Revision 2.00
10.3. Performance and Data Throughput
The following table gives the data transfer rates between different memory, processor
and interface resources on the Monaco board. Monaco boards using the TMS320C6201
processor have a clock speed of 200 MHz; Monaco67 boards using the TMS230C6701
processor have a clock speed of 167 MHz.
