Digital Signal Processors (DSP)
Single-precision unsigned-integer format
Semiconductors; Digital Signal Processors (DSP)
A 32-bit unsigned format for integer data.
Interprocessor command
Semiconductors; Digital Signal Processors (DSP)
A message sent through the crossbar to the other on-chip processors.
Internal address
Semiconductors; Digital Signal Processors (DSP)
An address internal to the multimedia video processor (MVP) chip. Addresses from 0x0000 0000 to 0x1FFF FFFF are on-chip addresses. Also called on-chip address.
SNaN
Semiconductors; Digital Signal Processors (DSP)
Signalling not-a-number. A floating-point number that has no numerical value but is used to signal the master processor in certain exception conditions.
Output data-scaling shifter
Semiconductors; Digital Signal Processors (DSP)
A 32- to 16-bit barrel left shifter. Shifts the 32-bit accumulator output from 0 to 7 bits left for quantization management, and outputs either the 16-bit high or low half of the shifted 32-bit data ...
Global memory allocation register (GREG)
Semiconductors; Digital Signal Processors (DSP)
A memory-mapped register used for specifying the size of the global data memory. Addresses not allocated by the GREG for global data memory are available for local data memory.
Host port interface (HPI)
Semiconductors; Digital Signal Processors (DSP)
An 8-bit parallel interface that the CPU uses to communicate with a host processor.
