\u00cembun\u0103t\u0103\u021bim exemplul generatorului tonal<\/h2>\n

<\/p>\n

\u00cen articolul anterior pe care l-a\u021bi citit<\/a><\/noindex> Am scris o aplica\u021bie pentru generatorul tonal \u0219i cu ajutorul acesteia am extras sunetul din difuzorul computerului. Acum ne vom concentra pe faptul c\u0103 programul nostru, la finalizarea lucr\u0103rii, nu returneaz\u0103 memoria \u00eenapoi \u00een heap. A sosit timpul s\u0103 clarific\u0103m aceast\u0103 problem\u0103.<\/p>\n

<\/a><\/noindex><\/p>\n

Dup\u0103 ce schema nu ne mai este necesar\u0103, eliberarea memoriei trebuie s\u0103 \u00eenceap\u0103 prin oprirea conveierului de date. Pentru aceasta, trebuie s\u0103 deconect\u0103m sursa ceasului de la schem\u0103, ticker-ul, folosind func\u021bia ms_ticker_detach()<\/em>. \u00cen cazul nostru, trebuie s\u0103 deconect\u0103m ticker-ul de intrarea filtrului voidsource<\/em>:<\/p>\n

<\/p>\n

ms_ticker_detach(ticker, voidsource)<\/code><\/pre>\n
<\/p>\n
Apropo, dup\u0103 oprirea conveierului, putem schimba schema \u0219i s\u0103 o repornim, reconect\u00e2nd ticker-ul.<\/p>\n
<\/p>\n
Acum putem s\u0103-l elimin\u0103m, folosind func\u021bia ms_ticker_destroy()<\/em>:<\/p>\n
<\/p>\n
ms_ticker_destroy(ticker)<\/code><\/pre>\n
<\/p>\n
Conveierul este oprit \u0219i putem s\u0103 \u00eencepem dezasamblarea acestuia, deconect\u00e2nd filtrele. Pentru aceasta, se folose\u0219te func\u021bia ms_filter_unlink()<\/em>:<\/p>\n
<\/p>\n
ms_filter_unlink(voidsource, 0, dtmfgen, 0);\nms_filter_unlink(dtmfgen, 0, snd_card_write, 0);<\/code><\/pre>\n
<\/p>\n
Destina\u021bia argumentelor este aceea\u0219i ca la func\u021bia ms_filter_link()<\/em>.<\/p>\n
<\/p>\n
Elimin\u0103m acum filtrele deja deconectate cu ajutorul ms_filter_destroy()<\/em>:<\/p>\n
<\/p>\n
ms_filter_destroy(voidsource);\nms_filter_destroy(dtmfgen);\nms_filter_destroy(snd_card_write);<\/code><\/pre>\n
<\/p>\n
Ad\u0103ug\u00e2nd aceste linii \u00een exemplul nostru, vom ob\u021bine o terminare corect\u0103, din punct de vedere al gestion\u0103rii memoriei, a programului.<\/p>\n
<\/p>\n
Dup\u0103 cum vedem, terminarea corect\u0103 a programului a necesitat s\u0103 ad\u0103ug\u0103m aproximativ la fel de multe linii de cod ca la \u00eenceput, iar \u00een medie, pentru fiecare filtru, au fost necesare patru linii de cod. Rezultatul este c\u0103 dimensiunea codului programului va cre\u0219te propor\u021bional cu num\u0103rul de filtre utilizate \u00een proiect. Dac\u0103 vorbim despre o mie de filtre \u00een schem\u0103, atunci codului vostru i se va ad\u0103uga patru mii de linii de opera\u021biuni de rutin\u0103 pentru crearea \u0219i distrugerea lor.<\/p>\n
<\/p>\n
Acum \u0219ti\u021bi cum s\u0103 \u00eencheia\u021bi corect un program care utilizeaz\u0103 un media streamer. \u00cen exemplele urm\u0103toare, din motive de concizie, voi \"uita\" s\u0103 fac acest lucru. Dar voi nu ve\u021bi uita?<\/p>\n
<\/p>\n
Dezvoltatorii media streamer-ului nu au prev\u0103zut instrumente software pentru a facilita manipularea filtrelor la asamblarea\/dezasamblarea schemelor. Cu toate acestea, exist\u0103 un asistent care permite inserarea\/extragerea rapid\u0103 a filtrelor din schem\u0103.<\/p>\n
<\/p>\n
Ne vom \u00eentoarce la solu\u021bia acestei probleme mai t\u00e2rziu, c\u00e2nd num\u0103rul de filtre din exemplele noastre va dep\u0103\u0219i c\u00e2teva zeci.<\/p>\n
<\/p>\n
\u00cen urm\u0103toarea pe care l-a\u021bi citit<\/a><\/noindex> Vom construi schema unui m\u0103sur\u0103tor de nivel de semnal \u0219i vom \u00eenv\u0103\u021ba s\u0103 citim rezultatul m\u0103sur\u0103torii din filtru. Vom evalua precizia m\u0103sur\u0103rii.<\/p>\n
