Architectural Overview
The fast-access register file concept contains 32 x 8-bit
general purpose working registers with a single clock cycle
access time. This means that during one single clock cycle,
one Arithmetic Logic Unit (ALU) operation is executed. Two
operands are output from the register file, the operation is
executed, and the result is stored back in the register file -
in one clock cycle.
Six of the 32 registers can be used as three 16-bits indirect
address register pointers for Data Space addressing -
enabling efficient address calculations. One of the three
address pointers is also used as the address pointer for the
constant table look up function. These added function reg-
isters are the 16-bits X-register, Y-register and Z-register.
