## Detailed Description

## Macro Definition Documentation

## ◆ QURT_HTHREAD_L1I_PREFETCH

#define QURT_HTHREAD_L1I_PREFETCH 0x1

Enables hardware L1 instruction cache prefetching.

Definition at line 28 of file mini_qurt.h.

## ◆ QURT_HTHREAD_L1D_PREFETCH

#define QURT_HTHREAD_L1D_PREFETCH 0x2

Enables hardware L1 data cache prefetching.

Definition at line 29 of file mini_qurt.h.

## ◆ QURT_HTHREAD_L2I_PREFETCH

#define QURT_HTHREAD_L2I_PREFETCH 0x4

Enables hardware L2 instruction cache prefetching.

Definition at line 30 of file mini_qurt.h.

## ◆ QURT_HTHREAD_L2D_PREFETCH

#define QURT_HTHREAD_L2D_PREFETCH 0x8

Enables hardware L2 data cache prefetching.

Definition at line 31 of file mini_qurt.h.

## ◆ QURT_HTHREAD_DCFETCH

#define QURT_HTHREAD_DCFETCH 0x10

Enables DC fetch to the provided virtual address.

\ DC fetch instructs the hardware that a data memory access is likely. \ Instructions are dropped in the case of high bus utilization.

Definition at line 34 of file mini_qurt.h.

Definition at line 36 of file mini_qurt.h.

## ◆ QURT_THREAD_ATTR_TCB_PARTITION_RAM

#define QURT_THREAD_ATTR_TCB_PARTITION_RAM 0

Creates threads in RAM/DDR.

Definition at line 37 of file mini_qurt.h.

## ◆ QURT_THREAD_ATTR_TCB_PARTITION_TCM

#define QURT_THREAD_ATTR_TCB_PARTITION_TCM 1

Creates threads in TCM.

Definition at line 38 of file mini_qurt.h.

## ◆ QURT_THREAD_ATTR_TCB_PARTITION_DEFAULT

#define QURT_THREAD_ATTR_TCB_PARTITION_DEFAULT QURT_THREAD_ATTR_TCB_PARTITION_RAM

Backward compatibility.

Definition at line 39 of file mini_qurt.h.

## ◆ QURT_THREAD_ATTR_PRIORITY_DEFAULT

#define QURT_THREAD_ATTR_PRIORITY_DEFAULT 255

Definition at line 40 of file mini_qurt.h.
