It compresses 64-K speech to 40-, 32-, 24-, or 16-K BPS using adaptive differential pulse-code modulation (ADPCM). Mean Opinion Scores (MOS) for G.726 at the 32K rate are considered to be toll quality; the 24K rate is near toll quality. G.726 is used in applications where high-quality, low DSP MIPS, and low algorithmic delay are desired.<\/p>\n<p>Commetrex offers G.726 in a C-coded reference design, as well as versions optimized for the Texas Instruments TMS320C6000 and TMS320C5400. Commetrex\u2019 implementations are extremely resource-frugal. The \u2018C6000 version requires only 1.55 mega-cycles per second in the dual-channel version where two samples are processed simultaneously. On the 200-MHz TI \u2018C6201, this yields 120 channels per DSP. When the execution is optimized for single-channel operation the \u2018C6000 version requires 2.77-MCPS, or over 60 channels per DSP.<\/p>\n<p>G.726 is eXpress DSP Compliant (http:\/\/dspvillage.ti.com\/docs\/express_dsp\/expressdsphome.jhtml). The TMS320DSP Algorithm Standard is directly supported by the MSP Consortium M.100 specification (http:\/\/www.msp.org) so it is compatible with any MSP-conforming media-processing system.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=&#8221;&#8221; row_type=&#8221;row&#8221; use_row_as_full_screen_section=&#8221;no&#8221; type=&#8221;grid&#8221; angled_section=&#8221;no&#8221; text_align=&#8221;left&#8221; background_image_as_pattern=&#8221;without_pattern&#8221; z_index=&#8221;&#8221; css=&#8221;.vc_custom_1578318800266{padding-top: 60px !important;padding-bottom: 60px !important;background-color: #f0f0f0 !important;}&#8221;][vc_column width=&#8221;1\/2&#8243; el_class=&#8221;white-box&#8221;][vc_column_text]<\/p>\n<h2>Features<\/h2>\n<ul>\n<li>Ultra-low resource utilization<\/li>\n<li>C-callable interface<\/li>\n<li>Does not disable interrupts<\/li>\n<li>TMS320DSP Algorithm Standard compliant<\/li>\n<li>MSP Consortium M.100 compatible<\/li>\n<li>Industry\u2019s lowest MIPS utilization<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243; el_class=&#8221;white-box&#8221;][vc_column_text]<\/p>\n<h2>Benefits<\/h2>\n<ul>\n<li>High densities<\/li>\n<li>Low power<\/li>\n<li>Low implementation cost<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=&#8221;&#8221; row_type=&#8221;row&#8221; use_row_as_full_screen_section=&#8221;no&#8221; type=&#8221;grid&#8221; angled_section=&#8221;no&#8221; text_align=&#8221;left&#8221; background_image_as_pattern=&#8221;without_pattern&#8221; z_index=&#8221;&#8221; css=&#8221;.vc_custom_1578569345116{padding-bottom: 60px !important;background-color: #f0f0f0 !important;}&#8221;][vc_column width=&#8221;1\/2&#8243; el_class=&#8221;white-box&#8221;][vc_column_text]<\/p>\n<h2>\u2018C6000 Resource Utilization<\/h2>\n<p>MCPS dual-sample encode: 1.54<br \/>\nMCPS dual-sample decode: 1.64 (32K rate)<br \/>\nProgram Memory (full duplex): 9K bytes<br \/>\nPer-Instance Memory: 54 bytes[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243; el_class=&#8221;white-box&#8221;][vc_column_text]<\/p>\n<h2>License Options<\/h2>\n<p>Limited-Use Paid-Up Source Code<br \/>\nRoyalty with Reduced Up-Front<br \/>\nObject Code with Runtime Licenses<\/p>\n<h2>Ordering Information<\/h2>\n<p>G.726 on \u2018C5400 \u2013 PN 60092-1<br \/>\nG.726 on \u2018C6000 \u2013 PN 60092-2[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row css_animation=&#8221;&#8221; row_type=&#8221;row&#8221; use_row_as_full_screen_section=&#8221;no&#8221; type=&#8221;grid&#8221; angled_section=&#8221;no&#8221; text_align=&#8221;left&#8221; background_image_as_pattern=&#8221;without_pattern&#8221; z_index=&#8221;&#8221; css=&#8221;.vc_custom_1578318404627{padding-top: 60px !important;padding-bottom: 0px !important;background-color: #f0f0f0 !important;}&#8221;][vc_column][vc_column_text]ITU G.726 is the most&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":98,"menu_order":161,"comment_status":"closed","ping_status":"open","template":"template-products.php","meta":{"footnotes":""},"class_list":["post-1375","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/pages\/1375","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/commetrex.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1375"}],"version-history":[{"count":2,"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/pages\/1375\/revisions"}],"predecessor-version":[{"id":5215,"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/pages\/1375\/revisions\/5215"}],"up":[{"embeddable":true,"href":"https:\/\/commetrex.com\/index.php?rest_route=\/wp\/v2\/pages\/98"}],"wp:attachment":[{"href":"https:\/\/commetrex.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1375"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
