How can microcode offer such significant performance gain?
By operating On-The-Fly, hence eliminating the need for costly load/store operations. Every payload bit in the packet/frame/character is seen by the CPM on its way to/from a FIFO from/to am application memory. As such the CPM can handle much of what used to be an application task while the bit stream stored temporarily in the DPRAM. This saves considerable amount of cycle by eliminating the need for a load/store operation. In addition, the microcode program must be, by definition, extremely efficient, due to low-level programming, and the relatively limited on-chip ROM/RAM capacity. 3. DoGav Systems’ Microcode Customisation Service 3.1 How easy is it to install a customized microcode? Very easy. Together with the microcode DoGav Systems also provides a c-language file which contains a function that carries out the installation process automatically. All the user has to do is call that function before enabling the specific serial controller. The installation process only lasts several m
