description
The SMJ320C50 digital signal processor (DSP) is a high-performance, 16-bit, fixed-point processor
manufactured in 0.72-
m double-level metal CMOS technology. The SMJ320C50 is the first DSP from TI
designed as a fully static device. Full-static CMOS design contributes to low power consumption while
maintaining high performance, making it ideal for applications such as battery-operated communications
systems, satellite systems, and advanced control algorithms.
A number of enhancements to the basic SMJ320C2x architecture give the ’C50 a minimum 2
× performance over
the previous generation. A four-deep instruction pipeline, incorporating delayed branching, delayed call to
subroutine, and delayed return from subroutine, allows the ’C50 to perform instructions in fewer cycles. The
addition of a parallel logic unit (PLU) gives the ’C50 a method for manipulating bits in data memory without using
the accumulator and ALU. The ’C50 has additional shifting and scaling capability for proper alignment of
multiplicands or storage of values to data memory.
The ’C50 achieves its low-power consumption through the IDLE2 instruction. IDLE2 removes the functional
clock from the internal hardware of the ’C50, which puts it into a total-sleep mode that uses only 7
A. A low-logic
level on an external interrupt with a duration of at least five clock cycles ends the IDLE2 mode.
The ’C50 is available with two clock speeds. The clock frequencies are 50 MHz, providing a 40-ns cycle time,
and 66 MHz, providing a 30-ns cycle time. The available options are listed in the following table.
