WebMar 8, 2011 · This has the important consequence that you do not need to write your own GPU shader/kernel code for H.264 decoding (e.g. via CUDA or OpenCL), since the "programmable" part of the GPU is not even used. Instead, you just use the "hardwired" H.264 decoding routines that already are burnt into the silicon. WebSemáforo FreeRTOS. Las funciones de la API de semáforo son en realidad macros, que utilizan el mecanismo de cola existente. Estas macros se definen en el archivo semphr.h. Si usa semáforos o mutex, debe incluir el archivo de encabezado semphr.h. Los semáforos incluyen semáforos binarios, semáforos contadores, semáforos mutuamente ...
