@ -15,8 +15,10 @@ Highlights:
|
|||
- Mirny 4-channel wide-band PLL/VCO-based microwave frequency synthesiser
|
||||
- Fastino 32-channel, 3MS/s per channel, 16-bit DAC EEM
|
||||
- Kasli 2.0
|
||||
* Matrix math support on the core device.
|
||||
* Trigonometric functions and miscellaneous math library support on the core device.
|
||||
* ARTIQ Python (core device kernels):
|
||||
- Matrix math support on the core device.
|
||||
- Trigonometric functions and miscellaneous math library support on the core device.
|
||||
- Failed assertions now raise ``AssertionError``\ s instead of aborting kernel execution.
|
||||
* Performance improvements:
|
||||
- SERDES TTL inputs can now detect edges on pulses that are shorter
|
||||
than the RTIO period (https://github.com/m-labs/artiq/issues/1432)
