Featuring Arduino Nicla Voice with Speech Recognition, BL5.0 and Much More

Posted on by Rakesh Kumar, Ph.D.

Recently, Arduino has introduced a small, low-power integrated module with AI capabilities. Syntiant NDP120 processor designed for Deep Learning applications and ANNA-B112 u-Blox module for wireless communication forms the basis of the Arduino Nicla Voice. The Nicla Voice, much like the recently highlighted Nano 33 BLE Sense Rev2, features an ANNA-B112 module built on the Nordic nRF52 SoC series and a Syntiant Neural Decision Processor.

One Syntiant Core 2 U-LP deep neural network inference engine, one Tensilica HiFi 3 Audio DSP, and one Arm Cortex M0 (up to 48MHz), 48KB of static random access memory (SRAM) are all included in the Syntiant NDP120.

The nRF52832 features an Arm Cortex M4 processor (up to 64 MHz), 64KB of SRAM, and 512KB of Flash-mapped FIFOs. Further, it has a 12-bit/200 ksps ADC, 2.4-2.4835 GHz BL 5.0 (through the ARM Cordio stack), and 4.2 (via ArduinoBLE). Not only that but there’s also a 32MHz oscillator on the inside and a 1.8V power supply.

 

NDP120 block diagram

This datasheet clearly states that  NDP120 supports “concurrent neural networks, 2D convolution, depth-wise convolution, the recurrent neural network including LSTM and GRU, average and max pooling”.

According to Hackster.io, the Arduino Nicla Voice will cost about $82. To sign up for the waiting list, look at the product announcement. On the Hardware page for the Arduino Nicla Voice, you can find the datasheet, libraries, schematics, STEP files, and other guides.

Arduino Nicla Voice pinout

It appears that the Nicla Voice, like the Nano 33 BLE Sense Rev2, uses IMUs manufactured by BOSCH. These IMUs consist of a 6-axis gyroscope (BMI270) and a 3-axis accelerometer (BMM150).

Arduino talks about its ability to recognize speech,

“the Nicla Voice speeds up the tempo of product development, whether your launch requires solutions that use voice to play music, make phone calls or pull up the blinds. It makes devices smarter by allowing for multiple wake words, replacing buttons users struggle with, and helping designers integrate unobtrusive voice-command systems into stylish accessories”.

The Arduino Nicla Voice has a list of specs, such as 16 MB SPI Flash storage, BLE 5.0, and Bluetooth mesh connectivity. I/O Interfaces are done through GPIOs 1.8V/3.3V, 10x Digital I/Os, 12x PWM pins, 1x I2C bus (with ESLOV connector), 1x UART, 1x SPI, and 2x ADC. The 6-Axis IMU (BMI270) and 3-Axis IMU (BMM150), 1x Digital MEMS Microphone (IM69D130), and 1x RGB LED are some of the other features. The USB is a Micro-B port. The temperature range is 0°C to 70°C. It gets its power from a 3.3V USB-B Micro port, a 3.7V Li-Po battery, and a JST connector. The size and weight are both 22.86 x 22.86 mm and 2g.

High Geared RISC-V ESP32-P4 SoC Loaded with GPIOs by Espressif

Posted on by Rakesh Kumar, Ph.D.

The ESP32 family of system-on-chips (SoCs) from Espressif now includes a new member. The RISC V-based ESP32-P4 has three processing cores, fifty general-purpose input/output (GPIO) pins, and a full complement of security options. Interestingly, though, the chip lacks the RF radio.

Despite having three CPU cores, Espressif set them up as a “big-little” architecture with a high-performance (dual-core) and low-power (single-core) setup, respectively. When they aren’t needed, high-performance cores should be turned off.

The ESP32-P4‘s high-performance central processing unit (CPU) is a 400 MHz dual-core RISC-V CPU. The SRAM on the chip is 768 kilobytes in size. When paired with an external PSRAM, however, the on-chip RAM acts as a cache for the immediate area. For low latency buffer access, there are also eight kilobytes of zero-wait tightly linked memory (TCM).

One RISC-V core with up to 40 MHz of clock speed plus specialized SRAM, ROM, and peripherals make up the low-power system. It’s also where the system-on-power chip’s management circuitry is located (PMU). It has a touch interface, a temperature sensor, and low-speed serial interfaces as its peripherals.

The ESP32-P4’s superior security is one of Espressif’s main selling points. Secure boot, flash encryption, a genuinely random number generator, digital signature management, access rights, and privileged isolation are all part of the package.

The 50 general-purpose I/O pins are the most ever included in an Espressif system-on-chip. MIPI (Camera and Display) ports, hardware accelerators for h264 and JPEG, USB, Ethernet, and many more are among the various peripherals available for high-performance CPUs. User interface options on the ESP32-P4 include capacitive touch, speech recognition, and CSI and DSI interfaces. One can use a Pixel Processing Accelerator, which is a piece of hardware, to speed up the processing of graphical displays.

The ESP32-P4 is the first member of the ESP32 series without a radio frequency (RF) transceiver of any type. Wi-Fi, Bluetooth, and other 2.4 GHz wireless technologies are not included. Instead, the ESP32-P4 can communicate with other devices in the ESP32 family using ESP-Hosted, ESP-AT, or a third-party solution, as claimed by Espressif. Wire-based Ethernet is also an option. Overall, the ESP32-P4 is made for edge computing applications that require powerful processing, a sophisticated human-machine interface, and robust security.

The Espressif-IDF will, of course, support the brand-new ESP32-P4 SoC. They promised additional ESP32-P4 details during the next three weeks, and they delivered. Please see the Espressif statement for further information.

Implementing the 100 MHz 6502 In an FPGA

Posted on by Tope Oluyemi

Jürgen Mülle has posted details of re-implementing the 65C02 in an FPGA, in a pin-compatible format that enables you to upgrade old computers and games to a 100 MHz clock rate! Speaking about the project, Jürgen says:

“The idea of implementing a CPU core inside an FPGA is not new, of course. In fact, the CPU core I am using is not my own, but was developed as a 6502 core by Arlet Ottens, and extended to cover the 65C02 opcodes by Ed Spittles and David Banks.”

He started by designing a circuit board that is the same size as a 40-pin dual inline package and has pins that correspond to the 65C02 pinout. This board was then fitted with a Spartan-6 FPGA and 64 kByte of on-chip RAM. He implemented logic within the FPGA that is able to interact with the external 65C02 bus in accordance with the clock signal from the host system. The CPU core within the FPGA clocks at a speed of 100 MHz. The goal is to create a single accelerator that can be used with 6502 and 65C02-based host computers, simply by plugging it into the CPU socket.

The FPGA board must be aware of the memory map of its host in order to determine where the host has memory-mapped I/O. It can store up to 16 different memory maps and switch between them using a mini DIP switch. When the 65F02 is turned on, it takes all of the RAM and ROM content from the host and stores it in its own internal RAM, excluding the I/O area. Once the CPU is running, the internal memory is accessed at 100 MHz for all bus operations, except for I/O addresses. In this case, the CPU will pause and an external bus cycle will be initiated at the external clock rate.

Supported host systems


One of the host systems the project supports are the Chess computers. Jürgen Mülle primarily concentrated on Mephisto chess computers, because they are the main focus of Roland’s collector’s desires. However, he hopes to extend the project to many other items on the wishlist. including Fidelity (Elite A/S Budapest and Glasgow, Prestige, Avantgarde), Novag (Super Constellation, Super Expert C), SciSys (Turbostar),

For microcomputers, the project supports the two 6502-based members of the classic 1977 “Trinity” of home computers – the Apple II and the Commodore PET series. Also, in the future, it will be possible and worthwhile to offer support for some slightly later machines like; The Acorn BBC Micro, Atari 400 and 800, and possibly the Commodore C64 come.


Note that this is a hobby project, and Jürgen Mülle has no plans at the moment to take it commercial. Some of the small-form-factor PCBs have been assembled, and have been successfully tested in the above-mentioned computers. For more information, visit the project page.
