94 / 221 page  5.0 Memory Organization CN8478/CN8474A/CN8472A/CN8471A 5.1 Memory Architecture Multichannel Synchronous Communications Controller (MUSYCC™) 5-8 Conexant 100660E Next, the host allocates the required shared memory for transmit and receive messages. Assume, for example, the host needs 8 message descriptors for each channel and direction, and each corresponding data buffer per message is 100h (256) bytes in length. Memory for Message Descriptors = 32 channels/group * 2 directions/channel * 12 bytes/message descriptor * 8 buffers/channel = 1800h bytes/group = 6144 bytes/group Memory for Data Buffers = 32 channels/group * 2 directions/channel * 8 buffers/channel * 256 bytes/buffer = 131, 072 bytes/group = 20,000h bytes/group Further, the host may choose to allocate all the memory contiguously, or it may allocate the memory for message descriptors separately from data buffers. In this case, message descriptors for 8 Channel Groups may be merged into a contiguous block of memory [(1800h x 8 = C000h) bytes in length]. |
