First-in, first-out buffer. A portion of memory in which data is stored and then retrieved in the same order in which it was stored. The synchronous serial port has two four-word-deep FIFO buffers: one for its transmit operation and one for its receive operation.

This mode determines the behavior of the accumulator in the event of an overflow. In saturation mode, an overflow in the accumulator causes the accumulator to be loaded with a preset value. If the overflow is in the positive direction, the accumulator is loaded with its most positive number. If the overflow is in the negative direction, the accumulator is filled with its most negative number.
Industry:Semiconductors
A synchronous serial port mode in which only one frame synchronization pulse is necessary to transmit or receive several consecutive packets at maximum frequency. See also burst mode.

Memory that is not defined as part of the memory map and cannot be loaded with code or data.
Industry:Semiconductors
Memory that is specified within the MEMORY directive of a linker command file and used by the linker for allocation of program code and data.
Industry:Semiconductors
A linked, executable object file that is downloaded and executed on a target system.
Industry:Semiconductors
A local address unit operation. This is a memory access that usually occurs over the local port.
Industry:Semiconductors
A technique used by several functions (such as malloc, calloc, and realloc) to dynamically allocate memory for variables at runtime. This is accomplished by defining a large memory pool (heap) and using the functions to allocate memory from the heap.

Traditionally, a byte is a sequence of 8 adjacent bits operated upon as a unit. However, the TMS320C2x/C2xx/C5x byte is 16 bits.
By ANSI C definition, the sizeof operator yields the number of bytes required to store an object. ANSI further stipulates that when sizeof is applied to char, the result is 1. Since the TMS320C2x/C2xx/C5x char is 16 bits (to make it separately addressable), a byte is also 16 bits. This can yield unexpected results; for example, sizeof (int) = = 1 (not 2).
TMS320C2x/C2xx/C5x bytes and words are equivalent (16 bits).
A byte is 32 bits for the TMS320C3x/C4x. On a parallel processor and the ’C6x, where the smallest addressable unit is 8 bits in length, the C definition corresponds to the traditional notion of an 8-bit byte.
