    Abstract: A DSP coprocessor 2 is connected to a host sub-system (3). The host sub-system (3) has a host processor (4), a host RAM (5), and shared RAM banks (6, 7). Multiplexers (11) provide access for either the DSP or the host to a shared RAM bank. Macro commands for functions of the DSP coprocessor are retrieved from the shared RAM banks. This allows comprehensive interaction of the host and the DSP coprocessor.
