C674x DSP CPU Description

The C674x Central Processing Unit (CPU) consists of eight functional units, two register files, and two
data paths as shown in

Figure 3-2

. The two general-purpose register files (A and B) each contain 32 32-

bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data
address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-
bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in
register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 MSBs in the
next upper register (which is always an odd-numbered register).

The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one
instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units
perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from
memory to the register file and store results from the register file into memory.

The C674x CPU combines the performance of the C64x+ core with the floating-point capabilities of the
C67x+ core.
