Digital Signal Processors (DSP)
Bitmap
Semiconductors; Digital Signal Processors (DSP)
1) A digital representation of an image in which bits are mapped to pixels. 2) A block of memory used to hold raster images in a device-specific format.
Sequential mode
Semiconductors; Digital Signal Processors (DSP)
A master processor (MP) floating-point unit mode in which the MP executes a single floating-point instruction to completion before starting another floating-point instruction.
Profiling
Semiconductors; Digital Signal Processors (DSP)
A technique used to determine how long a processor spends in each section of a program.
Flash memory
Semiconductors; Digital Signal Processors (DSP)
Nonvolatile read-only memory that is electronically erasable and programmable.
External flag (XF) pin status bit
Semiconductors; Digital Signal Processors (DSP)
1) A field that drives the level of the external flag (XF) pin. At reset, XF = 1. This bit is stored in status register 1.
Cache clean
Semiconductors; Digital Signal Processors (DSP)
A master processor (MP) operation that updates external memory by writing modified (dirty) data-cache subblocks back to memory, thus resetting that subblock’s dirty bit to 0.
Vertical synchronisation (VSYNC)
Semiconductors; Digital Signal Processors (DSP)
.A bidirectional vertical timing signal occurring once per frame with a pulse width defined as an integral number of of lines (halflines for interlaced mode).
