Digital Signal Processors (DSP)

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.

FSX pin

Semiconductors; Digital Signal Processors (DSP)

Transmit frame synchronization pin.

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.
