__RV_PKBB32()

__STATIC_FORCEINLINE unsigned long __RV_PKBB32	(	unsigned long	a,
		unsigned long	b
	)

PKBB32 (Pack Two 32-bit Data from Both Bottom Half)

Type: DSP (RV64 Only)

Syntax:

PKBB32 Rd, Rs1, Rs2
PKBT32 Rd, Rs1, Rs2
PKTT32 Rd, Rs1, Rs2
PKTB32 Rd, Rs1, Rs2

Purpose:
Pack 32-bit data from 64-bit chunks in two registers.

• PKBB32: bottom.bottom
• PKBT32: bottom.top
• PKTT32: top.top
• PKTB32: top.bottom

Description:
(PKBB32) moves Rs1.W[0] to Rd.W[1] and moves Rs2.W[0] to Rd.W[0]. (PKBT32) moves Rs1.W[0] to Rd.W[1] and moves Rs2.W[1] to Rd.W[0]. (PKTT32) moves Rs1.W[1] to Rd.W[1] and moves Rs2.W[1] to Rd.W[0]. (PKTB32) moves Rs1.W[1] to Rd.W[1] and moves Rs2.W[0] to Rd.W[0].

Operations:

Rd = CONCAT(Rs1.W[_*0*_], Rs2.W[_*0*_]); // PKBB32
Rd = CONCAT(Rs1.W[_*0*_], Rs2.W[_*1*_]); // PKBT32
Rd = CONCAT(Rs1.W[_*1*_], Rs2.W[_*1*_]); // PKTT32
Rd = CONCAT(Rs1.W[_*1*_], Rs2.W[_*0*_]); // PKTB32

Parameters

[in]	a	unsigned long type of value stored in a
[in]	b	unsigned long type of value stored in b

Returns

value stored in unsigned long type
