Multiply-Accumulator
MACC Overview
PS006614-1208
The most significant process in digital signal processing is the Multiply-Accumulate
(MACC) function, which forms a sum of products, as the following equation shows.
where x and y are vectors (tables of values, one-dimensional arrays) in memory.
The MACC block on the eZ80190 device performs DSP functions without incurring the
control overhead costs associated with a separate DSP.
The key features of MACC block include:
•
•
•
•
•

Each multiply-accumulate operation completes in a single clock cycle
Two 256 x 16 dual-port RAM spaces labeled x and y
–
–
A set of control registers in the CPU’s I/O space are used to set up the next multiply-
accumulate operation, initiate the operation, determine when the Multiply-
Accumulator completes the current calculation, and retrieve the result
∑

i
The 32-bit output is added to the value stored in 1 of the 2 available 40-bit accu-
mulators
The 40-bit sum is written back to the selected 40-bit accumulator
One port of each RAM is 16-bit Read Only and feeds the multiplier
The second port is 8-bit Read/Write and is connected to the CPU data bus, allow-
ing the dual RAM to be part of the CPU memory space
