Cyclone IV devices leverage the same core fabric as the very successful Cyclone series
devices. The fabric consists of LEs, made of 4-input look up tables (LUTs), memory
blocks, and multipliers.
Each Cyclone IV device M9K memory block provides 9 Kbits of embedded SRAM
memory. You can configure the M9K blocks as single port, simple dual port, or true
dual port RAM, as well as FIFO buffers or ROM. They can also be configured to
implement any of the data widths in
Table 1–7. M9K Block Data Widths for Cyclone IV Device Family
The multiplier architecture in Cyclone IV devices is the same as in the existing
Cyclone series devices. The embedded multiplier blocks can implement an 18 × 18 or
two 9 × 9 multipliers in a single block. Altera offers a complete suite of DSP IP
including finite impulse response (FIR), fast Fourier transform (FFT), and numerically
controlled oscillator (NCO) functions for use with the multiplier blocks. The
