Release Announcement: Model-Based Design Toolbox for SPT version 1.3.0

[#1]

	Product Release Announcement Automotive Microcontrollers and Processors Model-Based Design Toolbox for SPT - 1.3.0
Austin, Texas, USA November 11th, 2019	Model-Based Design Toolbox for SPT allows fast prototyping of algorithms that handle sampled RADAR signals directly from MATLAB environment via SPT bit-exact Simulator. DownloadLocation: https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=MBDSPT Activation link https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=MBDSPT Release Content (updates relative to previous version) Support for the flowing instructions: ADD FIR HIST IRDX2 IRDX4 MAXS PDMA RDX2 RDX4 SCP SORT (SPT 3.0 only) SUB VMT WIN Add support for Adaptive Scaling for RDX2/RDX4/IRDX2/IRDX4 instructions Add LSFR feature for the PDMA instruction Update SPT 2.0, 2.5 and 2.8 bit exact simulator to version 3.0.0 Update SPT 3.0 bit exact simulator to version 2.0.19. To enable SPT 3.0 simulator a special license is needed. Please contact the NXP support to get access to such license Integrate Help and Examples into MATLAB documentation framework. Opening the MATLAB Help will show new section of “Supplemental Software” for Model-Based Design for SPT Toolbox.              To enable SPT 3.0 simulator a special license is needed. Please contact the NXP support to get access to such license. Redesign all SPT Toolbox examples and added a new standalone RADAR application to showcase object detection capabilities with RADAR SPT instruction: range FFT, doppler FFT, beamforming and peak search

Hi,

Our customers used SPT2.0 with NXP_RADAR_TOOLBOX1.2.0 to run SPT_Example.m normally, but after upgrading to NXP_RADAR_TOOLBOX1.3.0, some errors occurred. Please help to check the reason.

The picture is as follows：

SPT2.0+NXP_RADAR_TOOLBOX1.2.0  is OK

SPT2.0+NXP_RADAR_TOOLBOX1.3.0 have some issues.

Hi,Hao Ren:

I have the same problem with you,having taken a lot time but  failed to solve the problem,could you please tell me how to solve the problem? appreciate very much!

Hello nxf47389‌,

You should uninstall the toolbox SPT_2.0_64-bit. This is one of the earliest version of NXP_RADAR_Toolbox_for_S32R.

The error is because there was added a new argument to the following mex files: rdx2_mex, rdx4_mex, irdx2_mex, and irdx4_mex.

syntax for SPT 2.x
[M_Out, adptv_acc_shift] = rdx2_mex(M_Tw, M_Op, fft_rnd, real_fft, quad_ext, repeat, shft_val, adptv)

[M_Out, adptv_acc_shift] = rdx4_mex(M_Wc_Tw, M_Op, win_type, win_coeff_type, fft_rnd, quad_ext, repeat, shft_val, adptv)

[M_Out, adptv_acc_shift] = irdx2_mex(M_Tw, M_Op, fft_rnd, quad_ext, repeat, shft_val, adptv)

[M_Out, adptv_acc_shift] = irdx4_mex(M_Wc_Tw, M_Op, win_type, win_coeff_type, fft_rnd, quad_ext, repeat, shft_val, adptv)

syntax for SPT 3.0
[M_Out, adptv_acc_shift] = rdx2_mex(M_Tw, M_Op, fft_rnd, real_fft, quad_ext, shft_val, adptv)

[M_Out, adptv_acc_shift] = rdx4_mex(M_Wc_Tw, M_Op, win_type, win_coeff_type, fft_rnd, quad_ext, shft_val, adptv)

[M_Out, adptv_acc_shift] = irdx2_mex(M_Tw, M_Op, fft_rnd, quad_ext, shft_val, adptv)

[M_Out, adptv_acc_shift] = irdx4_mex(M_Wc_Tw, M_Op, win_type, win_coeff_type, fft_rnd, quad_ext, shft_val, adptv)

adptv_acc_shift is the adaptive scaling accumulated shift

adptv is the adaptive scaling type; valid values are:

• 'NO_ADPTV' - disable adaptive scaling
• 'ADPTV_TYPE1' - MSB occupation counter counts unoccupied bits from bit 15 downwards
• 'ADPTV_TYPE2' - MSB occupation counter counts unoccupied bits from bit:
  • 23 downwards for SPT 2.0, 2.8 and 3.0
  • 19 downwards for SPT 2.5
