Enhanced Multiply-Accumulate Unit (EMAC)
The and operator enables the MASK use and causes bit 5 of the extension word to be set. The exact
algorithm for the use of MASK is:
if extension word, bit [5] = 1, the MASK bit, then
Here, oa is the calculated operand address and se_d16 is a sign-extended 16-bit displacement. For
auto-addressing modes of post-increment and pre-decrement, the updated An value calculation is also
shown.
Use of the post-increment addressing mode, {(An)+} with the MASK is suggested for circular queue
implementations.
3.2.3
The accumulator registers store 32-bits of the MAC operation result. The accumulator extension registers
form the entire 48-bit result.
