Filter math accelerator (FMAC)

The FMAC performs arithmetic operations on vectors. It comprises a MAC

(multiplier/accumulator) unit, together with address generation logic that allows it to index

vector elements held in local memory.

The unit includes support for circular buffers on input and output, that allows digital filters to

be implemented. Both finite and infinite impulse response filters can be done.

The unit allows frequent or lengthy filtering operations to be offloaded from the CPU, freeing

up the processor for other tasks. In many cases it can accelerate such calculations

compared to a software implementation, resulting in a speed-up of time critical tasks.

The FMAC main features are:

•

16 x 16-bit multiplier

•

24 + 2-bit accumulator with addition and subtraction

•

16-bit input and output data

•

256 x 16-bit local memory

•

Up to three areas can be defined in memory for data buffers (two input, one output),

defined by programmable base address pointers and associated size registers

•

Input and output buffers can be circular

•

Filter functions: FIR, IIR (direct form 1)

•

Vector functions: dot product, convolution, correlation

•

AHB slave interface

•

DMA read and write data channels

3.26

Flexible static memory controller (FSMC)

The FSMC includes two memory controllers:

•

NOR/PSRAM memory controller

•

NAND/memory controller

The FSMC is also named flexible memory controller (FMC).
