(TBD) +-- Author: +-- . D.F. Brouwer +-- Design name: +-- . iwave_synthesis_wpfb_alma +-- Purpose: +-- . Wrapper for wpfb (wideband polyphase filterbank with ports for subband +-- statistics and streaming interfaces) synthesis design for iwave Agilex 7 +-- (c_tech_agi027_xxxx). +-- . Implements the functionality of the subband filterbank (Fsub) using the +-- ALMA design parameters. +-- Description: +-- . The subband filterbank seperates the incoming timestamped ADC samples into +-- ?? (TBD) frequency bands called subbands. +-- . It implements a critically sampled poly-phase filterbank (PFB). The PFB +-- consists of a poly-phase finite impulse response (PFIR) filter per real +-- input and a complex fast fourier transform (FFT) per 2 real inputs. +-- . The number of points of the FFT is ?? (TBD). +-- Description: +-- . The quantized subbands are output (and used for the SST) because it uses more logic. +-- ____ +-- | | +-- | |--raw----> X (not included in synthesis) +-- |WPFB| +-- | |--quant--> wpfb_unit_out_quant_sosi_arr (more logic = critical timepath is longer) +-- |____| + +library IEEE, common_lib, dp_lib, rTwoSDF_lib, common_mult_lib, fft_lib, wpfb_lib, filter_lib, si_lib, st_lib, mm_lib; +use IEEE.std_logic_1164.all; +use common_lib.common_pkg.all; +use common_lib.common_mem_pkg.all; +use dp_lib.dp_stream_pkg.all; +use rTwoSDF_lib.rTwoSDFPkg.all; +use filter_lib.fil_pkg.all; +use fft_lib.fft_pkg.all; +use wpfb_lib.wpfb_pkg.all; + +entity iwave_synthesis_wpfb_alma is + generic ( + g_wpfb : t_wpfb := c_wpfb_lofar2_subbands_l2ts_18b; -- Instance of the wpfb type (t_wpfb) which is the same config as defined in c_sdp_wpfb_subbands #TODO: Change to ALMA Design parameters + g_nof_streams : natural := 12 -- Number of signals per processing node #TODO: Change to ALMA Design parameters + ); + port ( + dp_clk : in std_logic; -- Same clock, reset for dp as for mm, because of compatibility of Agilex 7. + dp_rst : in std_logic; -- ,, ,, + mm_clk : in std_logic; -- ,, ,, + mm_rst : in std_logic; -- ,, ,, + reg_si_copi : in t_mem_copi := c_mem_copi_rst; + reg_si_cipo : out t_mem_cipo; + ram_fil_coefs_copi : in t_mem_copi := c_mem_copi_rst; + ram_fil_coefs_cipo : out t_mem_cipo; + ram_st_sst_copi : in t_mem_copi := c_mem_copi_rst; -- Subband statistics registers + ram_st_sst_cipo : out t_mem_cipo; + in_sosi_arr : in t_dp_sosi_arr(g_nof_streams - 1 downto 0); + out_quant_sosi_arr : out t_dp_sosi_arr(g_wpfb.nof_wb_streams * g_wpfb.wb_factor - 1 downto 0) + ); +end iwave_synthesis_wpfb_alma; + +architecture str of iwave_synthesis_wpfb_alma is + -- FIR coeffs file is copied to build data/ dir by design revision hdllib.cfg + -- from: $HDL_WORK/libraries/dsp/filter/src/hex + constant c_coefs_file_prefix : string := "data/Coeffs16384Kaiser-quant_1wb"; --#TODO: Check and if needed change to ALMA Design parameters + + constant c_nof_pfb : natural := g_wpfb.nof_wb_streams * g_wpfb.wb_factor; -- Default 6 PFB units, is 6 signal output pairs #TODO: Change to ALMA Design parameters + constant c_in_dat_w : natural := g_wpfb.fil_in_dat_w; -- Default number of input bits of the ADC is 14 #TODO: Change to ALMA Design parameters + + constant c_si_pipeline : natural := 1; + + signal si_sosi_arr : t_dp_sosi_arr(g_nof_streams - 1 downto 0) := (others => c_dp_sosi_rst); + + signal wpfb_unit_in_sosi_arr : t_dp_sosi_arr(c_nof_pfb - 1 downto 0) := (others => c_dp_sosi_rst); + signal wpfb_unit_out_quant_sosi_arr : t_dp_sosi_arr(c_nof_pfb - 1 downto 0) := (others => c_dp_sosi_rst); + +begin + --------------------------------------------------------------- + -- SPECTRAL INVERSION + --------------------------------------------------------------- + u_si_arr : entity si_lib.si_arr + generic map ( + g_nof_streams => g_nof_streams, + g_pipeline => c_si_pipeline, + g_dat_w => c_in_dat_w + ) + port map( + in_sosi_arr => in_sosi_arr, + out_sosi_arr => si_sosi_arr, + + reg_si_mosi => reg_si_copi, + reg_si_miso => reg_si_cipo, + + mm_rst => mm_rst, + mm_clk => mm_clk, + dp_clk => dp_clk, + dp_rst => dp_rst + ); + + --------------------------------------------------------------- + -- POLY-PHASE FILTERBANK + --------------------------------------------------------------- + -- Connect the 12 ADC streams to the re and im fields of the PFB input. #TODO: Change to ALMA Design parameters + p_pfb_streams : process(si_sosi_arr) + begin + for I in 0 to c_nof_pfb - 1 loop + wpfb_unit_in_sosi_arr(I) <= si_sosi_arr(2 * I); + wpfb_unit_in_sosi_arr(I).re <= RESIZE_DP_DSP_DATA(si_sosi_arr(2 * I).data); + wpfb_unit_in_sosi_arr(I).im <= RESIZE_DP_DSP_DATA(si_sosi_arr(2 * I + 1).data); + end loop; + end process; + + -- PFB + u_wpfb_unit_dev : entity wpfb_lib.wpfb_unit_dev + generic map ( + g_wpfb => g_wpfb, + g_use_prefilter => true, + g_stats_ena => false, -- Enables the statistics unit.
