人脸识别部分是在芯片内运算, 还是依靠PC端执行?

在芯片内运算的话, 每秒能处理多少张照片?

Just share 2 ideas

1 - set all int32,int64,pointer to IRAM_ATTR

staic IRAM_ATTR int intval=0;
staic IRAM_ATTR void* ptrval=NULL;

2 - use custom allocator for std::vector<int> , etc

ptr=heap_caps_malloc(size, MALLOC_CAP_32BIT);
return ptr!=NULL?ptr:malloc(size);

Hi, When switch the max_cpu_freq between RTC_CPU_FREQ_80M and RTC_CPU_FREQ_240M , The wifi will 100% reset , all TCP connections lost. [0;32mI (9085) pm_esp32: Frequency switching config: CPU_MAX: 80, APB_MAX: 80, APB_MIN: 80, Light sleep: DISABLED[0m cfg.max_cpu_freq changed to 1 , result 0 I (1504...

Thanks.

Now I know that's the IRAM and it's not able to work as the DRAM

I recently get OOM issue, heap_caps_get_free_size(MALLOC_CAP_DEFAULT) returns 112 heap_caps_get_free_size(MALLOC_CAP_INTERNAL) returns 70284 I want to use the MALLOC_CAP_INTERNAL , but , heap_caps_malloc(size, MALLOC_CAP_DEFAULT) return 0 malloc(size) return 0 heap_caps_malloc(size, MALLOC_CAP_8BIT)...
