intro

1:10 summary yesterday

4:00 Edge TPU Compiler

7:58 reverse engineering custom instructions set inside edge tpu, invite for google e

8:35 college, Edge TPU custom instructions set

18:08 compare the two things

22:40 first year of tiny corp, think that is the output

26:45 inputs, outputs, customOptions, edgetpu-custom-op

30:05 phrased the whole structure last night, no logging, on our own

32:45 apple iOS version 3 audio dsp

35:55 one instruction documented, how architectures usually work, isa

38:30 crappy code, simple little programs without data

44:30 no debug mode, 0 read, 40 write

48:05 blinking light, sending 8 bytes, got response

51:45 cleanup, omc0, rambist_ctrl_1, program that divide's by 2

1:03:30 only running parse, program doing nothing, identity

1:12:30 Lambda, ReLU, keras layer, how anybody use tensorflow

1:15:50 confirming identity, tf.lite.TFLiteConverter

1:20:22 great tensorflow options, divide's by 2

1:24:55 bad non sub chat, trying to be a meme

1:26:59 what registers

1:30:55 writing simple thing, TF weird scaling

1:38:35 reading cool registers, PC program counter

1:43:29 genomics studies on programs, Efuse00

1:47:55 breakpoints, executeControl, instruction_queue_size, scu_ctrl

2:12:00 kHalted, kIdle, Alex, single step mode goes to Halted mode

2:17:48 scalarCore_BreakPoint, breakpoints work

2:33:55 ordering food, memory dump idea

2:37:20 happier doing this, great team at comma, the verge
