The Register Files
There are two on-chip register files (ALU and Shifter), each
containing two 16 bit registers and each supporting 8
instructions (see Table 4). The instructions for the ALU
register file and the Barrel Shifter Register file are the same.
The Inputs to the register files come from either the ALU or
the Barrel Shifter, and are loaded into the Register files on the
rising edge of CLK.
The register file instructions are latched such that the
instruction will not start executing until the rising edge of the
CLK latches the instruction into the device.
The register file instructions (see Table 4) allow input data
to be loaded into either, neither or both of the registers. Data
is loaded at the end of the cycle in which the instruction is
executing.
The register file instructions allow the output to be sourced
from either of the two registers, the selected output will be valid
during the cycle in which the instruction is executing.
