Abstract: front page image
(EN)An interface includes a slave digital signal processor (DSP) and a master DSP connected to the slave DSP through a communications port. The master DSP includes a memory; and a direct memory access (DMA) to the memory. A field programmable gate array (FPGA) is connected to the master DSP. The FPGA includes a dual port random access memory (RAM) in communication with the DMA. A universal serial bus (USB) interface is connected to the FPGA through the dual port RAM.
(FR)Une interface comprend un processeur de signal numérique (DSP) esclave et un DSP maître connecté au DSP esclave par un port de communications. Le DSP maître comprend une mémoire ainsi qu'un accès mémoire direct (DMA) à la mémoire. Un prédiffusé programmable (FPGA) est connecté au DSP maître. Le FPGA comprend une mémoire vive (RAM) à deux ports en communication avec le DMA. Une interface de bus série universel (USB) est connectée au FPGA par la RAM à deux ports.
