standard instructions and addressing modes. The MOVEP instruction allows
host-to-memory and memory-to-host data transfers with no intermediate register.

Programming Model—DSP Viewpoint
The HI has two programming models: one for the DSP programmer and one for the
host processor programmer. In most cases, the notation used reflects the DSP
perspective. The host-to-HI programming model is shown in
Figure 4-8
. There are
three registers: the HI Control Register (HCR), the HI Status Register (HSR), and a HI
data Transmit/Receive register (HOTX/HORX). These registers can only be accessed
by the DSP56012; they can not be accessed by the host processor. The HI-to-host
processor programming model is presented in
Section
4.4.5 HI—Host Processor
Viewpoint
and is illustrated in
Figure 4-10
on page 4-23.
