description
With a 100-ns instruction cycle time and an
innovative
memory
configuration,
the
SMJ320C26 performs operations necessary for
many real time digital signal processing algo-
rithms. Since most instructions require only one
cycle, the SMJ320C26 is capable of executing ten
million instructions per second. On-chip program-
mable data/program RAM of 1568 words of 16
bits, on-chip program ROM of 256-words, direct
addressing of up to 64K-words of external
program and 64K-words of data memory space,
and multiprocessor interface features for sharing
global memory minimize unnecessary data
transfers to take full advantage of the capabilities
of the processor.
The SMJ320C26 scaling shifter has a 16-bit input
connected to the data bus and a 32-bit output
connected to the ALU. The scaling shifter
produces a left shift of 0 to 16 bits on the input
data, as programmed in the instruction. The LSBs
of the output are filled with zeroes, and the MSBs
may be either filled with zeroes or sign-extended,
depending upon the status programmed into the
SXM (sign-extension mode) bit of status register
ST1.
