились. Как и следовало ожидать Я не понимаю к чему все эти "слились", "корона не жмёт" о которой вы всё время талдычите? Когда обсуждается чисто технический вопрос. У вас какие-то проблемы в личном плане? Сливались до сих пор только вы. Когда отказывались предоставить рабочий код, чтобы наглядно показать вам всю бесперспективность вашего способа. И как только его предоставили - всё стало совершенно очевидно. Теперь любой может проверить сам и убедиться. PS: Ещё вопросы есть? или теперь даже до вас дошло, что ваш метод бесполезный?

И да - причём тут "своп битов" если задача состояла совсем в другом? Ваш результат - неверный. Решение - неверное. Правильное решение задачи будет? Или продолжите в том же духе пустой звон? PS: А своп битов делается 2-мя командами RBIT. Это всего 2 такта(!) (не считая загрузки/выгрузки). И не требует воротить тонну быдлокода.

Пусть в среднем 2 такта на инструкцию и увеличим число инструкций до 1800. При развертке 100 Гц получается 360к тактов, что при 72 МГц тактовой частоты дает нагрузку 0.5%. Ядро Cortex-M3. Добавьте в ваш код таблицу n_pos. Она константная, поэтому будем считать, что ничего не изменяется в плане быстродействия, но в плане сопровождения просто хочется видеть насколько это муторно. У вас код 85 тактов. Умножаем на 4 (VALUE_SIZE) получается 340, т.е. примерно в 8 раз быстрее. Кста, размер кода у меня порядка 100 байт, у вас - в три * 4 раза больше. Т.е. по размеру я выигрываю в 12 раз ;) Цитата Поделиться сообщением Ссылка на сообщение Поделиться на другие сайты Поделиться

Мой тот код - он для Cortex-M4 и не будет работать на CM3. Писал там же об этом. На CM3 придётся выполнить ~64 пары UBFX/BFI. Но всё равно это должно быть многократно быстрее bit-band. Не в 8 раз, а в 4-5 наверное. 3 минуты назад, adnega сказал: Кста, размер кода у меня порядка 100 байт, у вас - в три * 4 раза больше.

Если бы речь шла об оптимизации размера, я бы сделал всё равно не на bit-band, а в регистрах CPU. И ещё неизвестно что имело бы меньший размер. Но даже в таком виде - быстрее было бы в регистрах.

На самом деле исходные 8 байт идут не подряд, а с некоторым шагом (например, 4 байта). Походу, ваш алгоритм от этого становится менее быстрым. Кста, в некоторых случаях шаг может быть значительно больше, и даже не степень двойки (например, 32 + 4 = 36). Цитата Поделиться сообщением Ссылка на сообщение Поделиться на другие сайты Поделиться
